Sneathiella sedimenti sp. nov., isolated from marine sediment.

A novel bacterium, designated CAU 1612 T , was isolated from coastal sediment sampled in the Republic of Korea. Cells of the strain were Gram-stain-negative, rod-shaped and motile. Optimum growth occurred at 30 °C, at pH 7.0 and with 1.0 % (w/v) NaCl. Based on 16S rRNA gene sequences, phylogenetic analysis revealed that strain CAU 1612 T belonged to the genus Sneathiella and showed highest similarity to ' Sneathiella litorea ' JCM 33810 T (98.5 %), followed by Sneathiella chungangensis KCTC 32476 T (97.7 %), Sneathiella aquimaris KCTC 12842 T (96.0 %), Sneathiella chinensis LMG 23452 T (95.5 %), Sneathiella limimaris KCTC 52846 T (95.5 %) and Sneathiella glossodoripedis KCTC 12842 T (95.4 %). The average nucleotide identity and digital DNA-DNA hybridization values of strain CAU 1612 T were estimated to be 68.5-81.7 % and ≤23.7 %, respectively, to members of the genus Sneathiella . The DNA G+C content was 54.1 mol%. The major cellular fatty acids (>10 %) were C 16:0 , C 19 : 0 cyclo ω 8 c and summed feature 8 (C 18 : 1  ω 7 c and/or C 18 : 1  ω 6 c ). The major menaquinone was Q-10 and the predominant polar lipids were phosphatidylmethylethanolamine, phosphatidylethanolamine and phosphatidylglycerol. On the basis of taxonomic evidence, strain CAU 1612 T represents a novel species, for which the name Sneathiella sedimenti sp. nov. is proposed. The type strain is CAU 1612 T (=KCTC 82427 T =MCCC 1K06082 T ).
