The optimum culture conditions for an antibiotics from Actinomyces sp. were investigated. The optimum composition of medium for antibiotics production was 1% glucose, 1% soybean meal, 0.5% NaCl, 0.1% , and the optimum initial pH was 7.0. And the antibiotics showed highest activity when the strain isolated from soil was aerobically cultivated at for 72hours under the optimum conditions. A production of the antibiotics from Actinomyces sp. begins at the 36th hours and then reached the maximum at the stationary phase developed at the 72th hours under the optimum conditions.
