Gillisia marina sp. nov., from seashore sand, and emended description of the genus Gillisia.

A Gram-staining-negative, strictly aerobic, rod-shaped bacterium, designated CBA3202(T), was isolated from seashore sand on Jeju Island, Republic of Korea. Based on the 16S rRNA gene sequence analysis, strain CBA3202(T) 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 acids were C16 : 0, iso-C15 : 1 G, iso-C16 : 0 and summed feature 3 (comprising C16 : 1ω6c and/or C16 : 1ω7c), 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 CBA3202(T) represents a novel species of the genus Gillisia, for which the name Gillisia marina sp. nov. is proposed. The type strain is CBA3202(T) ( = KACC 16693(T) = KCTC 32030(T) = JCM 18402(T)). An emended description of the genus Gillisia is also provided.
