| Abstract |
A novel species belonging to the genus Grimontia is described
in this study. A Gram-negative, chemoheterotrophic, obligately
aerobic, catalase- and oxidase-positive, motile by a
single polar flagellum, and rod-shaped bacterium, designated
IMCC5001T, was isolated from surface seawater of
the Yellow Sea. Strain IMCC5001T grew optimally at 30°C
in the presence of 3.5% NaCl. Phylogenetic analysis based
on 16S rRNA gene sequences showed that the isolate was
related most closely to Grimontia hollisae with a sequence
similarity of 95.8%, and formed a robust phyletic lineage
with Grimontia hollisae. Differential physiological characteristics
between the new strain and Grimontia hollisae
KCCM 41680T and chemotaxonomic characterization including
determination of DNA G+C content, fatty acid methyl
esters, quinone composition, and polar lipid profiles justified
the assignment of strain IMCC5001T to the genus Grimontia
as a novel species. In conclusion, strain IMCC5001T represents
a new species, for which the name Grimontia marina sp.
nov. is proposed, with the type strain IMCC5001T (=KCTC
22666T =NBRC 105794T). |
