[Electrophoretic separation of spores of producers of kanamycin and tylosin]. / Elektroforeticheskoe razdelenie spor produtsentov kanamitsina i tilozina.

The stages of spore development, the most favourable for electrophoretic separation of the spores, were studied in the cultures producing kanamycin and tylosin. The stage of sporulating was shown to be the optimal. The step-by-step procedure for preparing the spores for electrophoresis is described. There were observed distinctions in the fatty acid spectrum of the cells in the cultures grown from electrophoretic fractions of the spores with different antibiotic production capacity.
