[Slightly active Actinomyces streptomycini (Streptomyces griseus) mutants having a protein in the biosynthesis of the streptidine portion of the streptomycin molecule]

Autor: O L, Krasil'nikova, L N, Anisova, A S, Khokhlov

Publikováno v: Antibiotiki. 23(3)

Twelve mutants having a block in biosynthesis of the streptidine part of the streptomyciu molecule were selected under the effect of nitrozomethylbiuret. These 12 strains responded by an increase in the level of the antibiotic production to the addit

[Use of a protoplasting method for altering the qualitative and quantitative composition of the anthracycline complex in Streptomyces peucetius var. caesius]

Autor: O L, Krasil'nikova, L N, Anisova, N B, Romanova, Iu E, Bartoshevich

Publikováno v: Antibiotiki i khimioterapiia = Antibiotics and chemoterapy [sic]. 33(7)

Conditions for efficient regeneration in mutant strains of the doxorubicin-producing organism Str. peucetius var. caesius were developed. The effect of the protoplast regeneration on changes in the proportion of the components of the anthracycline co

[Isolation and identification of an antileukemia substance from Coprinus radiatus]

Autor: L N, Anisova, Iu E, Bartoshevich, O A, Efremenkova, O L, Krasil'nikova, M K, Kudinova

Publikováno v: Antibiotiki i meditsinskaia biotekhnologiia = Antibiotics and medical biotechnology. 32(10)

Conditions for cultivation of basidiomycete Coprinus radiatus on agar media and its submersion fermentation were developed. An antibiotic was isolated from the fermentation broth filtrate by extraction with ethyl acetate followed by purification on a

[Interaction of streptidin-dependent Actinomyces streptomycini (Streptomyces griseus) mutants No. 170 and 145 with mutants having blocks at various stages of streptomycin biosynthesis]

Autor: O L, Krasil'nikova, L N, Anisova, A S, Khokhlov

Publikováno v: Antibiotiki. 23(4)

In complementation analysis of low active streptidine dependent strains of Act. streptomycini, 170 and 145 with mutants having different blocks in biosynthesis of streptomycin it was found that these strains were the donors of some thermostable subst
