Bacteriocin-producing strain of Lactococcus lactis subsp. diacitilactis S50
(Applied and Environmental Microbiology, 1991)
Lactococcus lactis subsp. diacitilactis S50 produces a bacteriocin, designated bacteriocin S50, which has a narrow antibacterial spectrum. It was active only against Lactococcus species, including a nisin producer exhibiting ...
Agrobacterium rhizogenes-mediated transformation and plant regeneration of four Gentiana species
(Springer, Dordrecht, 1997)
Shoots of micropropagated Gentiana acaulis, G. cruciata, G. lutea, and G. purpurea were inoculated with suspensions of Agrobacterium rhizogenes cells, strains ATCC 15834 or A4M70GUS. Adventitious roots appeared at the sites ...
The Disbalance of α- and β-Globins in Anemic Belgrade Rat Red Blood Cells
(Biochemical and Biophysical Research Communications, 1994)
The Belgrade Laboratory (b/b) rat has an autosomal mutation which in homozygous state induces severe anemia. This study was based on solubilization of total rat globin chains and their separation into α- and β-globins using ...
PspF and IHF bind co-operatively in the psp promoter-regulatory region of Escherichia coli
(Wiley-Blackwell, Hoboken, 1997)
PspF bound to the psp enhancer activates E sigma(54) holoenzyme-dependent transcription of the Escherichia coli phage-shock protein (psp) operon and autogenously represses its own sigma(70)-dependent transcription, thereby ...
The Escherichia coli phage-shock-protein (psp) operon
(Blackwell Science Ltd, Oxford, 1997)
The phage-shock-protein (psp) operon helps to ensure survival of Escherichia coli in tate stationary phase at alkaline pH, and protects the cell against dissipation of its proton-motive force against challenge. It is ...
Construction of improved vectors for gene cloning in Micromonospora melanosporea
(Springer-Verlag, 1994)
Two vectors for Micromonospora melanosporea have been constructed with the Streptomyces plasmid pIJ702 along with the sgm gene (sisomicin-gentamicin resistance gene from M. zionensis) as the second antibiotic resistance ...
Comparative study on cell envelope‐associated proteinases in natural isolates of mesophilic lactobacilli
(Journal of Applied Bacteriology, 1995)
Lactobacilli isolated from different natural sources were screened for the presence of cell envelope‐associated proteinases (Prt+ strains). Among them 17 of 75 tested isolates were Prt+. All Prt+ strains were producers of ...
Origin of rat β-globin haplotypes containing three and five genes
(Molecular Biology and Evolution, 1990)
We have reported in rat three adult β-gene haplotypes containing either five or three genes. Detailed sequence analysis reveals that the leftmost gene is the major gene and that at the opposite end downstream lies the minor ...
Autogenous control of PspF, a constitutively active enhancer-binding protein of Escherichia coli
(Amer Soc Microbiology, Washington, 1997)
Escherichia coli sigma(54)-dependent phage shock protein operon (pspA to -E) transcription is under the control of PspF, a constitutively active activator, sigma(70)-dependent transcription of pspF is under autogenous ...
