A yellow-pigmented, Gram-negative, aerobic bacterial strain comprising rod-shaped cells devoid of flagellar and gliding motility, designated strain A31(T), was isolated from a veined rapa whelk (Rapana venosa) collected from the South Sea, Republic of Korea. Results from 16S rRNA gene sequence analysis indicated that the isolate belonged to the family Flavobacteriaceae; the highest level of nucleotide sequence similarity (92.6 %) was observed with Tenacibaculum aestuarii KCTC 12569(T). The predominant cellular fatty acids were iso-C(15 : 1) G (24.2 %), iso-C(15 : 0) (20.1 %) and iso-C(17 : 0) 3-OH (11.2 %). Flexirubin-type pigments were absent. The major isoprenoid quinone was MK-6. The DNA G+C content was 31.7 mol%. Data from a polyphasic taxonomic study suggested that the isolate represents a novel species in a new genus of the family Flavobacteriaceae, for which the name Maritimimonas rapanae gen. nov., sp. nov. is proposed. The type strain of Maritimimonas rapanae is A31(T) (=KCTC 22186(T) =JCM 15075(T)).
从韩国南海采集的脉红螺（Rapana venosa）中分离出一株黄色色素、革兰氏阴性、需氧的细菌菌株，其细胞呈杆状，无鞭毛且不具备滑行运动能力，命名为菌株A31(T)。16S rRNA基因序列分析结果表明，该分离株属于黄杆菌科；与河口韧杆菌（Tenacibaculum aestuarii）KCTC 12569(T)的核苷酸序列相似性最高（92.6%）。主要的细胞脂肪酸为异-C(15 : 1) G（24.2%）、异-C(15 : 0)（20.1%）和异-C(17 : 0) 3-OH（11.2%）。不存在flexirubin型色素。主要的类异戊二烯醌为MK-6。DNA G+C含量为31.7 mol%。多相分类研究数据表明，该分离株代表黄杆菌科一个新属中的一个新物种，为此提出新属名海生单胞菌属（Maritimimonas），新种名脉红螺海生单胞菌（Maritimimonas rapanae）。脉红螺海生单胞菌的模式菌株为A31(T)（=KCTC 22186(T) =JCM 15075(T)）。
