Sediminibacterium soli sp. nov., isolated from soil

A Gram-stain-negative, facultative anaerobic strain, designated WSJ-3 T , was isolated from soil. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain WSJ-3 T belongs to genus Sediminibacterium and exhibits the highest sequence similarities to Sediminibacterium roseum SYL130 T (97.0%), Sediminibacterium goheungense DSM 28323 T (96.9%), Sediminibacterium aquarii AA5 T (96.7%), and Sediminibacterium salmoneum NBRC 103935 T (95.2%). The average nucleotide identity values of strain WSJ-3 T / S . roseum SYL130 T and strain WSJ-3 T / S . goheungense DSM 28323 T are 72.2% and 70.4%, respectively, and digital DNA–DNA hybridization values for these are 19.2% and 19.1%, respectively. Strain WSJ-3 T has a genome size of 3.88 Mb, with a DNA G + C content of 50.1 mol% and comprises of 3263 predicted genes. A phylogenetic tree constructed using the genomic core protein coding sequences revealed that strain WSJ-3 T clusters with S . roseum SYL130 T . Strain WSJ-3 T has menaquinone-7 as the only respiratory quinone and phosphatidylethanolamine, three unidentified phospholipids, four unidentified aminophospholipids, two unidentified aminolipids, and three unidentified lipids as the polar lipids. The major fatty acids of strain WSJ-3 T are iso-C 15:0 , iso-C 17:0 3-OH, and iso-C 15:1 G. On the basis of the polyphasic results, the isolate represents a novel species of the genus Sediminibacterium , for which the name Sediminibacterium soli sp. nov. is proposed. The type strain is WSJ-3 T (= KCTC 72839 T = CCTCC AB 2019408 T ).
