title: Pontibacter populi sp. nov., isolated from the soil of a Euphrates poplar (Populus euphratica) forest.
abstract: A Gram-negative-staining, rod-shaped, non-motile and pink bacterial strain was isolated from the soil of a Populus euphratica forest located in Xinjiang, China. The strain, designated strain HYL7-15(T), was subjected to a taxonomic analysis using a polyphasic approach. 16S rRNA gene sequence analyses indicated that the isolate belonged to the phylum Bacteroidetes and was related to the genus Pontibacter, with sequence similarities ranging from 93.1 to 95.0% with other species of the genus Pontibacter. Strain HYL7-15(T) contained MK-7 as the predominant menaquinone and its DNA G+C content was 44.9 mol%. The major cellular fatty acids of the novel strain were iso-C(15:0) (16.49%), iso-C(17:0) 3-OH (10.96%) and summed feature 4 (comprising anteiso-C(17:1) B and/or iso-C(17:1) I, 18.46%). The major polar lipids were phosphatidylethanolamine (PE) and phosphatidylglycerol (PG); diphosphatidylglycerol (DPG), three unknown aminophospholipids (APLs) and two unknown phospholipids (PLs) were also detected. On the basis of the evidence presented, it is concluded that strain HYL7-15(T) represents a novel species of the genus Pontibacter, for which the name Pontibacter populi sp. nov. is proposed. The type strain is HYL7-15(T) (=CCTCC AB 206239(T)=NRRL B-59488(T)).
