title: Progesterone side-chain degradation beside hydroxylation with Rhizopus nigricans depends on the presence of nutrients.
abstract: In the absence of nutrients, Rhizopus nigricans transforms progesterone into a mixture of 11 alpha-hydroxy-4-androstene-3,17-dione and 11 alpha-hydroxy-1,4-adrostadiene-3,17-dione. The same mixture is obtained by the transformation of testosterone and its acetate.
