Abstract:
An actinomycete, designated CPCC 202699(T), was isolated from soil in Qinghai province, China, and its taxonomic status was established. Strain CPCC 202699(T) contained meso-diaminopimelic acid in its peptidoglycan, arabinose and galactose as the diagnostic sugars in whole-cell hydrolysates, a phospholipid pattern consisting mainly of phosphatidylethanolamine, phosphatidylmethylethanolamine and phosphatidylcholine, MK-9(H(4)) as the predominant menaquinone and iso-C(16 : 0) (18.8 %), iso-C(15 : 0) (18.1 %), iso-C(14 : 0) (14.2 %), C(16 : 1) cis9 (10.9 %) and C(17 : 1) cis9 (10.3 %) as the major fatty acids. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 202699(T) formed a separate branch within the genus Amycolatopsis. However, strain CPCC 202699(T) showed low 16S rRNA gene sequence similarities (<97.0 %) with type strains of species with validly published names in the genus Amycolatopsis. On the basis of genotypic and phenotypic differences from the closest phylogenetic neighbours of strain CPCC 202699(T), a novel species, Amycolatopsis xylanica sp. nov., is proposed. The type strain is CPCC 202699(T) (=DSM 45285(T) =KCTC 19581(T) =CCM 7627(T)).
