title: [Determination of the biological activity of antibiotics by using dry nutrient media].
abstract: The possibility of using available dry nutrient media Nos. 5 to 12 in assays of antibiotic biological activity with the agar diffusions method was studied with respect to benzylpenicillin, gramicidin S, kanamycin sulfate, kanamycin B, oleandomycin, novobiocin, tetracycline and erythromycin. The dry media were used instead of the respective media prepared with meat hydrolyzate. Optimal conditions of the assays on such media were determined.
