title: Algibacter miyuki sp. nov., a member of the family Flavobacteriaceae isolated from leachate of a brown algae reservoir.
abstract: A Gram-negative, aerobic, non-flagellated, non-gliding and rod-shaped bacterial strain, designated WS-MY6(T), was isolated from a brown algae reservoir in South Korea. Strain WS-MY6(T) grew optimally at 25 °C, at pH 7.0-8.0 and in the presence of 2 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences showed that strain WS-MY6(T) clustered with the type strains of Algibacter lectus and 'Algibacter undariae', showing 16S rRNA gene sequence similarity values of 98.1 and 98.4 %, respectively. It exhibited sequence similarities of 95.4-96.7 % to the type strains of the other Algibacter species, Pontirhabdus pectinovorans and Marinivirga aestuarii, whose reclassification into the genus Algibacter has been recently proposed. Strain WS-MY6(T) contained MK-6 as the predominant menaquinone and iso-C15:1 G, anteiso-C15:0 and iso-C17:0 3-OH as the major fatty acids. It contained phosphatidylethanolamine and two unidentified lipids as the major polar lipids. The DNA G + C content of strain WS-MY6(T) was 35.3 mol% and its DNA-DNA relatedness values with A. lectus KCTC 12103(T) and 'A. undariae' WS-MY9(T) was 21 and 13 %, respectively. The phylogenetic and genetic distinctiveness and differential phenotypic properties revealed that strain WS-MY6(T) is separate from existing Algibacter species. On the basis of the data presented, strain WS-MY6(T) is considered to represent a novel species of the genus Algibacter, for which the name Algibacter miyuki sp. nov. is proposed. The type strain is WS-MY6(T) (=KCTC 32382(T) =CECT 8300(T)).
