[Oxidative-reductive activity of the mycelium as a criterion for assessing inoculate quality in gentamycin biosynthesis]

Autor: V V, Losev, P V, Kotlenska, D P, Tsoneva, T N, Laznikova

Publikováno v: Antibiotiki. 26(7)

The development of the seed mycelium at various stages and temperatures was studied with the method of methylene blue decolorization characterizing the respiration level of the culture and its oxidation-reduction (dehydrogenase) activity. Relationshi

[Effect of different forms of nitrogen in the biosynthesis of gentamicin by a Micromonospora purpurea var. violacea 1935 culture]

Autor: T N, Laznikova, I V, Gracheva, N V, Orlova

Publikováno v: Antibiotiki. 22(7)

The effect of different inorganic sources of reduced and oxidized nitrogen on biosynthesis of gentamicin was studied. It was shown that both the ammonium and the nitrate nitrogen were consumed by the antibiotic-producing organism. Out of all the salt

[Role of cobalt in the biosynthesis of the components of the gentamicin complex]

Autor: T P, Krasnova, T N, Laznikova, E V, Likina, N V, Orlova

Publikováno v: Antibiotiki. 23(1)

It was shown that addition of cobalt ions or vitamin B12 to the fermentation medium resulted in an increase in the level of gentamicin accumulation, the relative content of the most methylated components C1 and C2 in the gentamicin complex being incr

[Development of a gentamicin producer under different culture conditions studied by a method of differential centrifugation of the mycelium in a saccharose density gradient]

Autor: V V, Losev, T N, Laznikova, S V, Dmitrieva

Publikováno v: Antibiotiki. 26(5)

The method of differential centrifugation in the sucrose density gradient (SDG) enabled one to trace the changes in the development of the seed and fermentation mycelium of the gentamicin-producing organism. Correlation between gentamicin distributio

[Effect of cobalt on the growth of a Micromonospora purpurea var. violacea 1935 culture and on the biosynthesis of gentamincin]

Autor: T P, Krasnova, T N, Laznikova, N V, Orlova

Publikováno v: Antibiotiki. 22(3)

The effect of cobalt on growth of Micromonospora purpurea var. violacea 1935 and biosynthess of gentamicin in complex soy-bean meal or "synthetic" gelatin medium was studied. In optimal concentrations cobalt increased the activity level of the cultur

[Significance of pH for the growth of the sisomicin producer and biosynthesis of the antibiotic]

Autor: T N, Laznikova, O S, Fochkina, N V, Orlova

Publikováno v: Antibiotiki. 26(6)

Dependence of the mycelium growth and sisomycin production on the pH values of the fermentation broth was studied in cultures of various ages for 6 hours with the method of pH control within the preset levels. It was shown that the values of pH withi

[Dependence of the component makeup of the gentamicin complex on Micromonospora purpurea var. violacea 1935 cultivation conditions]

Autor: T N, Laznikova, T P, Krasnova, E V, Lipina, N V, Orlova

Publikováno v: Antibiotiki. 23(6)

Dependence of biosynthesis of gentamicin and vitamin B12 on complex and "synthetic" media under conditions of decreased aeration, increased phosphorus levels and non-optimal content of carbon source was studied. The decreased levels of vitamin B12 pr
