Abstract

Two strains, designated 2251T and 3058, that were aerobic, Gram-stain-negative, non-motile, coccoid or short rod-shaped bacilli, have recently been isolated from Tibetan antelopes on the Qinghai-Tibet Plateau. The results of phylogenetic analyses of 16S rRNA gene sequences indicated that strains 2251T and 3058 represent a new species within the genus Paracoccus and are most similar to ‘ Paracoccus gahaiensis ’ CUG00006T (98.9 and 99.3 %), Paracoccus nototheniae I-41R45T (98.3 and 98.7 %) and Paracoccus hibiscisoli THG-T2.31T (97.6 and 97.8 %). Results of genomic sequence-based phylogenomic analysis agreed with those from 16S rRNA gene sequence analysis. Optimal growth was achieved at pH 7.0–7.5 and 28 °C with marine medium. Cells contained C18 : 1 ω7c as the major cellular fatty acid and ubiquinone-10 as the predominant menaquinone. The polar lipids comprised phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, phospholipid, glycolipid and an unidentified lipid. The cell-wall peptidoglycan amino acids were meso-2,6-diaminopimelic acid, alanine and glutamic acid; the major cell-wall sugar was galactose. The G+C content of strain 2251T was 66.5 mol%. Both strains (2251T and 3058) had DNA–DNA relatedness values less than 50 % with all available genomes of the genus Paracoccus in the ncbi database. Differential genotypic inferences, together with phenotypic and biochemical characteristics, demonstrated that strains 2251T and 3058 should be classified as a novel species of the genus Paracoccus , for which the name Paracoccus liaowanqingii sp. nov. is suggested. The type strain is 2251T (=CGMCC 1.16490T=DSM 106269T).
