Abstract

PURPOSE: To prepare cephamycin C by the fermentation method, by cultivating a specific species belonging to the genus Streptomyces in a culture medium, and collecting the resultant produced and accumulated cephamycin C.
CONSTITUTION: A new species Streptomyces sp. AMA8-2 (FERM-P No. 5959) belonging to actinomyces is cultivated in a culture medium usually used for the cultivation of the actinomyces at a pH adjusted to about 6.5W7.0 and a cultivation temperature of 20W30°C for 48W96hr by the spinner culture method with aeration to produce and accumulate cephamycin C. The resultant cephamycin C is then separated and purified by the conventional method to give the aimed cephamycin C with ease.
