title: Metabolism of 17-hydroxyprogesterone by a Bacillus species.
abstract: Fermentation of 17-hydroxyprogesterone with a Bacillus species (IICB-301) in a modified nutrient medium under aerobic conditions yielded androst-4-ene-3,17-dione and 15 alpha,17-dihydroxypregn-4-ene-3,20-dione in addition to a new pregnane analogue, 6 beta,17,20 alpha-trihydroxypregn-4-ene-3-one. Each microbial metabolite was characterized by the application of various spectroscopic techniques. The availability of the new metabolite, 6 beta,17,20 alpha-trihydroxypregn-4-ene-3-one, enabled complete elucidation of its 13C-n.m.r. spectrum.
