Abstract

The production of doxorubicin by a mutant of Streptomyces peucetius subsp. caesius was studied. The optimal culture conditions, such as inoculum size and medium composition were established to improve the productivity of doxorubicin. The optimal medium composition was found to be 4% maltose, 0.5% HEPES, 0.02% $K_2HPO_4$, 0.01% $MgSO_4$. As an antiform agent, 0.001% KG(10% Adekanol+10% Silicone) was suitable one among various agents. Culture was carried out in 2.5 L jar-fermenter with different aeration rates of 1.5, 1.0, and 1.5 v/v min. The maximum production of doxorubicin(29 mg/l) was obtained at 1.5 v/v min of aeration rate, and even at 1.0 v/v min, the production of doxorubicin was increased up to 15% compared with that of shake-flask culture.
