Actinomadura oligospora sp. nov., the Producer of a New Polyether Antibiotic

Abstract

A new species of Actinomadura, which was isolated from soil collected in India, is characterized by sparse aerial mycelia, yellowish gray to brown vegetative mycelia, a carbohydrate utilization pattern of adonitol, cellobiose, glucose, and ribose, unique physiological characteristics, and the production of a new polyether antibiotic. Whole cells contain meso-diaminopimelic acid and madurose, but do not contain nitrogenous phospholipids or mycolic acids. The name proposed for this new species is Actinomadura oligospora, and the type strain is strain A80190.1 (= NRRL 15878).
