Abstract
The addition of elemental sulfur to the fermentation of Streptomyces sioyaensis in a soybean meal medium resulted in a three- to fourfold increase of siomycin. Further experiments on the effect of elemental sulfur during fermentation suggest that one of the key steps stimulating siomycin synthesis is the utilization of thiosulfate, which accumulates in the medium as the result of the oxidation of elemental sulfur.
