AB  - The quest for sustainable biomaterials with excellent biocompatibility and tailorable properties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high production costs and the lack of bioactivity limit their market penetration. To address this, poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) was combined with a bacterial pigment with strong anticancer activity, prodigiosin (PG), to obtain functionally enhanced PHBV-based biomaterials. The samples were produced in the form of films 115.6–118.8 µm in thickness using the solvent casting method. The effects of PG incorporation on the physical properties (morphology, biopolymer crystallinity and thermal stability) and functionality of the obtained biomaterials were investigated. PG has acted as a nucleating agent, in turn affecting the degree of crystallinity, thermal stability and morphology of the films. All samples with PG had a more organized internal structure and higher melting and degradation temperatures. The calculated degree of crystallinity of the PHBV copolymer was 53%, while the PG1, PG3 and PG3 films had values of 64.0%, 63.9% and 69.2%, respectively. Cytotoxicity studies have shown the excellent anticancer activity of films against HCT116 (colon cancer) cells, thus advancing PHBV biomedical application potential.

AB  - Polyhydroxyoctanoate, as a biocompatible and biodegradable biopolymer, represents an ideal candidate for biomedical applications. However, physical properties make it unsuitable for electrospinning, currently the most widely used technique for fabrication of fibrous scaffolds. To overcome this, it was blended with polylactic acid and polymer blend fibrous biomaterials were produced by electrospinning. The obtained PLA/PHO fibers were cylindrical, smaller in size, more hydrophilic and had a higher degree of biopolymer crystallinity and more favorable mechanical properties in comparison to the pure PLA sample. Cytotoxicity evaluation with human lung fibroblasts (MRC5 cells) combined with confocal microscopy were used to visualize mouse embryonic fibroblasts (MEF 3T3 cell line) migration and distribution showed that PLA/PHO samples support exceptional cell adhesion and viability, indicating excellent biocompatibility. The obtained results suggest that PLA/PHO fibrous biomaterials can be potentially used as biocompatible, biomimetic scaffolds for tissue engineering applications.

AB  - The rapid increase in global plastics production is
also causing an accelerated environmental
pollution. Recently, biotechnological solutions and
enzymatic recycling of poly(ethylene terephthalate)
(PET) waste stream have been put forward and
commercialized1. Increasing recycling and
upcycling rates is the most effective model
approach to plastic circularity. However, mixed
plastic waste is still quite a challenge for both
recycling and upcycling technologies. This study is
focused on the eco-conversion of plastic waste
containing poly(ethylene terephthalate), PET, into
biopolymer, bacterial nanocellulose. Polymer mix
contained selection of commercial biodegradable
plastics (poly(lactic acid), PLA, poly(ε-caprolactone),
PCL, poly(hyoxyl butyrate), PHB) and PET. This
mixture was hydrolysed under aqueous conditions
and hydrolysate was used as carbon source for
Komagataeibacter medellinensis ID13488 and
bacterial nanocellulose (BNC) production. HPLC
analysis confirmed the presence of monomers and
dimers of polymer mix components indicating
existence of potential substrates for BNC
production. BNC production by K. medellinensis
was investigated and optimized in ter of the
amount of carbon source and growth conditions.
Under the most efficient rate in ter of yield, BNC
production was scaled up and the obtained
biopolymer was characterized. The structure of
produced BNC was confirmed by FTIR analysis,
thermal properties by DSC/TG analysis, and the
morphology of material by optical microscopy and
SEM analysis. This research demonstrates how to
put the mixed plastic waste stream into a circular
loop through the biotechnological conversion into
valuable biopolymer.

AB  - New film materials based on bacterial biomolecules polyhydroxyalkanoate (poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) PHBV) and prodigiosin (PG) were produced by
solvent casting as a potential food packaging material. Film precursors were obtained in a
sustainable manner via microbial fermentation using waste stream-based substrates (cooking oil
and second-grade canned meat, after the expiry date). The incorporation of PG into the PHBV has
influenced the morphology and functionality of the obtained materials. PG acted as a nucleating
agent, affecting in turn PHBV/PG film surface morphology. The films were intensively colored,
transparent and blocked UV-light. An increase in PG content decreased film transparency but it
did not affect UV-blocking ability. Migration experiments have shown that films possess the
potential to release PG into lipophilic food simulant media where it has exhibited antioxidative
action. The obtained results suggest that PHBV/PG films can be potentially used as sustainable
and active food packaging materials.

abstract = "New film materials based on bacterial biomolecules polyhydroxyalkanoate (poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) PHBV) and prodigiosin (PG) were produced by
solvent casting as a potential food packaging material. Film precursors were obtained in a
sustainable manner via microbial fermentation using waste stream-based substrates (cooking oil
and second-grade canned meat, after the expiry date). The incorporation of PG into the PHBV has
influenced the morphology and functionality of the obtained materials. PG acted as a nucleating
agent, affecting in turn PHBV/PG film surface morphology. The films were intensively colored,
transparent and blocked UV-light. An increase in PG content decreased film transparency but it
did not affect UV-blocking ability. Migration experiments have shown that films possess the
potential to release PG into lipophilic food simulant media where it has exhibited antioxidative
action. The obtained results suggest that PHBV/PG films can be potentially used as sustainable
and active food packaging materials.",

AB  - Immobilizing antifungal polyenes such as nystatin (Nys) and amphotericin B (AmB) into biodegradable formulations is advantageous compared to free drug administration providing sustained release, reduced dosing due to localized targeting and overall reduced systemic drug toxicity. In this study, we encapsulated Nys and AmB in medium chain length polyhydroxyalkanoates (mcl-PHA) microspheres (7-8 mu m in diameter). The obtained formulations have been validated for antifungal activity in vitro against a panel of pathogenic fungi including species of Candida, Aspergillus, Microsporum and Trichophyton genera and toxicity and efficacy in vivo using the zebrafish model of disseminated candidiasis. While free polyenes, especially AmB, were highly toxic to zebrafish embryos at the effective (MIC) doses, after their loading into mcl-PHA microspheres, inner organ toxicity and teratogenicity associated with both drugs were not observed, even at 100 x MIC doses. The obtained mcl-PHA/polyene formulations have successfully eradicated C. albicans infection and showed an improved therapeutic profile in zebrafish by enhancing infected embryos survival. This approach is contributing to the antifungal arsenal as polyenes, although the first broad-spectrum antifungals on the market are still the gold standard for treatment of fungal infections.

AB  - Novel biodegradable and biocompatible formulations of "old" but "gold" drugs such as nystatin (Nys) and amphotericin B (AmB) were made using a biopolymer as a matrix. Medium chain length polyhydroxyalkanoates (mcl-PHA) were used to formulate both polyenes (Nys and AmB) in the form of films (similar to 50 mu m). Thermal properties and stability of the materials were not significantly altered by the incorporation of polyenes in mcl-PHA, but polyene containing materials were more hydrophobic. These formulations were tested in vitro against a panel of pathogenic fungi and for antibiofilm properties. The films containing 0.1 to 2 weight % polyenes showed good activity and sustained polyene release for up to 4 days. A PHA monomer, namely 3-hydroxydecanoic acid (C10-OH), was added to the films to achieve an enhanced synergistic effect with polyenes against fungal growth. Mcl-PHA based polyene formulations showed excellent growth inhibitory activity against both Candida yeasts (C. albicans ATCC 1023, C. albicans SC5314 (ATCC MYA-2876), C. parapsilosis ATCC 22019) and filamentous fungi (Aspergillus fumigatus ATCC 13073; Trichophyton mentagrophytes ATCC 9533, Microsporum gypseum ATCC 24102). All antifungal PHA film preparations prevented the formation of a C. albicans biofilm, while they were not efficient in eradication of mature biofilms, rendering them suitable for the transdermal application or as coatings of implants.

AB  - New polyhydroxyoctanoate based composites with incorporated TiO2 microfibers were produced. The presence of the inorganic constituent influenced morphology, physical properties and functionality of the obtained biomaterials. The degree of PHO crystallinity decreased in the composites in a TiO2 concentration dependent manner. The composites were stiffer than the neat PHO, however they preserved their flexibility. Biocompatibility and cellular migration studies showed that composites support cell viability and migration. The obtained results suggest that PHO/TiO2 composites could be used as novel biomaterials with tunable properties for biomedical applications.

AB  - Medium-chain polyhydroxyalkanoates (mcl-PHA) are flexible, elastomeric polymers produced by wide range of
bacteria as intercellular storage of carbon and energy. They represent attractive components in biomaterial design
because they are biocompatible, biodegradable and can be obtained using variety of carbon sources including
waste streams[1]. However, being semi-crystalline, all mcl-PHAs are characterized by low melting temperature and
poor tensile strength which can interfere with processing methods and wider biomedical application. Simple way
to improve mcl-PHAs properties is to incorporate a nanophase within biopolymer to obtain nanocomposites.
Nano-sized constituents interact with biopolymer more intimately affecting in turn the obtained nanocomposite
properties as well as functionality. Among inorganic nanofillers, TiO2 nanostructures with high aspect ratio (e.g.
nanofibers) have unique properties that support osteogenic phenotype which makes them suitable for bone tissue
engineering [2].

AB  - Agar-based composites with different Zn-carbonate mineral phase content were prepared by in situ mineralization and the solvent casting method. The mineral phase within the composite films was identified as hydrozincite, Zn-5(CO3)(2)(OH)(6). The presence of the mineral phase improved, both mechanical and water vapor permeability properties of the obtained composite films, in a concentration-dependent manner. The release of zinc ions from composite films is in accepted levels (up to 2.5%), and sufficient to provide complete inhibition growth of S. Aureus. The results of this study suggest that agar/Zn-carbonate composites could be potentially used as affordable, eco-friendly and functional materials with tunable properties for food packaging, agriculture or biomedical application. In situ procedure offers possibilities for tailoring the physical-chemical properties of composite films, by varying the Zn-mineral phase load.

AB  - New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate phase had better compatibility with agar matrix than Cu-phosphate phase. Incorporation of both mineral phases improved mechanical and water vapor barrier properties of the obtained mineralized films, in concentration dependent manner. When 5 mM of carbonate precursor was incorporated into agar matrix, mechanical resistance was enchanced for 44% and water vapor barrier property for 40%. The release of Cu (II) was higher in acidic conditions for both mineralized composites and remained in the range of specific release limits for this metal. In addition, both mineralized composite films exhibited distinctive antimicrobial activity against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria.

abstract = "New agar-based composite films with increasing Cu-carbonate and Cu-phosphate mineral phase content were prepared by in situ mineralization and solvent casting method. SEM and optical analysis revealed that Cu-carbonate phase had better compatibility with agar matrix than Cu-phosphate phase. Incorporation of both mineral phases improved mechanical and water vapor barrier properties of the obtained mineralized films, in concentration dependent manner. When 5 mM of carbonate precursor was incorporated into agar matrix, mechanical resistance was enchanced for 44% and water vapor barrier property for 40%. The release of Cu (II) was higher in acidic conditions for both mineralized composites and remained in the range of specific release limits for this metal. In addition, both mineralized composite films exhibited distinctive antimicrobial activity against Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus aureus) bacteria.

AB  - Two bimetallic (Zn/Cu) alginate based nanocomposites, impregnated with carbonate or phosphate mineral phase, were prepared by a facile procedure. Mineralized samples exhibited different morphologies and properties when compared to the non-mineralized sample. Antimicrobial testing against Escherichia coil, Staphylococcus aureus and Candida albicans showed that mineralized samples are more efficient than non-mineralized in elimination of microorganisms. The results of this study suggest that bimetallic mineralized alginates could be potentially used as affordable, easy to produce antimicrobial materials.

AB  - New mineralized, agar-based nanocomposite films (Zn-carbonate and Zn-phosphate/agar) were produced by a combination of in situ precipitation and a casting method. The presence of minerals significantly influenced the morphology, properties and functionality of the obtained nanocomposites. Reinforcement with the Zn-mineral phase improved the mechanical properties of the carbonate-mineralized films, but had a negligible effect on the phosphate-mineralized samples. Both nanocomposites showed improved optical and thermal properties, better Zn(II) release potential in a slightly acidic environment and exhibited antimicrobial activity against S. aureus. These results suggest that Zn-mineralized agar nanocomposite films could be potentially used as affordable, eco-friendly and active food packaging materials.

AB  - New bioactive and antimicrobial biomaterials were produced by alginate-mediated biomineralization with Zn-mineral phase. The synthesis procedure is simple, cost-effective and resulted in. two different Zn-mineralized alginate nanocomposites, Zn-carbonate/Zn-alginate and Zn-phosphate/Zn-alginate. The presence of Zn-mineral phase and its type, have significantly affected nanocomposite morphology, stability, total metallic loading and potential to release Zn(II) in physiological environment. Antimicrobial experiments showed that both types of Zn-mineralized nanocomposites exhibit strong antimicrobial effect against Escherichia coli, Staphylococcus aureus and Candida albicans. These results suggest that alginate biomineralization, where minerals are salts of essential metallic ions like Zn(II), represents a'good strategy for designing multifunctional biomaterials for potential biomedical applications.

AB  - The aim of this work was to assess phenomena occurring during AgNP transport from nanocomposite Ag/alginate hydrogels under conditions relevant for potential biomedical applications as antimicrobial soft tissue implants. First, we have studied AgNP migration from the nanocomposite to the adjacent alginate hydrogel mimicking soft tissue next to the implant. AgNP deposition was carried out by the initial burst release lasting for similar to 24 h yielding large aggregates on hydrogel surfaces and smaller clusters (similar to 400 nm in size) inside. However, the overall released content was low (0.67%) indicating high nanocomposite stability. In the next experimental series, release of AgNPs, 10-30 nm in size, from Ag/alginate microbeads in water was investigated under static conditions as well as under continuous perfusion mimicking vascularized tissues. Mathematical modeling has revealed AgNP release by diffusion under static conditions with the diffusion coefficient within the Ag/alginate hydrogel of 6.9x10(-19) m(2) s(-1). Conversely, continuous perfusion induced increased AgNP release by convection with the interstitial fluid velocity estimated as 4.6 nm s(-1). Overall, the obtained results indicated the influence of hydrodynamic conditions at the implantation site on silver release and potential implant functionality, which should be investigated at the experimentation beginning using appropriate in vitro systems.

AB  - Here we investigate the dissolution behaviour of copper minerals contained within biocompatible alginate hydrogels. Copper has a number of biological effects and has most recently been evaluated as an alternative to expensive and controversial growth factors for applications in tissue engineering. Precise control and sustained release of copper ions are important due to a narrow therapeutic window of this potentially toxic ion, and alginate would appear to be a good material of choice for this purpose. We found that aqueously insoluble copper minerals could be precipitated during gelling within or mixed into alginate hydrogels in the form of microbeads prior to gelling to serve as depots of copper. These minerals were found to be soluble in a variety of biological fluids relevant to in vitro and in vivo investigations, and the alginate carrier served as a barrier to diffusion of these ions and therefore offered control over the rate and duration of release (Cu2+ release rates observed between 10-750 mu Mol g(-1) h(-1) and duration for up to 32 d). Copper mineral and copper mineralized alginate microbeads were characterized using powder x-ray diffraction, FTIR, thermogravimetric analysis and scanning electron microscopy. Dissolution kinetics were studied based on measurements of copper ion concentrations using colourimetric methods. In addition we characterized the complexes formed between released copper ions and biological fluids by electron paramagnetic spectroscopy which offers an insight into the behaviour of these materials in the body.
