Résumé

A novel bacterium, strain QS115 T , was isolated from deep-sea sediment collected from the South China Sea at a depth of 1151 m. Phylogenetic analyses based on 16S rRNA gene sequences indicated that QS115 T was most closely related to Parasedimentitalea marina W43 T , with similarity of 98.21 %. Strain QS115 T shared 82.39 % average nucleotide identity, 26.3 % digital DNA–DNA hybridization and 85.32 % average amino acid identity with P. marina W43 T . Cells of strain QS115 T were Gram-stain-negative, rod-shaped and grew optimally at 10 °C, pH 7.5 and 2 % (w/v) NaCl. The principal fatty acids were summed feature 8 (C 18 : 1 ω 7 c / ω 6 c ), the major respiratory quinone was ubiquinone-10 and predominant polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, glycophospholipid, phosphatidylglycerol and phosphatidylcholine. Polyphasic analyses of physiological and phenotypic characteristics and genomic studies suggested that strain QS115 T represents a novel species of the genus Parasedimentitalea , for which the name Parasedimentitalea psychrophila sp. nov. is proposed (type strain QS115 T =MCCC 1K04395 T =JCM 34219 T ).
