TWO NEW SPECIES OF THE GENUS KITASATOSPORIA, KITASATOSPORIA PHOSALACINEA SP. NOV. AND KITASATOSPORIA GRISEOLA SP. NOV.

Abstract

Two new species of the genus Kitasatosporia are described, for which the names Kitasatosporia phosalacinea and Kitasatosporia griseola are proposed. The former produces a new peptide antibiotic, phosalacine, and the latter produces a known antibiotic, setamycin. As in K. setalba, the type species of Kitasatosporia, the aerial and submerged spores of two the new strains contain LL-2, 6-diaminopimelic acid (A₂pm), while the vegetative and filamentous mycelia contain meso-A₂pm. The type strain of K. phosalacinea is strain KA-338 (IFO 14372, JCM 3340) and that of K. griseola is strain AM-9660 (IFO 14371, JCM 3339).
