Abstract The viability of mutant strains of Streptomyces aureofaciens (106 spores/0.2ml) and tetracycline production remained stable for stored lyophilized spores. The same mutant produced (9375±1584) and (12336±1023) μg/g of tetracycline (p〈0.01), respectively for spores lyophilized in the media: (i) control skim milk with added sucrose and sodium glutamate, and (ii) synthetic polyvinylpyrrolidone plus sucrose, peptone and sodium glutamate.
