In the course of various fermentations for the production of antibiotics by Streptomyces sp., glycerol, as well as glucose, has been found to be a preferred carbon source. In order to determine glycerol in the fermentation broth, a colorimetric method based on the procedures described by West was modified with respect to the condition of oxidation of glycerol by periodic acid. It has been found that, under a mild condition of periodic acid oxidation at 0 ℃ for 30 min, glycerol can be determined even when glucose is present. This method was applied in the practical production of three antibiotics : cycloserine, echinomycin, and streptomycin, and the following results were obtained : (1) The metabolism of glycerol was more active than that of glucose or starch; during each fermentation, the glycerol in the medium was nearly consumed after 45 hours.(2) The peak of antibiotic production in fermented broth appeared after the glycerol consumption was completed.
