Abstract

NEW MATERIAL:Antibiotic substance AC-69. Appearance, white powder: melting point, 206W208°C (decomposition); elemental analysis, C 53.45%, H 7.25%, N 11.93%, O 26.20%; constituent amino acids determined by acid hydrolysis, aspartic acid, thereonine, serine, glutamic acid and a novel amino acid; molecular weight, 1076 (as a dibasic acid, determined by titration); optical rotation, [α]D20=-45.4° (C=1.06 methanol).
USE: Fungicide for agricultural and horticaltural use, having specific inhibitory activity to pathogenic fungi.
PROCESS: For example, Streptomyces AC-69 strain (FERM-P No.4607) is aerobically cultured, and the objective substance is extracted from the filtrate of the medium or from the microbial cells. The substance is purified by a combination of adsorption chromatography, ion exchange chromatography, etc. to obtain pure AC- 69 substance.
