Transformations of Cardio-active Steroids by Microorganisms

Yoshio Nozaki

Hydroxylation of digitoxigenin with Absidia orchidis resulted in the formation of 1β-hydroxydigitoxigenin (βacovenosigenin A), 5β-hydroxydigitoxigenin (βperiplogenin), 7β-hydroxydigitoxigenin, 1β,7β-dihydroxydigitoxigenin and 5β,7β-dihydroxydigitoxigenin. This is probably the first example of microbial 1β-hydroxylation of steroid.
