title: Tropicimonasarenosa sp. nov., isolated from marine sand.
abstract: A Gram-staining-negative, aerobic, non-motile, rod-shaped bacterial strain, designated CAU 1062T, was isolated from marine sand in Jeju island, Republic of Korea and its taxonomic position was investigated using a polyphasic approach. CAU 1062T grew optimally at 30 °C and pH 8 in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that CAU 1062T formed a distinct lineage within the genus Tropicimonasand was the most closely related to Tropicimonas sediminicola M97T (similarity 96.11 %). The strain had ubiquinone-10 (Q-10) as the predominant respiratory quinone and C18 : 1ω7c as the major cellular fatty acid. The polar lipid pattern of CAU 1062T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, an aminolipid, six phospholipids and five lipids. The DNA G+C content was 65.7 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, CAU 1062T represents a novel species of the genus Tropicimonas, for which the name Tropicimonas arenosa sp. nov. is proposed. The type strain is CAU 1062T (=KCTC 52178T=NBRC 111995T).
