Abstract

A novel Gram-negative, aerobic, non-motile, rod-shaped, bacterial strain (CAU 1598) was isolated from marine sand. Strain CAU 1598 grew well at 30 °C, pH 6.5–7.0 and with 3 % NaCl (w/v). Phylogeny results based on 16S rRNA gene sequencing indicated that the identified strain had the highest similarity (94.3%) to , indicating that strain CAU 1598 belongs to the family . Further, the fatty acid profile of the strain was primarily composed of C iso-C, iso-C, summed feature 3 (consisting of C 7/iso-C 2-OH) and summed feature 9 (consisting of iso-C 9 and/or C 10-methyl), with ubiquinone-8 as the major isoprenoid quinone. The polar lipid profile included diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphoglycolipid, an unidentified aminolipid and an unidentified lipid. The G+C content of the bacterial genome was 62.6 mol% and its 5.4 Mb length encompassed 144 contigs and 4236 protein-coding genes. These phenotypic, chemotaxonomic and phylogenetic data indicate that CAU 1598 belongs to a new genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain is CAU 1598 (=KCTC 82406=MCCC 1K05673).
