説明

The optimun conditions in shake culture for the production of the open-ring acid of spiculisporic acid by Penicillium spiculisporum No. 10-1 were examined. The best growth of the strain was observed at 36℃, but the best acid production was at 30℃. The optimum pH for the acid production was extremely low, 2 or below. Either higher concentrations of glucose or lower rates of aeration led to a decrease in acid yield with formation of considerable amounts of ethanol. Intermittent feeding of glucose improved acid production. The amounts of the acid acumulated in the culture broth reached more than 110 g per l after 10 days; the yield of the acid amounted to about 40% on the weight basis of glucose consumed, this value corresponding to more than 60% of carbon recovery.
