CHLOROPOLYSPORINS A, B AND C, NOVEL GLYCOPEPTIDE ANTIBIOTICS FROM FAENIA INTERJECTA SP. NOV.

I. TAXONOMY OF PRODUCING ORGANISM

Abstract

Strain SANK 60983, an actinomycete isolated from a soil sample, was found to produce the new glycopeptide antibiotics, chloropolysporins A, B and C. Short chains of spores occur in the both aerial and substrate hyphae. meso-Diaminopimelic acid is present in the cell wall and galactose and arabinose in the whole-cell hydrolysate. Mycolic acid is absent. On the basis of the morphological, cultural and physiological characteristics, this strain was determined to be a new species of Faenia designated Faenia interjecta sp. nov. The type strain of F. interjecta Okazaki and Enokita is SANK 60983.
