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.

Two new products: 9,10-seco-1,3,5(10)-pregnatrien-3,17 a-dihydroxy-9,20-dione and 9,10-seco-1,3,5(10)-pregnatrien-3,17a,20-triol-9-one, have been isolated as 17 α-hydroxyprogesterone transformation products fromNocardia DSM 43298. The structures were established by spectroscopic methods.
