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 degrees C (optimum 28-30 degrees 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 omega 7c 11-methyl and C-18:1 omega 6c and/or C-18:1 omega 7c. 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)).
