Description A novel Gram- stain- negative, curved rod- shaped, 0.5?0.7 ?m wide and 3.0?10.0 ?m long, non- motile bacterium, designated strain AK53T, was isolated from a 5 m depth water sample collected from the Bay of Bengal, Visakhapatnam, India. Colonies on marine agar were circular, small, dark orange, shiny, smooth, translucent, flat, with an entire margin. The major fatty acids included iso-C15:0, iso-C15: 0 3OH, anteiso- C15:0, iso-C15: 1 G, iso- C17: 0 3OH and summed feature 3 (C16:1 ?7c and/or C16:1 ?6c and/or iso-C15:0- 2OH). Polar lipids included phosphatidylethanolamine and five unidentified lipids. The DNA G+C content of the strain AK53T was found to be 40.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain AK53T was closely related to Arenibacter latericius KMM 426T and Arenibacter certesii KMM3941T (pair- wise sequence similarity of 99.17 and 98.89 %, respectively), forming a distinct branch within the genus Arenibacter and clustering with A. latericius. Strain AK53T shared average nucleotide identity (ANIb, based on BLAST) of 78.07 and 77.44 % with A. latericius JCM 13508T and A. certesii JCM 13507T, respectively. Based on the observed phenotypic, chemotaxonomic characteristics and phylogenetic analysis, strain AK53T is described in this study as representing a novel species in the genus Arenibacter, for which the name Arenibacter amylolyticus sp. nov. is proposed. The type strain of Arenibacter amylolyticus is AK53T (=MTCC 12004T= JCM 19206T=KCTC 62553T).
