Abstract

Incubation of testosterone, androstenedione and progesterone with Cladosporium cladosporioides MRC 70282 for 5 days is reported. Testosterone was hydroxylated at C-16ß and then oxidised at C-16. This was accompanied by a minor independent oxidation at C-17 and epimerisation at C-17. Androstenedione was reduced at C-17 and hydroxylated at C-16ß, and this was then oxidised to a ketone at C-16. This was accompanied by a minor epimerisation at C-17. Progesterone was hydroxylated at C-21, and this was accompanied by a minor independent 5a-reduction. [ABSTRACT FROM AUTHOR]
