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

Abstract

Two strains of Actinoplanes have been 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 nov. sp. and A. liguriae nov. sp. 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.
