Devosia sediminis sp. nov., isolated from subterranean sediment

A novel Gram-negative, cream-colored, rod-shaped, aerobic, non-motile bacterium, designated MSA67 T , was isolated from a subterranean sediment sample of the Mohe Basin in Northeast China. Strain MSA67 T was detected to grow at 4–40 °C (optimum 28–30 °C), pH 5.0–10.0 (optimum, pH 7.0) and in 0.0–8.0% ( w / v ) NaCl (optimum 2.0–3.0%). Phylogenetic analysis based on 16S rRNA gene sequence revealed that strain MSA67 T was a member of the genus Devosia , with the highest similarity with D. riboflavina IFO13584 T (98.0%) and D. chinhatensis IPL18 T (97.0%). The major cellular fatty acids are C 16:0 , C 18:1 ω 7 c 11-methyl and C 18:1 ω 6 c and/or C 18:1 ω 7 c . The major polar lipids are diphosphatidylglycerol, phosphatidylglycerol, glycolipids and three unidentified phospholipids. The major respiratory quinone is ubiquinone 10 (Q-10). The genomic size of strain MSA67 T is 4.1 MB and DNA G + C content is 63.6%. Based on genotypic, phenotypic and phylogenetic results, strain MSA67 T is concluded to represent a novel species of the genus Devosia , for which the name Devosia sediminis sp. nov. is proposed. The type strain is MSA67 T (= CGMCC 1.18467 T = KCTC 82192 T ).
