A Gram-stain-negative, non-flagellated, rod-shaped bacterial strain able to move by gliding, designated WS-MY22T, was isolated from sediment around a brown algae reservoir located on Wando in South Korea. It grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Phylogenetic trees based on 16S rRNA gene sequences showed that strain WS-MY22T clustered coherently with the type strains of Algibacter lectus and Algibacter undariae. It exhibited sequence similarity of 99.4 and 98.9 % to the type strains of A. lectus and A. undariae, respectively, and of 95.1–96.6 % to those of the other species of the genus Algibacter. Strain WS-MY22T contained MK-6 as the predominant menaquinone and iso-C15 : 1 G and iso-C17 : 0 3-OH as the major fatty acids. The major polar lipids of strain WS-MY22T were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content of strain WS-MY22T was 35.8 mol% and its DNA–DNA relatedness with A. lectus KCTC 12103T and A. undariae WS-MY9T was 31 and 19 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WS-MY22T is separate from other species of the genus Algibacter. On the basis of the data presented, strain WS-MY22T is considered to represent a novel species of the genus Algibacter, for which the name Algibacterwandonensis sp. nov. is proposed. The type strain is WS-MY22T ( = KCTC 32381T = CECT 8301T).
