title: Algoriphagus jejuensis sp. nov., isolated from seawater.
abstract: A gram-negative, pink-pigmented, non-motile, strictly aerobic rod, designated CNU040(T), was isolated from seawater from the coast of Jeju Island in Korea. The temperature, pH and NaCl ranges for growth were 4-30 °C, pH 5.5-10.0 and 0-5.0 % NaCl. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CNU040(T) belonged to a distinct lineage in the genus Algoriphagus and exhibited high sequence similarity with Algoriphagus terrigena DS-44(T) (98.3 %) and Algoriphagus alkaliphilus AC-74(T) (96.6 %) and lower sequence similarity (<96.0 %) with all other members of the genus Algoriphagus. DNA-DNA relatedness between strain CNU040(T) and A. terrigena KCTC 12545(T) was 44.5 %. The DNA G+C content of the isolate was 48.5 mol% and the major respiratory quinone was menaquinone-7. The major cellular fatty acids were iso-C(15 : 0) (28.6 %) and summed feature 3 (consisting of iso-C(15 : 0) 2-OH and/or C(16 : 1)ω7c; 24.0 %). The polar lipids consisted of diphosphatidylglycerol, phosphatidylethanolamine, one unknown amino lipid, one unknown aminophospholipid and three unknown polar lipids. On the basis of phenotypic, phylogenetic and genotypic data, strain CNU040(T) represents a novel species within the genus Algoriphagus, for which the name Algoriphagus jejuensis sp. nov. is proposed. The type strain is CNU040(T) ( = KCTC 22647(T)  = JCM 16112(T)).
