title: Microbiological 1,2-dehydration of microcrystalline epihydrocortisone and its 21-acetate.
abstract: A method is described for obtaining epiprednisolone and its 21-acetate by means of microbiological 1,2-dehydration by a culture of Mycobacterium globiforme 193. The substrate, epihydrocortisone or its 21-acetate, is added in the form of a microcrystalline suspension at a concentration of 25-100 g/liter medium.
