Characterization of a new antibiotic of iturin group: Bacillomycin D

Abstract

The characterization of an antibiotic isolated from a strain of Bacillus subtilis revealed that this compound is a new antifungal antibiotic of the iturin group. It contains a lipid moiety which is a mixture of 3-amino 12-methyl tridecanoic acid (40%) and 3-amino 12-methyl tetradecanoic acid (60%) and a peptide moiety: L-Aspi, D-Aspi, L-G1U, L-PrO1, D-Seri, L-Thr1. and D-Tyr1 These two moieties are joined by a threonyl-β-aminoacic linkage. © 1980, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
