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 anteiso-C15:0. 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 426T followed by Arenibacter certesii CCUG 48006T (98.6%) and other members of the genus Arenibacter (< 97%). The genome size of strain JC631T is 4.16 Mb with a GC content of 40.8 mol%. Strain JC631T has ANI scores of 78.3% and 78.1%; dDDH values of 22.2% and 21.8%, respectively, with the type strains of A. latericius and A. certesii. The genomic distinction is well supported by chemotaxonomic characteristics and differential physiological properties. This supports strain JC631T to be described as a new species of the genus Arenibacter, named as Arenibacter lacus sp. nov. The type strain is JC631T (= KCTC 72002T = NBRC 114071T).

革兰杆菌属。11 月，与印度奇利卡泻湖隔离

从印度 Chilika 泻湖的沉积物生态系统中分离出一种有光泽的深黄色、革兰氏染色阴性、杆状、非运动性细菌，命名为 JC631T 菌株。菌株 JC631T 可耐受高达 10 的 pH 值和高达 3% (w/v) 的 NaCl。MK6 是唯一的呼吸醌。主要 (> 10%) 细胞脂肪酸是反异-C11:0、反异-C13:0 和反异-C15:0。主要的极性脂质是磷脂酰乙醇胺、磷脂酰胆碱、一些未鉴定的磷脂和一些未鉴定的氨基脂。16S rRNA基因测序显示，菌株JC631T与山梨杆菌KMM 426T的序列同一性最高（98.7%），其次是假山梨杆菌CCUG 48006T（98.6%）和其他砂杆菌属（<97%）。菌株 JC631T 的基因组大小为 4.16 Mb，GC 含量为 40.8 mol%。菌株 JC631T 的 ANI 得分分别为 78.3% 和 78.1%；dDDH 值分别为 22.2% 和 21.8%，与 A. latericius 和 A. certesii 的模式菌株。化学分类学特征和不同的生理特性很好地支持了基因组的区别。这支持菌株JC631T 被描述为Arenibacter 属的一个新物种，命名为Arenibacter lacus sp。十一月 类型菌株是 JC631T (= KCTC 72002T = NBRC 114071T)。
