Amycolatopsis xylanica sp. nov., isolated from soil
An actinomycete, designated CPCC 202699T, was isolated from soil in Qinghai province, China, and its taxonomic status was established. Strain CPCC 202699T 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(H4) as the predominant menaquinone and iso-C16 : 0 (18.8 %), iso-C15 : 0 (18.1 %), iso-C14 : 0 (14.2 %), C16 : 1 cis9 (10.9 %) and C17 : 1 cis9 (10.3 %) as the major fatty acids. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 202699T formed a separate branch within the genus Amycolatopsis. However, strain CPCC 202699T 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 202699T, a novel species, Amycolatopsis xylanica sp. nov., is proposed. The type strain is CPCC 202699T (=DSM 45285T =KCTC 19581T =CCM 7627T).
