Abstract

Three phosphonic acid antibiotics were found to be produced in the fermentation broths of Streptomyces. FR-31564 and FR-32863 were produced by Streptomyces lavendulae. FR-33289 was produced by a strain of Streptomyces, identified as Streptomyces rubellomurinus subsp. indigoferus. They are distinct from, but resemble FR-900098 which was reported in our preceding paper, in their chemical and biological characteristics.
