Gardimycin, a new antibiotic from Actionoplanes. I. Description of the producer strain and fermentation studies.

Abstract

Two strains of Actinoplanes were isolated that produce a new peptide antibiotic named gardimycin. A detailed taxonomical study of such strains indicates that they differ between themselves and from all the described species of Actinoplanes. For this reason they are considered to be new species for which the names A. garbadinensis sp. nov. and A. liguriae sp. nov. are proposed. The type strain of A. garbadinensis is A/10889 (= ATCC 31049), the type strain of A. liguriae is A/6353 (= ATCC 31048). Studies on the medium and fermentation conditions are reported.
