title: Production of deoxyfrenolicin and a new antibiotic, frenolicin B by Streptomyces roseofulvus strain AM-3867.
abstract: Two antibiotics of frenolicin group, antibiotic AM-3867 I and II were isolated from the fermentation broth of Streptomyces roseofulvus strain No. AM-3867, a soil isolate. The former was a new antibiotic designated as frenolicin B and its structure containing gamma-lactone was determined, while the latter was identified as deoxyfrenolicin having been chemically prepared from frenolicin.
