Abstract
A novel actinobacterium, designated strain NEAU-yn17T, was isolated from a soil sample collected at the wastewater discharge site of a pesticide factory in Harbin, northern China, and characterized using a polyphasic approach. Morphological and chemotaxonomic properties of strain NEAU-yn17T were consistent with the description of the genus Saccharothrix , such as the spore arrangement, the diamino acid of the peptidoglycan, the whole-cell hydrolysates, the predominant menaquinone and the phospholipid profile. Phylogenetic analysis based on 16S rRNA gene sequences demonstrated that strain NEAU-yn17T should also be classified in the genus Saccharothrix , with Saccharothrix saharensis DSM 45456T (99.52 % sequence similarity) and Saccharothrix xinjiangensis JCM 12329T (99.04 %) as the nearest phylogenetic relatives. A combination of DNA–DNA hybridization results and some phenotypic characteristics indicated that strain NEAU-yn17T can be distinguished from its closest relatives. Therefore, strain NEAU-yn17T represents a novel species of the genus Saccharothrix , for which the name Saccharothrix carnea sp. nov. is proposed. The type strain is NEAU-yn17T ( = CGMCC 4.7097T = DSM 45878T).
