title: [Effect of several compounds on the process of reduction of the 20-keto group of corticosteroids by a culture of Mycobacterium globiforme].
abstract: The effect of certain metabolites produced in the metabolism of carbohydrates, proteins and fats on the reduction of the 20-keto group in a number of corticosteroids (prednisone, prenisolone, 6 alpha-methylprednisolone) was studied with the culture of Mycobacterium globiforme. The metabolites and inhibitors of the respiration chain were found to stimulate the 20 beta-reduction of a steroid molecule. The inhibitor of oxidative phosphorylation, 2,4-dinitrophenol, inhibited the reduction of the 20-keto group in a steroid.
