A yellow-pigmented, Gram-negative, aerobic bacterial strain comprising rod-shaped cells devoid of flagellar and gliding motility, designated strain JC2129(T), was isolated from tidal flat sediment of Dongmak on Ganghwa Island, South Korea. Results from a 16S rRNA gene sequence analysis indicated that the isolate belonged to the family Flavobacteriaceae; the highest level of nucleotide sequence similarity (91.9%) occurred with Polaribacter dokdonensis DSW-5(T). The predominant cellular fatty acids were iso-C(15:0) (19.8%), iso-C(15:1) G (14.0%), iso-C(17:0) 3-OH (13.7%) and iso-C(13:0) (6.4%). Flexirubin-type pigments were absent. The major isoprenoid quinone was MK-6. The DNA G+C content was 43-45 mol%. Data from a polyphasic taxonomy study suggested that the isolate represents a novel genus and species in the family Flavobacteriaceae, for which the name Actibacter sediminis gen. nov., sp. nov. is proposed. The type strain of Actibacter sediminis is JC2129(T) (=KCTC 12704(T) =JCM 14002(T)).
从韩国江华岛东马克的潮滩沉积物中分离出一株黄色色素、革兰氏阴性、需氧的细菌菌株，该菌株由无鞭毛且无滑行运动的杆状细胞组成，命名为菌株JC2129(T)。16S rRNA基因序列分析结果表明，该分离株属于黄杆菌科；与多岛海极地杆菌DSW-5(T)的核苷酸序列相似性最高（91.9%）。主要的细胞脂肪酸为异-C(15:0)（占19.8%）、异-C(15:1) G（占14.0%）、异-C(17:0) 3-OH（占13.7%）和异-C(13:0)（占6.4%）。不存在柔韧红素型色素。主要的类异戊二烯醌为MK-6。DNA的G+C含量为43 - 45 mol%。多相分类研究的数据表明，该分离株代表黄杆菌科中的一个新属和新种，为此提出新属名Actibacter（沉积物杆菌属），新种名Actibacter sediminis（沉积物沉积物杆菌）。沉积物沉积物杆菌的模式菌株为JC2129(T)（=KCTC 12704(T) =JCM 14002(T)）。
