Abstract

The actinomycete strain YIM 90462 was isolated from a salt mine sample collected from Yunnan province, south-west China. Comparative 16S rRNA gene sequence analysis demonstrated that the isolate, which had sequence similarities of more than 97 % to , and , was a candidate member of the genus . Subsequently, a polyphasic approach was used to clarify the taxonomic position of strain YIM 90462. Its diagnostic diamino acid was -diaminopimelic acid and whole-cell sugars contained galactose, xylose and glucose. The predominant menaquinones were MK-10(H) and MK-10(H). The major fatty acids were iso-C and anteiso-C. Results of DNA–DNA hybridizations and physiological and biochemical tests enabled genotypic and phenotypic differentiation of strain YIM 90462 from the three species with validly published names. Consequently, it is proposed that strain YIM 90462 should be recognized as a representative of a novel species of , sp. nov. The type strain is YIM 90462 (=KCTC 19123 =DSM 44931). In addition, an emended description of the genus is presented.
