ABSTRACT: A Gram-staining-negative, strictly aerobic, rod-shaped bacterium, designated CBA3202T, was isolated from seashore sand on Jeju Island, Republic of Korea. Based on the 16S rRNA gene sequence analysis, strain CBA3202T was allocated to the genus Gillisia (family Flavobacteriaceae) and was most closely related to the type strain of Gillisia mitskevichiae (99.0 % 16S rRNA gene sequence similarity). Optimal growth occurred at 25°C and with 3 % NaCl. The only isoprenoid quinone was menaquinone-6 (MK-6), the predominant fatty acid were C16:0, iso-C15:1 G, iso-C16:0, and summed feature 3 (comprising C16:1 ω6c and/or C16:1 ω7c), and the DNA G+C content was 34.9 mol%. The polar lipids were phosphatidylethanolamine, two unidentified aminolipids, and several unidentified polar lipids. Based on phylogenetic inference and phenotypic data, we conclude that strain CBA3202T represents a new species in the genus Gillisia, for which the name Gillisia marina sp. nov. is proposed. The type strain is CBA3202T (=KACC 16693T =KCTC 32030T =JCM 18402T). An emended description of the genus Gillisia is also provided.
