In this paper, we report on the identification and species characterization of a novel Gram-staining-negative bacterium, strain S61(T), isolated from the deep-sea sediment of the Okinawa Trough. Growth of strain S61(T) occurred at 4-37(o)C (optimum, 25(o)C), pH 6.0-10.0 (optimum, pH 7.0) and with 0-8% (w/v) NaCl (optimum, 2 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain S61(T) belonged to the genus Algoriphagus. The closest phylogenetic neighbours of strain S61(T) were Algoriphagus lutimaris S1-3(T) (98.1 %), Algoriphagus halophilus JC2051(T) (98.1 %), Algoriphagus chungangensis CAU 1002(T) (98.0 %) andAlgoriphagus aestuarii MDM-1(T) (97.4 %). The sequence similarities between strain S61(T) and other close members of the genus were below 97 %. The values of DNA-DNA relatedness between strain S61(T) and its closest relatives in the genus Algoriphagus were well below 70 %. The genomic DNA G+C content of strain S61(T) was 40.2 mol%. The major menaquinone was MK-7. The polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified phospholipids and one unidentified lipid. The major fatty acids were iso-C-15 : 0 and summed feature 3 (C-16 : 1 omega 6c and/ or C-16 : 1 omega 7c). Phylogenetic, physiological, biochemical, and morphological analyses suggested that this strain represents a novel species of the genus Algoriphagus, for which the name Algoriphagus iocasae sp. nov. is proposed with the type strain S61(T) (=KCTC 52359(T)=CCTCC AB 2015446(T)).
