Abstract A shiny dark yellow pigmented, Gram-stain-negative, rod-shaped, non-motile bacterium, designated as strain ­JC631T, was isolated from the sediment ecosystem of Chilika lagoon, India. Strain ­JC631T tolerates up to pH 10 and NaCl up to 3% (w/v). MK6 is the only respiratory quinone. Predominant (> 10%) cellular fatty acids are anteiso-C11:0, anteiso-C13:0, and anteisoC15:0. Major polar lipids are phosphatidylethanolamine, phosphatidylcholine, a few unidentified phospholipids, and a few unidentified aminolipids. 16S rRNA gene sequencing showed that strain ­JC631T shared the highest sequence identity (98.7%) with Arenibacter latericius KMM 4­ 26T followed by Arenibacter certesii CCUG 4­ 8006T (98.6%) and other members of the genus Arenibacter (
