Abstract

In this study, strain YIM 65004, isolated from roots of , was shown to represent a novel species of the genus by means of a polyphasic approach. Chemotaxonomic data gathered for peptidoglycan type, menaquinones, phospholipids and fatty acids strongly supported the classification of this strain within the genus : the cell-wall peptidoglycan contained lysine, glutamic acid, alanine, glycine and aspartic acid, the predominant menaquinones were MK-8(H) (66.97 %) and MK-7(H) (23.26 %), the phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and an unknown ninhydrin-negative phospholipid, and the major cellular fatty acids were anteiso-C (61.98 %), iso-C (14.25 %) and iso-C (13.04 %). The G+C content of the genomic DNA was 71.7 mol%. A number of physiological features were found that clearly distinguished strain YIM 65004 from recognized species. DNA–DNA hybridization studies suggested that the novel strain represents a separate genomic species. Based on the above data, a novel species of the genus , sp. nov., is proposed, with the type strain YIM 65004 (=CCTCC AA 208060=DSM 21948).
