A highly potent strain of Bacillus licheniformis 103 that synthesized thermostable alpha-amylase with temperature and pH optima of 90-95 degrees C and 6.0-8.5, respectively, was obtained by mutagenesis and selection. The composition of fermentation m

A method for chromatographic separation and quantitative determination of individual components of the antibiotic virginiamycin, produced by microbiological synthesis (Streptomyces virginiae strain 147), is described. The components, M1-2 and S1-5, w

The level and the character of the Streptomyces virginiae virginiamycin-producing strain's resistance to self-produced antibiotic and a number of antibiotics from different groups were determined. S. virginiae was shown to display constitutive and in

A 8.3 kb cryptic plasmid was isolated from the thermotolerant strain of Bacillus licheniformis 28KA and designated pLT83. The replicative (rep) region was localized on the plasmid map. The pLT83 plasmid labelled in vitro with an antibiotic resistance

Production of bacitracin by Bac. licheniformis 1001 and its spontaneous autolysin resistant variants was studied. It was found that the antibiotic activity of some variants was 1.5--2 times higher than that of the initial strain. No differences in th

A system for obtaining regenerating protoplasts of highly active Bacillus licheniformis 1001 strain was developed. Transformation of protoplasts by pUB110 and pminiKC plasmids (constructed from plasmids pUB110 and pC194) leading to the expression of

As a result of fusion of the protoplasts of B. subtilis and B. licheniformis the majority of the prototrophic hybrids, as well as the auxotrophs with the Thi-Hom-phenotype or the Thi-phenotype acquired capacity for over-production of riboflavin lacki

Recombinants between B. subtilis and B. licheniformis were prepared by fusion of the bacterial protoplasts. Genetically marked strains SB25 trp C hisH and 168 ade-met-leu- of B. subtilis and 1001 ura-thr- and 1001 met- of B. licheniformis were used a
