Abstract
The present invention is directed to a process for producing frenolicin B. The process comprises fermenting a broth so as to produce frenolicin, said broth having a microorganism capable of producing frenolicin. The frenolicin is then converted in the broth under anaerobic conditions to deoxyfrenolicin. The deoxyfrenolicin is converted to frenolicin B.
