ABSTRACT
A halotolerant actinomycete strain, designated XHU 5031(T), was isolated from a salt lake in Xinjiang Province, northwest China. Its taxonomic status was determined using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the organism was most closely related to Myceligenerans xiligouense DSM 15700(T) (98.4 %), Myceligenerans halotolerans XJEEM 11063(T) (98.0 %) and Myceligenerans crystallogenes DSM 17134(T) (97.5 %). However, it had relatively low values for DNA-DNA relatedness with the above strains (46.2, 39.4 and 36.5 %, respectively). The peptidoglycan type was A4α. This organism contained glucose, mannose and galactose as the major whole cell sugars. The predominant menaquinone was MK-9(H(4)). The major fatty acids were iso-C(150,) anteiso-C(150) and iso-C(160). The polar lipids detected were diphosphatidylglycerol (DPG), phosphatidylglycerol (PG), phosphatidylinositol (PI), one unknown phospholipid (PL) and two unknown glycolipids (GL). The G+C content of genomic DNA was 71.2 mol %. Phenotypic data clearly distinguished the isolate from its closest relatives. The combined genotypic and phenotypic data indicated that the isolate XHU 5031(T) represented a novel species of the genus Myceligenerans. The proposed name for this organism is Myceligenerans salitolerans sp. nov., with type strain XHU 5031(T) (=KCTC 29128(T) = CCTCC AB 2012908(T)).
