Notes:
During investigations of submerged fermentation of penicillin and chlortetracycline, we reached the conclusion that production in relation to oxygen transfer is relatively uninfluenced by the composition of the fermentation medium. The maximum penicillin production, using the strain Penicillium chrysogenum NG in flasks on a shaker was uniformly achieved in all investigated media with an oxygen transfer rate of 0.81; and in chlortetracycline, using strain Streptomyces aureofaciens BMK-11, with an oxygen transfer rate of 0.59 ml. O2/ml./hour. The primary factor which influences the antibiotics production is the transfer of oxygen into the liquid. The absolute volume of production is, however, partly influenced by mechanical conditions of fermentation and the composition of the medium.
