  • Title: [Study of the population makeup and antibiotic and transamidinase activity of Actinomyces streptomycini 773 stored for a long period in a lyophilized, dried state].
    Author: Kuznetsov VD, Bushueva OA, Rodionova EG.
    Journal: Antibiotiki; 1975 Jan; 20(1):15-8. PubMed ID: 1122123.
    Abstract:
    Studies on variation of the streptomycin-producing organism Act. streptomycini 773 on its storage in lyophilized state showed that prolonged maintenance (for 8 years) resulted in increased percentage of "oligospore" (up to 6.9 per cent) and asporogenic (up to 6.0 per cent) variants in the population. The variants had lower transamidinase and antibiotic activity.
