ABSTRACT
An actinomycin-D producing strain was isolated from soil and characterized as Streptomyces sindenensis. The culture was subjected to UV irradiation and a mutant with 400 percent higher actinomycin-D production was isolated (400 mg/l-1 as compared to 80 mg/l-1 produced by the parent). Production medium was optimized and antibiotic yield with the mutant was enhanced to 850 mg/l-1 which is 963 percent higher as compared with the parent.
RESUMO
Uma cepa produtora de actinomicina-D foi isolada de solo e caracterizada como Streptomyces sindenensis. A cultura foi submetida à radiação UV, e um mutante capaz de produzir 400 por cento mais actinomicina-D foi isolado (400mg/L comparado a 80mg/L produzido pela cepa parental). O meio de produção do antibiótico foi otimizado e o rendimento aumentou para 850 mg/L, ou seja, 963 por cento mais alto que a cepa parental.
