Abstract

12-Deoxy-cardiac glycosides or their aglycones (e.g. digitoxin) are converted to 12 beta -hydroxy derivatives (e.g. digoxin and 7 beta -hydroxydigoxin) by contacting under aerobic conditions with a culture of Streptomyces praecox MNG 127. (MNG = Hungarian National Collection of Microorganisms, Budapest).
