Clostridiumparaputrificum D 762-06 was found to contain an NADP-dependent 12 beta-hydroxysteroid dehydrogenase, already present in uninduced cells. Its specific activity could, however, be enhanced up to about 3-fold by the inclusion of bile acids with a 12-keto group or a 12 beta-hydroxy group in the growth medium. 3 alpha-Hydroxy-12-keto-5 beta-cholanoic acid was the most effective inducer.
