title: Marimonas arenosa gen. nov., sp. nov., isolated from sea sand.
abstract: A Gram-stain-negative, non-motile, non-spore-forming, aerobic and short rod-shaped bacterial strain, CAU 1311T, was isolated from sea sand in the Republic of Korea. Strain CAU 1311T grew at temperatures from 20-37 °C, in the range of pH 6.5-10.0, and under various NaCl concentrations from 0-6 % (w/v). Phylogenetic analysis based on the 16S rRNA gene sequence of CAU 1311T showed that it formed a distinct lineage within the family Rhodobacteraceae as a separate deep branch, with 96.2 % or lower sequence identity to representatives of the genera Marivita, Aestuariivita, Mameliella, Sulfitobacter and Maritimibacter. The major fatty acid was C18  : 1ω7c and the predominant respiratory quinone was Q-10. The major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified aminolipid and an unidentified glycolipid. The DNA G+C content was 60.7 mol%. On the basis of genotypic, phenotypic and chemotaxanomic findings, strain CAU 1311T could be classified as representing a novel species of a new genus of the family Rhodobacteraceae, for which the name Marimonas arenosa gen. nov., sp. nov. is proposed. The type strain of the type species is CAU 1311T (=KCTC 52189T=NBRC 111988T).
