Abstract
The taxonomy of a soil isolate, strain MK27-91F2 which produced a new antifungal antibiotics formamicin, was studied. We propose that the strain should belong to a new species of the genus Saccharothrix with the new name Saccharothrix tangerinus sp. nov., the type strain being MK27-91F2 (= JCM 10302 = IFO 16184 = FERM P-16053). This new species was characterized by a type III cell wall, galactose and rhamnose as whole-cell sugars, type PII phospholipids, MK-9(H4) menaquinone, fatty acid components of i-16:0, i-14:0, i-15:0, 16:0, 16:1, 17:1 and i-16:1, but lacking mycolic acids, a G+C content in DNA of 74 mol %, and a base sequence of 16S ribosomal RNA gene.
