title: Two novel microbial conversion products of progesterone derivatives.
abstract: Two novel microbial steroid hydroxylations were found in a screening of 131 microorganisms under aerobic conditions. 17 alpha-Hydroxyprogesterone was hydroxylated in the 8 beta-position by Corynespora melonis CBS 16260, and fermentation of 17 alpha-acetoxyprogesterone with Pycnosporium species ATCC 12231 yielded 11 beta-hydroxy- and 11 beta, 12 beta-dihydroxy-17 alpha-acetoxyprogesterone. The known 11 beta-hydroxy compound could be obtained as a single product with Trichothecium roseum ATCC 12519.
