Abstract
The viability of mutant strains of Streptomyces aureofaciens (10(6) spores/ 0.2 ml) and tetracycline production remained stable for stored lyophilized spores. The same mutant produced (9375 +/- 1584) and (12336 +/- 1023) mu g/ g of tetracycline (p < 0.01), respectively for spores lyophilized in the me dia: (i) control skim milk with added sucrose and sodium glutamate, and (ii ) synthetic polyvinylpyrrolidone plus sucrose, peptone and sodium glutamate .
