| Abstract |
A bacterial strain, JH03(T), was isolated from gravel adjacent to Geommeolle beach on Udo Island, South Korea. The cells were Gram-stain-negative, aerobic, non-motile and rod shaped. The ranges of temperature, pH and NaCl concentration for growth of the bacterium were 10-45 °C, pH 6.0-9.5 and 0.5-5.0 % (w/v), respectively. The major fatty acids of the bacterium were iso-C(15:0) (15.4 %), iso-C(15:1) G (14.1 %), iso-C(16:0) 3-OH (14.1 %), iso-C(17:0) 3-OH (11.5 %) and anteiso-C(15:0) (11.3 %). The major isoprenoid quinone was MK-6. The polar lipids included phosphatidylethanolamine, two unidentified amino lipids and three unidentified lipids. The DNA G+C content was 34.2 mol%. The phylogenetic analysis of the 16S rRNA gene sequences showed that strain JH03(T) was most closely related to Jejuia pallidilutea EM39(T) (96.5 % sequence similarity). Based on the polyphasic analysis, strain JH03(T) is a novel species of the genus Jejuia, for which the name Jejuia marina sp. nov. is proposed. The type strain is JH03(T) (= KCTC 42342(T) = JCM 30601(T)).
