실험 절차

100 ml of the medium of Example 1 were inoculated with Mucor hiemalis FERM P-3800 and shaken at 26.5° C. for 22 hours. The culture was then treated with 50 mg of 17β-hydroxy-4-androsten-3one in 1 ml of dimethyl sulphoxide and incubated for 8 days. There were obtained from the culture filtrate 4.8 mg of 7α,17β-dihydroxy-4-androsten-3-one of melting point 191°-193° C.
