Notes:
A method has been devised for the estimation in fermentation media, of 1-dehydro-17-α-methyltestosterone in the presence of 17-α-methyltestosterone. This method involves the extraction of the steroids with chloroform, and spectrophotometric measurement of the chromogen formed by a specific color reaction with sulfuric acid and 1-dehydro-17-α-methyltestosterone. The fermentation liquor and 17-α-methyltestosterone do not interfere. With this rapid (30 min.) method, quantitative tests on the progress of the steroid transformation can be made at frequent intervals during one fermentation run, these tests yielding the necessary information for an adequate control of the optimum conditions of production.
