Capuramycin, a new nucleoside antibiotic taxonomy, fermentation, isolation and characterization

Abstract

A new antibiotic capuramycin was isolated from the culture filtrate of Streptomyces griseus 446-S3 by adsorption and partition column chromatography. Based on its chemical structure being an uracil nucleoside with a caprolactam substituent, this substance was named as capuramycin. This paper describes the taxonomy of a producing organism, fermentation, isolation, characterization and biological properties of capuramycin. © 1986, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
