title: Progesterone side-chain cleavage by Bacillus sphaericus.
abstract: The side-chain of progesterone was cleaved by Bacillus sphaericus to produce two C-19 keto androstene steroids. The structures of these metabolites were androstenedione and 1-dehydroandrostenedione. High concentrations of glucose in the culture medium inhibited conversion of progesterone to these two metabolites.
