Abstract
Strain YIM B00363T, a Gram-positive, aerobic, non-motile, rod-shaped, spore-forming bacterium, was isolated from saline soil samples collected from a salt lake in Xinjiang province, north-west China, and was characterized using a polyphasic approach. The optimum growth temperature was 37 °C and the optimum pH was 7.5–8.0. The major menaquinone was MK-7; anteiso-C15:0 (53.52%), iso-C15:0 (15.04%) and C16:0 (12.76%) were the predominant cellular fatty acids. The diagnostic diamino acid of the cell wall peptidoglycan was meso-diaminopimelic acid. The phospholipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, unidentified phospholipids, unidentified glycolipids and unknown lipids. The DNA G + C content of the type strain was 50.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain YIM B00363T belonged to a cluster comprising species of the genus Paenibacillus. The nearest relatives were P. residui MC-246T and P. senegalensis JC66T, with 93.2% and 92.8% gene sequence similarities, respectively. On the basis of its phenotypic characteristics and phylogenetic distinctivenes, strain YIM B00363T represents a novel species of the genus Paenibacillus, for which the name Paenibacillus turpanensis sp. nov. is proposed. The type strain is YIM B00363T (= CGMCC 1.17507T = KCTC 43184T).
