sp. nov., isolated from a tidal mudflat.

A Gram-reaction-negative, aerobic, motile, rod-shaped bacterium, designated GH3-8, was isolated from rhizosphere mudflats of halophytes on the seashore of Gangwha Island, Republic of Korea. Growth was observed at pH 4-10 (optimum, pH 7-8), at 4-40 °C (optimum, 37 °C) and in the presence of 0.5-20 % (w/v) NaCl (optimum, 4 %). The predominant respiratory quinone was Q-9. The major fatty acids were C ω7, C, summed feature 3 (C ω7 and/or C ω6) and C 3OH. The polar lipids contained phosphatidylethanolamine, phosphatidylglycerol, an unidentified phosphoglycolipid, an unidentified phosphoglycoaminolipid, an unidentified glycoaminolipid, two unidentified phospholipids and two unidentified lipids. Phylogenetic analysis based on 16S rRNA gene sequences exhibited that the isolate belonged to the family , with the most closely related species, (98.1 % sequence similarity) and (97.9 %). Sequence similarity values between the isolate and other representatives of the family were all below 95.3 %. The values of average nucleotide identity between strain GH3-8 and members of the genus were 73.42 % with CCM 8464 and 72.38 % with DSM 22428. Strain GH3-8 showed digital DNA-DNA hybridization values of 18.5-18.6 % with members of the genus . Based on phenotypic and chemotaxonomic distinctiveness together with low overall genomic relatedness indices and phylogenetic data, the isolate is considered to represent a new species of the genus , for which the name sp. nov. is proposed, with the type strain GH3-8 (=KCTC 62127=NBRC 113214).
