Hydrocortisone and prednisolone transformation by Arthrobacter globiformis cells in aerobic and anaerobic conditions was studied. 3-Ketosteroid-1-en-dehydrogenase activity was shown to be the major factor regulating the direction of transformation. When it is high (aerobic conditions), the end products of hydrocortisone transformation are prednisolone or its 20 beta-hydroxy derivative. The latter is produced via 1-en-dehydrogenation, which is not a limiting stage of the process. Low 3-ketosteroid-1-en-dehydrogenase activity (in the presence of cyanide) or its complete inhibition (strictly anaerobic conditions) result in the direct reduction of 20-keto group of hydrocortisone.
