Strain 96-237T, a Gram-reaction-negative, curved- to spiral-shaped motile bacterium, isolated from coastal marine water, was found to be related to species of the genus Grimontia by 16S rRNA gene sequence comparison, sharing 98.3% similarity to Grimontia marina CECT 8713Tand 98.8% to 'Grimontiaindica' AK16. Phenotypic analysis revealed that strain 96-237T is slightly halophilic, mesophilic and facultatively anaerobic, fermenting D-glucose, D-ribose, Dmannose, D-mannitol, maltose and sucrose. It was positive for oxidase and indole production and negative for arginine dihydrolase and lysine and ornithine decarboxylases. Its major fatty acids were C16 : 1!7c/C16 : 1!6c (SF3), C18 : 1!7c and C16 : 0. Its DNA G+C content was 48.4 mol%. The strain was different at the species level from all other species of the genus Grimontia, with average nucleotide identity indices of 79.6% to Grimontia. hollisae CECT 8713T, 87.8% to G. marina CECT 5069T and 89.1% to 'G. indica' AK16 genomes. Thus, the strain represents a novel species for which we propose the name Grimontia celer and 96-237T (=CECT 9029T =KCTC 42960T =LMG 29238T) as the type strain.
