AB  - The rapid emergence and spread of multidrug-
resistant pathogens present a global
healthcare challenge. One common cause of
resistance and/or tolerance to antibiotics is
biofilms, a complex communities of bacteria
embedded in a self-produced matrix. Biofilm
formation and maturation are regulated by
quorum sensing, a cell density-dependent communication
system that relies on the synthesis,
diffusion, and detection of small signaling molecules
- autoinducers (AIs). Quorum quenching
(QQ) enzymes that cut Ais emerged as a promising
strategy for persistent bacterial infections.
However, a significant drawback for the use of
QQ enzymes as therapeutics is their poor stability
and efficacy in vivo. Since one of the major
health issues linked to biofilm development is
persistent wound infections, our goal was to
improve enzyme properties by immobilizing it
on a natural biopolymer to make it suitable for
use as a wound dressing. The best candidate for immobilization was YtnP lactonase from Bacillus
paralicheniformis ZP1, as in concentrations
higher than 25 μg/mL it improved the survival of
Pseudomonas aeruginosa PAO1-infected zebrafish,
rescuing 80% of embryos. When combined
with tobramycin or gentamicin, the survival
rate of zebrafish embryos increased to 100%.
Purified YtnP lactonase at a concentration of 1
mg was immobilized on 10 mg of polymer disks
by crosslinking with glutaraldehyde. Specific
modifications of the polymer were also made to
eliminate the use of glutaraldehyde, which is a
skin irritant. In in vivo experiments on a murine
chronic wound model, immobilized enzyme
inhibited biofilm development, cleared already
formed biofilms, and overall improved wound
healing. These results provide a foundation for
the development of advanced wound dressings
that will prevent infection development in
wounds and enable proper therapy for infected
chronic wounds.

AB  - Pseudomonas aeruginosa is an opportunistic pathogen that can cause severe chronic
infections due to its exceptional ability to form a biofilm. Regulation of biofilm formation
is very sophisticated and involves multiple bacterial systems and regulatory pathways.
We found an enzyme MhqO dioxygenase from Bacillus paralicheniformis ZP1, which
was effective in the inhibition of biofilm formation and disruption of mature biofilm
of P. aeruginosa. Our results suggest that MhqO exerts its effect at the adhesion level,
preventing cells from attaching to the surface. We have also shown that the enzyme
stimulates the rhamnolipids synthesis.
To elucidate the mechanism of enzyme action, we analyzed the transcriptome of the P.
aeruginosa PAO1 strain treated with MhqO. Since cell adhesion occurs at the beginning
of the stationary phase growth, the PAO1 strain was treated with MhqO for four hours,
followed by total RNA isolation and cDNA synthesis. Transcriptome sequencing was
performed by Illumina NovaSeq 6000 and data were analyzed by Novogene Bioinformatics
Technology Co., Ltd. (Beijing, China).
Obtained data showed that 122 genes were up-regulated, 41 genes were down-regulated,
and the expression of 5947 genes was not changed. Five genes whose expression was
altered are directly related to biofilm formation. MhqO increased the expression of the
RsmA post-transcriptional regulator in P. aeruginosa. Transcriptome data revealed that pili
IV biosynthesis genes were up-regulated, which is in accordance with literature data that
RsmA positively regulates these genes. The inhibition of cells’ attachment to the surface
could be explained by these results. In addition, RsmA positively regulates rhamnolipid
production but negatively regulates biofilm matrix synthesis, which was supported by
expression levels in the sequenced transcriptome.
Data obtained from transcriptome analysis suggest that P. aeruginosa treated with MhqO
dioxygenase should be more sensitive to oxidative and osmotic stress, as well as to
beta-lactam antibiotics. Our further investigations should confirm these effects at the
phenotypic level as well.

AB  - The adaptability of halophytes to increased soil salinity is related to complex rhizosphere interactions. In this study, an integrative approach, combining culture-independent and culture-dependent techniques was used to analyze the bacterial communities in the endorizosphere of indigenous succulent halophytes Salicornia europaea, Suaeda maritima, and Camphorosma annua from the natural salt marshes of Slano Kopovo (Serbia). The 16 S rDNA analyses gave, for the first time, an insight into the composition of the endophytic bacterial communities of S. maritima and C. annua. We have found that the composition of endophyte microbiomes in the same habitat is to some extent influenced by plant species. A cultivable portion of the halophyte microbiota was tested at different NaCl concentrations for the set of plant growth promoting (PGP) traits. Through the mining of indigenous halotolerant endophytes, we obtained a collection representing a core endophyte microbiome conferring desirable PGP traits. The majority (65%) of the selected strains belonged to the common halotolerant/halophilic genera Halomonas, Kushneria, and Halobacillus, with representatives exhibiting multiple PGP traits, and retaining beneficial traits in conditions of the increased salinity. The results suggest that the root endosphere of halophytes is a valuable source of PGP bacteria supporting plant growth and fitness in salt-affected soils.

AB  - Candidiasis caused by Candida albicans is one of the most common fungal infections in modern society. The limited arsenal of clinical drugs, their side effects and emerging resistance, largely contribute to the low efficacy of current antifungal therapies. The morphogenetic yeast-to-hyphae transition is the key virulence feature for the establishment of local and systemic C. albicans infections. We show that a delfinidin-rich fruit extract from Aristotelia chilensis ([Molina], Stuntz) (maqui berry) inhibits filamentation of C. albicans, in both laboratory and clinical strains. The extract acts synergistically with nystatin, with filament formation completely prevented by the combination of ¼×MIC of nystatin and 0.125 mg/ml of the extract. The combination treatment results in increased survival of C. albicans-infected zebrafish embryos compared to treatment with nystatin. Neither the extract nor its combination with nystatin was toxic at effective doses. These results warrant further investigation of maqui berry extract as adjuvant antifungal treatment.

AB  - soil salinity has numerous negative effects on plant growth and poses
a significant threat to agricultural productivity worldwide. The diversity of
endophytic bacterial communities found in various indigenous halophytes
such as Salicornia europaea, Suaeda maritima, and Camphorosma annua, may
reveal beneficial bacteria with various plant growthpromoting (PGP) properties.
Members of Halomonas, the largest genus of the family Halomonadaceae,
are rod-shaped, gram-negative, moderately halophilic bacteria that have been
increasingly isolated from various saline environments, including halophyte
tissues. As part of the halophytic microbiota, halotolerant plant growth-promoting
endophytic bacteria can contribute to plant host growth, productivity, and
fitness under abiotic and biotic stresses. The use of halotolerant PGP bacteria
represents a good alternative strategy to mitigate the effects of salt stress in
crops and to recover saline soils. The aim of this study was to isolate halotolerant
bacteria from halophyte roots, and evaluate their PGP ability and their effect on
germination parameters of selected crops. The endophytic bacterial communities
in the roots of halophytes from natural saline soil in Slano Kopovo (Serbia)
were analyzed using culture-dependent techniques. The genus Halomonas was
the predominant among the halotolerant root-associated bacteria of analyzed
halophytes. We have isolated seven Halomonas sp. strains, six of which were
closely related (>99,86% similarity) to Halomonas songnenensis, a moderately
halophilic bacterium from saline and alkaline soils. Obtained isolates were tested
at different sodium chloride concentrations for a range of PGP traits at
different concentrations of sodium chloride. The selected strains were used to
inoculate seeds iand monitor of the germination process of barley, sunflower,
and wheat under conditions of elevated salinity. Most of the isolates tolerate
the NaCl concentration up to 18% and showed multiple PGP features with some
of them retained even in the presence of additional salt concentrations. The
germination test results showed that Halomonas seed inoculation positively
affected barley germination parameters in conditions with and without added
salt. The observed traits can be further exploited to improve plant growth and
augment the salt tolerance of agricultural production on saline soils.

AB  - The present study reports the potential application of star-shaped poly(epsilon-caprolactones) with different number of arms as new drug delivery matrix. Linear and star-shaped PCL ibuprofen loaded microspheres were prepared using oil-in-water (o/w) solvent evaporation technique and characterized with FTIR, DSC, XRD and SEM analysis. High yield, encapsulation efficiency and drug loadings were obtained for all microspheres. FTIR analysis revealed the existence of interactions between polymer matrix and drug, while the DSC analysis suggested that drug was encapsulated in an amorphous form. SEM analysis confirmed that regular, spherical in shape star-shaped microspheres, with diameter between 80 and 90 mu n, were obtained, while quite larger microspheres, 110 mu m, were prepared from linear PCL. The advantage of using starshaped PCL microspheres instead of linear PCL was seen from drug release profiles which demonstrated higher amount of drug released from star-shaped polymer matrix as a consequence of their branched, flexible structure. Microspheres prepared from the polymers with the most branched structure showed the highest amount of the released drug after 24 h. Finally, cytotoxicity tests, performed using normal human fibroblasts (MRCS), indicated the absence of cytotoxicity at lower concentrations of microspheres proving the great potential of star-shaped PCL systems in comparison to linear ones.

FTIR analysis revealed the existence of interactions between polymer matrix and drug, while the DSC analysis suggested that drug was encapsulated in an amorphous form. SEM analysis confirmed that regular, spherical in shape star-shaped microspheres, with diameter between 80 and 90 mu n, were obtained, while quite larger microspheres, 110 mu m, were prepared from linear PCL. The advantage of using starshaped PCL microspheres instead of linear PCL was seen from drug release profiles which demonstrated higher amount of drug released from star-shaped polymer matrix as a consequence of their branched, flexible structure. Microspheres prepared from the polymers with the most branched structure showed the highest amount of the released drug after 24 h. Finally, cytotoxicity tests, performed using normal human fibroblasts (MRCS), indicated the absence of cytotoxicity at lower concentrations of microspheres proving the great potential of star-shaped PCL systems in comparison to linear ones.",

AB  - Bacterial infections have become increasingly difficult to treat due to the occurrence of antibiotic-resistant strains. A promising strategy to increase the efficacy of therapy is to combine antibacterials with agents that decrease pathogen virulence via the modulation of the quorum sensing (QS). Lactonases inhibit acylated homoserine lactone (AHL)-mediated QS in Gram-negative bacteria, including the leading nosocomial pathogen Pseudomonas aeruginosa. Here we describe the characteristics of heterologously expressed YtnP lactonase from Bacillus paralicheniformis ZP1 (YtnP-ZP1) isolated from agricultural soil using the culture enrichment method. Purified YtnP-ZP1 hydrolyzed different AHLs with preference to substrates with long acyl residues as evaluated in assays with biosensors and HPLC. The enzyme showed good thermostability and activity in a wide temperature range. YtnP-ZP1 in 50 mu g mL(-1) concentration reduced the amount of P. aeruginosa-produced long-chain AHLs by 85%, while it hydrolyzed 50% of short-chain AHLs. Incubation of P. aeruginosa PAO1 with YtnP-ZP1 reduced its swarming motility and elastolytic activity without bactericidal effect. YtnP-ZP1 caused the inhibition of biofilm formation and disintegration of mature biofilms in P. aeruginosa PAO1 and multiresistant clinical strain BR5H that was visualized by crystal violet staining. The treatment with YtnP-ZP1 in concentrations higher than 25 mu g mL(-1) improved the survival of P. aeruginosa PAO1-infected zebrafish (Danio rerio), rescuing 80% of embryos, while in combination with tobramycin or gentamicin survival rate increased to 100%. The treatment of P. aeruginosa PAO1 biofilms on infected zebrafish tail wounds with 50 mu g mL(-1) YtnP-ZP1 and 2 x MIC tobramycin led to infection clearing in 2 days. The extensive toxicity studies proved YtnP-ZP1 was non-toxic to human cells and zebrafish. In conclusion, novel YtnP-ZP1 lactonase with its effective anti-virulence activity could be used to increase the efficacy of clinically approved antibiotics in clearing both systemic and biofilm-associated P. aeruginosa infections.

AB  - Three Streptomyces sp. strains with a multitude of target enzymatic activities confirmed by functional screening, namely BV129, BV286 and BV333, were subjected to genome sequencing aiming at the annotation of genes of interest, in-depth bioinformatics characterization and functional expression of the biocatalysts. A whole-genome shotgun sequencing followed by de novo genome assembly and annotation was performed revealing genomes of 6.4, 9.4 and 7.3 Mbp, respectively. Functional annotation of the proteins of interest resulted in between 2047 and 2763 putative targets. Among the various enzymatic activities that the three Streptomyces strains demonstrated to produce by functional screening, we focused our attention on transaminases (TAs) and laccases due to their high biocatalytic potential. Bioinformatics search allowed the identification of a putative TA from Streptomyces sp. BV333 as a potentially novel broad substrate scope TA and a putative laccase from Streptomyces sp. BV286 as potentially novel blue multicopper oxidase. The two sequences were cloned and overexpressed in Escherichia coli and the two novel enzymes, transaminase Sbv333-TA and laccase Sbv286-LAC, were characterized. Interestingly, both enzymes resulted to be exceptionally thermostable, Sbv333-TA showing a melting temperature (T-M = 85 degrees C) only slightly lower compared to the T-M of the most thermostable transaminases described to date (87-88 degrees C) and Sbv286-LAC being even thermoactivated at temperature  gt 60 degrees C. Moreover, Sbv333-TA showed a broad substrate scope and remarkably demonstrated to be active in the transamination of beta-ketoesters, which are rarely accepted by currently known TAs. On the other hand, Sbv286-LAC showed an improved activity in the presence of the cosolvent acetonitrile. Overall, it was shown that a combination of approaches from standard microbiological and biochemical screens to genome sequencing and analysis is required to afford novel and functional biocatalysts.

AB  - Biocatalytic oxidations mediated by laccases are gaining importance due to their versatility and beneficial environmental effects. In this study, the oxidation of 1,4-dihydropyridines has been performed using three different types of bacterial laccase-based catalysts: purified laccase from Bacillus licheniformis ATCC 9945a (BliLacc), Escherichia coli whole cells expressing this laccase, and bacterial nanocellulose (BNC) supported BliLacc catalysts. The catalysts based on bacterial laccase were compared to the commercially available Trametes versicolor laccase (TvLacc). The oxidation product of 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate was obtained within 7-24 h with good yields (70-99%) with all three biocatalysts. The substrate scope was examined with five additional 1,4-dihydropyridines, one of which was oxidized in high yield. Whole-cell biocatalyst was stable when stored for up to 1-month at 4 degrees C. In addition, evidence has been provided that multicopper oxidase CueO from the E. coli expression host contributed to the oxidation efficiency of the whole-cell biocatalyst. The immobilized whole-cell biocatalyst showed satisfactory activity and retained 37% of its original activity after three biotransformation cycles.

AB  - We have studied the effect of compositions and methods of preparation on the physico-chemical and biocompatible behavior of the hydrogel matrices. Hydrogel matrices are synthesized by free radical polymerization of 2-hydroxyethyl methacrylate net and with gelatin. Highly porous hydrogel structures were obtained by porogenation, and by cryogenic treatment followed by freeze-drying. All samples were characterized for structural, morphological, absorption, degradation and in vitro (healthy human fibroblast cell line) and in vivo (zebrafishDanio rerio) biocompatible properties. The obtained results show that cryo samples, especially with gelatin show better, favorable absorption, morphological and biocompatible properties in comparison with PHEMA samples, which makes these materials highly attractive for biomedical uses.

AB  - Laccases are multicopper-oxidases with variety of biotechnological applications. While predominantly used, fungal laccases have limitations such as narrow pH and temperature range and their production via heterologous protein expression is more complex due to posttranslational modifications. In comparison, bacterial enzymes, including laccases, usually possess higher thermal and pH stability, and are more suitable for expression and genetic manipulations in bacterial expression hosts. Therefore, the aim of this study was to identify, recombinantly express, and characterize novel laccases from Pseudomonas spp. A combination of approaches including DNA sequence analysis, N-terminal protein sequencing, and genome sequencing data analysis for laccase amplification, cloning, and overexpression have been used. Four active recombinant laccases were obtained, one each from P. putida KT2440 and P. putida CA-3, and two from P. putida F6. The new laccases exhibited broad temperature and pH range and high thermal stability, as well as the potential to degrade selection of synthetic textile dyes. The best performing laccase was CopA from P. putida F6 which degraded five out of seven tested dyes, including Amido Black 10B, Brom Cresol Purple, Evans Blue, Reactive Black 5, and Remazol Brilliant Blue. This work highlighted species of Pseudomonas genus as still being good sources of biocatalytically relevant enzymes.

AB  - Petrochemical plastics are generally recalcitrant to microbial degradation and accumulate in the environment. Biodegradable polymers obtained synthetically like poly(epsilon-caprolactone) (PCL) or poly-hydroxyalkanoates (PHA), obtained biotechnologically, have shown great potential as a replacement for petroleum-based plastics. Nevertheless, their biodegradation and environmental faith have been less examined. In this study, thin films of PCL (200 mu m) and medium chain length PHA (mcl-PHA, 70 M fraction of 3-hydroxyoctanoate and 30 M fraction of 3-hydroxydecanoate, 600 mu m) were exposed to total protein preparations (extracellular proteins combined with a crude cell extract) of soil isolates Pseudomonas chiororaphis B-561 and Streptomyces sp. BV315 that had been grown on waste cooking oil as a sole carbon source. Biodegradation potential of two polyesters was evaluated in buffer with total protein preparations and in a laboratory compost model system augmented with selected bacteria. Overall, PCL showed better biodegradation properties in comparison to mcl-PHA. Both materials showed surface erosion after 4-weeks of exposure to total protein preparations of both strains, with a moderate weight loss of 1.3% when P. chlororaphis13-561 was utilized. In laboratory compost model system PCL and mcl-PHA showed significant weight loss ranging from 13 to 17% when Streptomyces sp. BV315 culture was used. Similar weight loss of PCL and mcl-PHA was achieved for 4 and 8 weeks, respectively indicating slower degradation of mcl-PHA. Growth on waste cooking oil as a sole carbon source increased the potential of both tested strains to degrade PCL and mcl-PHA, making them good candidates for augmentation of compost cultures in waste management of both waste cooking oils and biodegradable polymers.

AB  - Bacterial nanocellulose (BNC) emerged as an attractive advanced biomaterial that provides desirable properties such as high strength, lightweight, tailorable surface chemistry, hydrophilicity, and biodegradability. BNC was successfully obtained from a wide range of carbon sources including sugars derived from grass biomass using Komagataeibacter medellinensis ID13488 strain with yields up to 6 g L-1 in static fermentation. Produced BNC was utilized in straightforward catalyst preparation as a solid support for two different transition metals, palladium and copper with metal loading of 20 and 3 wt%, respectively. Sustainable catalysts were applied in the synthesis of valuable fine chemicals, such as biphenyl-4-amine and 4'-fluorobiphenyl-4-amine, used in drug discovery, perfumes and dye industries with excellent product yields of up to 99%. Pd/BNC catalyst was reused 4 times and applied in two consecutive reactions, Suzuki-Miyaura cross-coupling reaction followed by hydrogenation of nitro to amino group while Cu/BNC catalyst was examined in Chan-Lam coupling reaction. Overall, the environmentally benign process of obtaining nanocellulose from biomass, followed by its utilisation as a solid support in metal-catalysed reactions and its recovery has been described. These findings reveal that BNC is a good support material, and it can be used as a support for different catalytic systems.

AB  - Biocatalytic potential of Streptomyces strains isolated from the rhizosphere of plants and from mycorrhizosphere of fungi has been investigated. A total of 118 Streptomyces isolates were selected and functionally screened for 10 different biotechnologically important enzymatic activities: hydrolase (cellulase, cutinase, gelatinase, lipase, protease, polyhydroxyalkanoate (PHA) depolymerase), phenol oxidase and peroxidase (laccase, tyrosinase, and lignin peroxidase), and aminotransferase. Out of 118 tested Streptomyces spp., 90% showed at least one enzymatic activity. The most abundant were enzymes involved in the biomass degradation, as the production of cutinase, cellulase, and lignin peroxidase were detected in 31%, 40%, and 48% of the isolates, respectively. The improved specific activities of lipase (isolates BV315 and BV100) and tyrosinase (isolates BV87 and BV88) were shown in comparison with the industrially relevant activities of Pseudomonas strains. Plant rhizosphere soils were more prolific source of Streptomyces strains with biocatalytic potential in comparison with mycorrhizosphere soils. Overall, 284 enzyme activities among 118 Streptomyces isolates have been detected. This is the first comprehensive screening of Streptomyces isolates from rhizosphere and mycorrhizosphere soils for novel biocatalysts, showing that specific environmental habitats, such as rhizosphere soils, are treasure troves of Streptomyces with biocatalytic potential.

AB  - About 20,100 research publications dated 2000-2017 were recovered searching the PubMed and Web of Science databases for Streptomyces, which are the richest known source of bioactive molecules. However, these bacteria with versatile metabolism are powerful suppliers of biocatalytic tools (enzymes) for advanced biotechnological applications such as green chemical transformations and biopharmaceutical and biofuel production. The recent technological advances, especially in DNA sequencing coupled with computational tools for protein functional and structural prediction, and the improved access to microbial diversity enabled the easier access to enzymes and the ability to engineer them to suit a wider range of biotechnological processes. The major driver behind a dramatic increase in the utilization of biocatalysis is sustainable development and the shift toward bioeconomy that will, in accordance to the UN policy agenda "Bioeconomy to 2030," become a global effort in the near future. Streptomyces spp. already play a significant role among industrial microorganisms. The intention of this minireview is to highlight the presence of Streptomyces in the toolbox of biocatalysis and to give an overview of the most important advances in novel biocatalyst discovery and applications. Judging by the steady increase in a number of recent references (228 for the 2000-2017 period), it is clear that biocatalysts from Streptomyces spp. hold promises in terms of valuable properties and applicative industrial potential.

AB  - Hydrolytic, enzymatic degradation and composting under controlled conditions of series of triblock PCL/PEO copolymers, PCEC, with central short PEO block (M (n) 400 g/mol) are presented and compared with homopolymer (PCL). The PCEC copolymers, synthesized via ring-opening polymerization of epsilon-caprolactone, were characterized by H-1 NMR, quantitative C-13 NMR, GPC, DSC and WAXS. The introduction of the PEO central segment ( lt  2 wt%) in PCL chains significantly affected thermal degradation and crystallization behavior, while the hydrophobicity was slightly reduced as confirmed by water absorption and moisture uptake experiments. Hydrolytic degradation studies in phosphate buffer after 8 weeks indicated a small weight loss, while FTIR analysis detected changes in crystallinity indexes and GPC measurements revealed bulk degradation. Enzymatic degradation tested by cell-free extracts containing Pseudomonas aeruginosa PAO1 confirmed high enzyme activity throughout the surface causing morphological changes detected by optical microscopy and AFM analysis. The changes in roughness of polymer films revealed surface erosion mechanism of enzymatic degradation. Copolymer with the highest content of PEO segment and the lowest molecular weight showed better degradation ability compared to PCL and other copolymers. Furthermore, composting of polymer films in a model compost system at 37 A degrees C resulted in significant degradation of the all synthesized block copolymers.

AB  - The aim of the study was to evaluate and adapt the PCR-based protocol that utilizes the developed serotype-specific primers to identify Salmonella enterica species and its serotypes that are most frequently isolated from poultry samples in Vojvodina. Using the slide agglutination test, 64 and 33 out of 107 Salmonella isolates were identified as S. Infantis and S. Enteritidis, respectively, while ten isolates were identified as eight different Salmonella serovars. Using the same isolates, presence of 993-bp (bcfC gene), 636-bp (steB gene) and 293-bp (sdf locus) amplicons in multiplex PCR unambiguously identified 31 isolates as S. Enteritidis. Two isolates identified as Enteritidis in slide agglutination test were not identified as such in PCR-based approach since they both were missing 293bp long PCR product. Thirty-nine isolates produced a 727-bp amplicon in the specific simplex PCR, and thus were identified as S. Infantis. The greatest discrepancy in comparison to the results of conventional serotyping has been observed in the case of S. Infantis, since 25 more isolates were noted as S. Infantis by conventional serotyping. Seven isolates, with unexpected PCR profiles stayed unidentified by molecular typing, although they were serotyped as S. Typhimurium (1) and S. Infantis (6). S. Gallinarum serovar has to be additionally confirmed, since it shares the same PCR profile with S. Livingstone. Clearly, PCR-based identification has to be thoroughly checked, verified and adapted if it is to be applied as the routine identification protocol.

AB  - Michael addition of aldehydes to nitro-olefins is an effective method to obtain useful chiral gamma-nitroaldehydes. gamma-Nitroaldehydes are precursors for chiral gamma-aminobutyric acid analogues, which have numerous pharmacological activities and are used for the treatment of neurological disorders. A whole-cell system based on recombinantly expressed 4-oxalocrotonate tautomerase (4-OT) was developed and shown to be an effective biocatalyst for the Michael addition of branched aldehydes to beta-nitrostyrenes. The aim of this study was to investigate the influence of the substitution of the N-terminal proline with lysine and arginine, both containing a reactive epsilon-amino group, on the Michael addition catalyzed by 4-OT. First, the effects of these mutations were examined by in silico analysis, followed by the generation of three terminal lysine mutants. The generated mutants, 4-OT_K, 4-OT_PK and 4-OT_KK were tested for their ability to utilise beta-nitrostyrene (1), (E)-1-nitro-2-(2-thienyl)ethene (2) and trans-p-chloro-beta-nitrostyrene (3) as Michael acceptors with isobutanal (2-methylpropanal) as the donor. For comparison, the lithium salt of lysine was used in the same organocatalytic reactions. In general, the introduction of lysine had a negative effect on Michael additions based on overall product yields. However, additional lysine residues at the N-terminus of the protein resulted in structural changes that enhanced the activity towards 2 and 3. Therefore, the N-terminal proline is important for 4-OT-catalysed Michael-additions, but it is not essential.

AB  - Iron and sulfur oxidizing chemolithoautotrophic acidophilic bacteria, such as Acidithiobacillus species, hold the dominant role in mine environments characterized by low pH values and high concentrations of reduced sulfur and iron compounds, such as ores, rocks and acid drainage waters from mines. On the other hand, heterotrophic microorganisms, especially their biofilms, from these specific niches are receiving increased attention, but their potential eco-physiological roles have not been fully understood. Biofilms are considered a threat to human health, but biofilms also have beneficial properties as they are deployed in waste recycling and bioremediation systems. We have analyzed interactions of the metal tolerant heterotrophic microorganisms in biofilms with iron oxidizing autotrophic bacteria both from the sulphidic mine environment (copper mine Bor, Serbia). High tolerance to Cu2+, Cd2+ and Cr6+ and the presence of genetic determinants for the respective metal tolerance and biofilm-forming ability was shown for indigenous heterotrophic bacteria that included strains of Staphylococcus and Rhodococcus. Two well characterized bacteria-Pseudomonas aeruginosa PAO1 (known biofilm former) and Cupriavidus metallidurans CH34 (known metal resistant representative) were also included in the study. The interaction and survivability of autotrophic iron oxidizing Acidithiobacillus bacteria and biofilms of heterotrophic bacteria during co-cultivation was revealed. Finally, the effect of heterotrophic biofilms on bioleaching process with indigenous iron oxidizing Acidithiobacillus species was shown not to be inhibitory under in vitro conditions.

AB  - Dinuclear gold(III) complexes {[AuCl3](2)(mu-4,4'-bipy)} (1) and {[AuCl3](2)(mu-bpe)} (2) with bridging aromatic nitrogen-containing heterocyclic ligands, 4,4'-bipyridine (4,4'-bipy) and 1,2-bis(4-pyridyl)ethane (bpe), were synthesized and characterized by NMR (H-1 and C-13), UV-vis and IR spectroscopic techniques. The crystal structure of 1 was determined by single-crystal X-ray diffraction analysis, while the DFT M06-2X method was applied in order to optimize the structures of 1 and 2. A detailed mechanistic study was performed using the same DFT approach in order to shed light on the disparate coordination modes of the presently investigated N-heterocyclic ligands and the monocyclic pyrazine, which contains two nitrogen atoms within one ring, toward the AuCl3 fragment. The investigation of the solution stability of 1 and 2 in DMSO revealed that both complexes were sufficiently stable in this solvent at room temperature. Complexes 1 and 2, along with K[AuCl4] and the N-heterocyclic ligands used for their synthesis, were evaluated by in vitro antimicrobial studies against a panel of Gram-positive and Gram-negative bacteria and the fungus Candida albicans. In most cases, complexes 1 and 2 have higher antibacterial activity than K[AuCl4] (MICs for 1 and 2 were in the range 3.9-62.5 mu g mL(-1)), while both of the N-heterocycles did not affect the bacterial growth at concentrations up to 500 mu g mL(-1). On the other hand, the antifungal activity of these two complexes against C. albicans was moderate and lower than that of K[AuCl4]. In order to determine the therapeutic potential of 1 and 2, their antiproliferative effect on the normal human lung fibroblast cell line MRC5 and embryotoxicity on zebrafish (Danio rerio) have also been evaluated. To the best of our knowledge, complexes 1 and 2 are the first examples of dinuclear gold(III) complexes with aromatic six-membered heterocycles containing two nitrogen atoms as bridging ligands.

AB  - Herein, a novel soil bacterium Streptomyces sp. NP10 able to grow outside usual streptomycetes optimum conditions (e.g., at 4 A degrees C, pH 9 and high NaCl concentration), exhibiting atypical hemolytic, DNAse, and cellulolytic activities, is described. This strain produces and excretes into the growth medium large amounts of free long-chain fatty acids (FAs). A concurrent lipidomics study revealed a large structural diversity of FAs with over 50 different n- and branched-chain, (un)saturated, and cyclopropane FAs (C-7-C-30) produced by this strain. Two of these, i-17:0cy9-10 and a-18:0cy9-10, represent new natural products and the first ever identified branched cyclopropane FAs. Both free and bound lipid profiles of Streptomyces sp. NP10 were dominated by saturated branched chain FAs (i-14:0, a-15:0, and i-16:0). Although these free FAs showed only a moderate antimicrobial activity, our results suggest that they could have an ecophysiological role in interspecies signaling with another soil microorganism Pseudomonas aeruginosa. This work represents the first comprehensive report on the structural diversity and complexity of the free FA pool in Streptomyces. A naturally occurring streptomycete, such as Streptomyces sp. NP10, which secretes significant amounts of free long-chain FAs (non-cytotoxic) into the medium, could be useful in microbial biodiesel production.

AB  - The enzyme 4-oxalocrotonate tautomerase (4-OT) encoded by the xylH gene is a part of the degradation pathway of aromatic compounds in Pseudomonas putida mt-2. 4-OT was described to catalyze Michael-type addition of acetaldehyde to beta-nitrostyrene, and the whole cell system based on recombinantly expressed 4-OT has been developed previously. In this study biocatalytic process based on Escherichia coli whole cells expressing 4-OT was significantly improved using immobilization and ex situ product recovery strategies. Whole cell immobilization in alginate beads was applied in biocatalytic production of 4-nitro-3-phenyl-butanal from beta-nitrostyrene and acetaldehyde. Immobilized biocatalyst showed wider pH activity range and could tolerate twofold higher initial concentrations of substrate in comparison to the free whole cell biocatalyst. Beads retained their initial activity over 10 consecutive biotransformations of the model reaction and remained suitable for the repetitive use with 85 % of the initial activity after two months of storage. Bioprocess was further improved by utilizing Amberlite XAD-2 hydrophobic resin for the product recovery. With this modification, the amount of organic solvent was reduced 40-fold in comparison to previously reported method making this biocatalytic process greener.

AB  - Chemoselective reduction of activated carbon-carbon double bond in conjugated nitroalkenes was achieved using Escherichia coli BL21(DE3) whole cells. Nine different substrates have been used furnishing the reduced products in moderate to good yields. 1-Nitro-4-phenyl-1,3-butadiene and (2-nitro-1-propenyl)benzene were successfully biotransformed with corresponding product yields of 54% and 45% respectively. Using this simple and environmentally friendly system 2-(2-nitropropyl)pyridine and 2-(2-nitropropyl)naphthalene were synthesized and characterized for the first time. High substrate conversion efficiency was coupled with low enantioselectivity, however 29% enantiomeric excess was detected in the case of 2-(2-nitropropyl)pyridine. It was shown that electronic properties of the aromatic ring, which affected polarity of the double bond, were not highly influential factors in the reduction process, but the presence of the nitro functionality was essential for the reaction to proceed. 1-Phenyl-4-nitro-1,3-butadiene could not be biotransformed by whole cells of Pseudomonas putida KT2440 or Bacillus subtilis 168 while it was successfully reduced by E. coli DH5 alpha but with lower efficiency in comparison to E. coli BL21(DE3). Knockout mutant affected in nemA gene coding for N-ethylmaleimide reductase (BL21 Delta nemA) could still catalyze bioreductions suggesting multiple active reductases within E. coli BL21(DE3) biocatalyst. The described biocatalytic reduction of substituted nitroalkenes provides an efficient route for the preparation of the corresponding nitroalkanes and introduces the new application of the strain traditionally utilized for recombinant protein expression.

AB  - Biodegradation of phenol in four natural soils (loamy sand, sandy loam, sandy clay loam and loam) by indigenous microorganisms and in soils augmented by the Bacillus sp. PS11 was studied. During the laboratory soil microcosm experiments, the total removal of 2 g of phenol per kg of soil was achieved in all soil types in between 6 and 21 days. All biodegradation data was found to fit very well to saturation kinetics. The most efficient phenol removal was observed in the loamy woodland soil that contained the least amount of sand (42.5%) and the most silt and clay fraction (57.5%) in comparison to other three soil samples. However, amending sandy loam sample to contain more clay (from 13.5% to 30%) negatively affected the phenol removal rate, while increasing sand content (from 74.4% to 90%) resulted in the two times faster phenol removal in comparison to natural soil type. Bacillus sp. PS11 performed well in both pure culture and in the presence of soil microorganisms. Indigenous bacteria from sandy clay loam soil type possessed the ability of phenol bioremediation and almost whole amount of added phenol (2 g kg soil(-1)) was degraded within 9 days, whereas augmentation by Bacillus sp. PS11 improved the phenol removal by 20%. Carrying out small scale soil model experiments and amending soil granulometric properties by addition of clay or sand minerals is suggested as an effective and economically interesting way of enhancing bacterial soil bioremediation.
