A novel strain Vibrio aphrogenes sp. nov. strain CA-1004(T) isolated from the surface of seaweed collected on the coast of Mie Prefecture in 1994 [1] was characterized using poly phasic taxonomy including multilocus sequence analysis (MLSA) and a genome based comparison. Both phylogenetic analyses on the basis of 16S rRNA gene sequences and MLSA based on eight protein-coding genes (gapA, gyrB, ftsZ, mreB, pyrH, recA, rpoA, and topA) showed the strain could be placed in the Rumoiensis Glade in the genus Vibrio. Sequence similarities of the 16S rRNA gene and the multilocus genes against the Rumoiensis Glade members, V. rumoiensis, V. algivorus, V. casei, and V. litoralis, were low enough to propose V. aphrogenes sp. nov. strain CA-1004(T) as a separate species. The experimental DNA-DNA hybridization data also revealed that the strain CA-1004(T) was separate from four known Rumoiensis Glade species. The G+C content of the V. aphrogenes strain was determined as 42.1% based on the genome sequence. Major traits of the strain were non motile, halophilic, fermentative, alginolytic, and gas production. A total of 27 traits (motility, growth temperature range, amylase, alginase and lipase productions, and assimilation of 19 carbon compounds) distinguished the strain from the other species in the Rumoiensis Glade. The name V. aphrogenes sp. nov. is proposed for this species in the Rumoiensis Glade, with CA-1004(T) as the type strain (JCM 31643(T) = DSM 103759(T)).
