Studies on Streptomycetes

Motoo Shibata; Eiji Higashide; Toshihiko Kanzaki; Hiroichi Yamamoto; Koiti Nakazawa

Investigation was made on the mycological and antibacterial properties of a strain No. 46408 isolated from a soil sample collected in Shimoueda, Wakayama Prefecture. The strain No. 46408 was compared with similar strains, St. hygroscopicus and St. halstedii, and it was judged to belong to a new species and therefore named Streptomyces atratus nov. sp. Also a strain A-165-Z1, which produces ilamycin, was referred to on its mycological properties and assumed to resemble St. atratus. St. atratus was found to produce new antibiotics, rufomycin A and B, specially active against acid-fast bacteria.
