title: Gaetbulibacter jejuensis sp. nov., isolated from seawater.
abstract: A novel marine bacterium, designated strain CNURIC014(T) was isolated from coastal seawater of Jeju Island in Korea. Strain CNURIC014(T) formed yellow colonies on marine agar 2216 and the cells were Gram-negative, non-motile, strictly aerobic, rod-shaped. The temperature, pH and NaCl ranges for growth were 15-37 degrees C, pH 6.0-9.0 and 1.0-7.0% NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CNURIC014(T) was most closely related to Gaetbulibacter marinus and Gaetbulibacter saemankumensis, with a sequence similarity of 95.1% and 94.6%, respectively. The DNA G+C content of the strain was 33.1 mol% and the major respiratory quinone was menaquinone-6. The major cellular fatty acids were iso-C(15:1) (22.8%), iso-C(15:0) (18.8%), summed feature 3 (iso-C(15:0) 2-OH/C(16:1) omega 7c, 12.9%) and iso-C(17:0) 3-OH (11.5%). On the basis of phenotypic, phylogenetic, and genotypic data, strain CNURIC014(T) represents a novel species within the genus Geatbulibacter, for which the name Gaetbulibacter jejuensis sp. nov. is proposed. The type strain is CNURIC014(T)(=KCTC 22615(T) =JCM 15976(T)).
