[Directed isolation of gram-negative asporogenous bacteria from natural substrates]

Autor: L P, Ivanitskaia, E M, Singal, L E, Bodunkova, L N, Ostanina, M V, Baturina

Publikováno v: Antibiotiki. 29(10)

A method for selective isolation of gramnegative nonsporulating bacteria from soil substrates was developed. The method consists of plating out the substrates on a glucose-yeast medium with addition of benzylpenicillin and nalidixic acid. The isolati

[Effect of microbial and tumor cell adaptation to rubomycin on their uptake of rubomycin and carminomycin]

Autor: L N, Ostanina, L A, Averbukh, V L, Karpov, Iu V, Dudnik, V A, Liashenko

Publikováno v: Antibiotiki. 23(9)

Anthracycline antibiotics rubomycin (daunomycin) and carminomycin rapidly accumulated in the bacterial and ascitic tumor cells and their intracellular concentrations significantly exceeded the concentrations in the medium. The strains of Staph. aureu

[Interaction with DNA of semisynthetic carminomycin and rubomycin derivatives]

Autor: Iu V, Dudnik, L N, Ostanina

Publikováno v: Antibiotiki. 28(1)

The apparent binding constants and the effect of semisynthetic derivatives of carminomycin and rubomycin (anthracycline antibiotics) on DNA fusion were studied. The following semisynthetic derivatives were used. 13-dihydrocarminomycin, 14-hydroxycarm
