Genus species - Mariniflexile aquimaris - Type Strain HWR-17t - Mariniflexil [Ma.ri.ni.fle′xi.le. L. adj. marinus marine; L. part. adj. flexilis -e pliant, pliable, flexible; N.L. neut. n. Mariniflexile a flexible marine (bacterium)]. - Mariniflexile aquimaris (a.qui.ma′ris. L. n. aqua water; L. gen. n. maris of the sea; N.L. gen. n. aquimaris of the water of the sea).

Description and significance

The genus Mariniflexile, a member of the family Flavobacteriaceae, phylum Bacteroidetes, was proposed by Nedashkovskaya et al. (2006) with Mariniflexile gromovii, isolated from a sea urchin, as the sole recognized species. Mariniflexile aquimaris is a novel species to the genus Mariniflexile that was discovered in Yellow Sea off Hwang-do, an island in Korea (Jung, Kim, Oh & Yoon, 2012). This species exhibited 97.1-97.2% 16S rRNA gene sequencing with Mariniflexile gronovii KCTC 12570T and Mariniflexile fucanivorans DSM 18792T (Jung, Kim, Oh & Yoon, 2012). There were, however, distinct phenotypic differences that the discovery of Mariniflexile aquimaris that an amendment to the description of the genus was proposed (Jung, Kim, Oh & Yoon, 2012). The new description is as follows: Motile by gliding or non-gliding. Optimal growth temperature is 25–30 °C. Oxidase activity is negative. The major polar lipids are phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid (Jung, Kim, Oh & Yoon, 2012).
