Abstract
A Gram stain-negative, aerobic, motile by gliding, rod-shaped bacterial strain CAU 1569T was isolated from marine sediment on Shido Island in Incheon. It grew at 20-37 °C (optimum, 30 °C), pH 6.0-9.0 (optimum, 7.0), 2-6% NaCl (w/v) (optimum, 2%). Phylogenetic analysis based on 16S rRNA gene sequence indicated that strain CAU 1569T formed a distinct lineage with only the type strain of Snuella. Strain CAU 1569T showed high similarity to S. lapsa KACC 14152T (95.8%), Mariniflexile gromovii KMM KCTC 12570T, Aestuariibaculum marinum KCTC 52521T (95.4%), A. suncheonense KACC 16186T (94.6%) and Yeosuana aromativorans KCCM 42019T (94.4%). The genome contained 57 contigs, 3,437 protein-coding gene, 3 rRNAs (5, 16, and 23S), 43 tRNAs, and with a 35.7 mol% G + C content. The DDH value between strain CAU 1569T and S. lapsa KACC 14152T was 39.4 ± 0.6%. The only isoprenoid quinone was menaquinone 6 (MK-6). The major fatty acids were iso-C15:0, C15:1-iso G, and C17:0 iso 3-OH. Strain CAU 1569T contained diphosphatidylglycerol, aminoglycolipid, unidentified aminolipid, and three unidentified lipids. Based on phylogenetic, genomic, physiologic, and chemotaxonomic characterizations, strain CAU 1569T represents a novel Snuella species, which the name Snuella sedimenti sp. nov. is proposed. The type of strain is CAU 1569T (= KCTC 82409T = MCCC 1K05670T).
