[Standardization of the index of biological activity of the multi-component antibiotic neomycin]

Autor: O B, Ermolova, V M, Grigor'eva, L P, Snezhnova, N E, Klimova

Publikováno v: Antibiotiki. 28(7)

The characteristic features of determination of the biological activity of neomycin and its separate components A, B and C were studied. Different sensitivity of 5 test microbes to neomycins A, B and C was observed. Bac. subtilis ATCC 6633 and Bac. c

[Use of different nutrient medium variants in determining the antimicrobial activity of neomycin]

Autor: O B, Ermolova, V M, Grigor'eva, E M, Bershteĭn, M S, Poliak

Publikováno v: Antibiotiki i meditsinskaia biotekhnologiia = Antibiotics and medical biotechnology. 32(11)

Gel diffusion regularities with respect to neomycin sulfate substances differing in their composition and the antibiotic separate components were studied on nutrient media of diverse composition. Optimal conditions for standardization of neomycin sul

[Method of membrane filtration for determining the sterility and microbial contamination of antibiotics]

Autor: N E, Klimova, V M, Grigor'eva

Publikováno v: Antibiotiki. 22(2)

During membrane filtration antibiotics belonging to different chemical groups are strictly absorbed on the filters. When the filters are put into liquid thioglycol medium, the residual amounts of the antibiotics on the filters did not prevent the gro

[Experience with the international standardization of the biological activity of the 3d Standard for streptomycin]

Autor: V M, Grigor'eva, L N, Astanina, O B, Ermolova, G I, Loseva, V M, Shatrova

Publikováno v: Antibiotiki. 26(8)

The activity of the third International Standard of streptomycin was determined to be equal to 755 IU/mg with the use of accurately weighed amounts of streptomycin and 78037 IU with the use of streptomycin ampoules. The Standardization Center of the

[Chromatographic method on a thin sorbent layer for studying the purity and quality of the antitumor antibiotic, rubomycin]

Autor: L S, Pokras, L P, Snezhnova, M G, Brazhnikova, V M, Grigor'eva

Publikováno v: Antibiotiki. 23(9)

A method for qualitative and quantitative investigation of rubomycin composition was developed. It was based on chromatographic separation of the antibiotic components in a thin layer of silicic acid followed by their elution and spectrophotometric d

[Tetracycline inactivation by magnesium sulfate in testing for microbial contamination by the membrane filtration method]

Autor: N E, Klimova, V M, Grigor'eva

Publikováno v: Antibiotiki. 22(2)

It was shown that the residual amounts of tetracyclines adsorbed on membrane filters may be inactivated by addition of 2M magnesium sulphate solution to the agar for placing the filters after filtration. The antibiotic inactivation increases the poss

[Antibiotic sensitivity of bifidobacteria and lactobacteria used in the preparation of bifidobacterin and lactobacterin]

Autor: V M, Grigor'eva, L N, Astanina, S V, Lesniak, L N, Evtukhova

Publikováno v: Antibiotiki. 28(6)

Sensitivity of industrial strains and market preparations, such as bifidumbacterin and lactobacterin was studied with respect to 19 antibiotics. The MIC was determined with the method of serial dilutions. It was shown that bifidumbacteria and lactoba
