Myxochelin a, a new iron-chelating compound from angiococcus disciformis (myxobacterales). Production, isolation, physico-chemical and biological properties

Abstract

Myxochelin A, a new catechole siderophore, was isolated from the culture broth of the myxobacterium, Angiococcus disciformis strain An d30. As is the case with other iron-chelating compounds the production of myxochelin A could be markedly increased up to 44 mg/liter by fermentation at low iron concentrations (10-7 M FeCl3). The new substance showed weak activity against some bacteria. © 1989, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION. All rights reserved.
