Growth occurred at 4–36 °C (optimum 20–25 °C), pH 6.0–8.5 (optimum 7.5–8.0) and in the presence of 1–8 % (w/v) NaCl (optimum 2–3 %). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain P308H10T lies within the clade of members of the genus Arenibacter and is closely related to Arenibacter hampyeongensis HP12T (98.0 %), Arenibacter echinorum KMM 6032T (98.4 %), Arenibacter palladensis LMG 21972T (97.9 %), Arenibacter troitsensis KMM 3674T (97.9 %) and ‘ Arenibacter algicola’ TG409 (98.1 %). The average nucleotide identity and digital DNA–DNA hybridization values between strain P308H10T and the five reference strains were 85.9–80.6 % and 30.2–23.6 %, respectively. The major fatty acids (>10 %) of strain P308H10T were summed feature 3, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0. The major polar lipids comprised phosphatidylethanolamine, five unidentified aminolipids and four unidentified lipids. The only respiratory quinone was menaquinone-6. The genomic DNA G+C content was 38.2 mol%. On the basis of the phenotypic, phylogenetic and chemotaxonomic data presented, strain P308H10T represents a novel species of the genus Arenibacter , for which the name Arenibacter catalasegens sp. nov. is proposed. The type strain is P308H10T (=GDMCC 1.1230T=KCTC 52983T). An emended description of the genus Arenibacter is also proposed.", }
