Abstract

A novel Gram-positive bacterium, designated strain YIM PH21725, was isolated from a sample of rhizospheric soil of Panaxnotoginseng cultivated in Anning, Yunnan. The strain contained meso-diaminopimelic acid in the cell-wall peptidoglycan. The main fatty acids identified were C17 : 0, iso-C15 : 0, iso-C16 : 0 and C16 : 0. The main menaquinone was MK-9 (H4). The polar lipids included phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside, phosphatidylinositol, phospholipids and phospholipids of an unidentified structure containing glucosamine. The G+C content of genomic DNA was 69.43 mol%. On the basis of its 16S rRNA gene sequence, strain YIM PH21725 should belong to the genus Amycolatopsis , and was closely related to Amycolatopsis sulphurea DSM 46092 (98.57 %), Amycolatopsis jejuensis JCM13280 (97.27 %), Amycolatopsis jiangsuensis KCTC 19885 (96.88 %) and Amycolatopsis ultiminotia JCM 16989 (96.8 %). The phenotypic, chemotaxonomic, phylogenetic and digital DNA–DNA hybridization results clearly indicated that strain YIM PH21725 represents a novel species of the genus Amycolatopsis , for which the name Amycolatopsis panacis sp. nov. is proposed. The type strain is YIM PH21725 (=CCTCC AA 2017044=KCTC 49031=DSM 105902).
