A yellow-coloured, rod-shaped, Gram-reaction-negative, aerobic bacterial strain, designated JC2132(T), was isolated from a tidal flat sediment sample from Ganghwa Island, Korea. The isolate required sea salts for growth. Cells produced non-diffusible carotenoid pigments, but flexirubin-type pigments were absent. Gliding motility was observed. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain JC2132(T) represented a distinct phyletic line that reflected a novel generic status within the family Flavobacteriaceae with relatively low sequence similarities (<95 %) to members of other genera with validly published names. The predominant isoprenoid quinone (MK-6) and DNA G+C content (35 mol%) were consistent with assignment of the isolate to the family Flavobacteriaceae, but overall phenotypic traits demonstrated that strain JC2132(T) was not closely affiliated with any previously described genera. Based on taxonomic data obtained using a polyphasic approach, it is proposed that strain JC2132(T) represents a novel species in a new genus belonging to the family Flavobacteriaceae, for which the name Snuella lapsa gen. nov., sp. nov. is proposed; the type strain of the type species is JC2132(T) ( = KACC 14152(T) = JCM 17111(T)).
一株黄色、杆状、革兰氏反应阴性、需盐好氧的细菌菌株,命名为 JC2132(T),从韩国 Ganghwa 岛的潮滩沉积物样本中分离得到。该菌株的生长需要海盐水。细胞产生非扩散性类胡萝卜素色素,但不存在柔韧菌素型色素。观察到滑动运动。基于 16S rRNA 基因序列的系统发育分析表明,菌株 JC2132(T)代表了一个独特的进化谱系,反映了在黄杆菌科内具有新颖的属级地位,与具有有效发表名称的其他属成员的序列相似性相对较低(<95%)。主要的异戊二烯醌(MK-6)和 DNA G+C 含量(35 mol%)与将该分离物分配给黄杆菌科一致,但总体表型特征表明,菌株 JC2132(T)与任何先前描述的属都没有密切的联系。基于多相方法获得的分类学数据,建议菌株 JC2132(T)代表一个新属的新物种,属于黄杆菌科,建议使用新属名 Snuella lapsa gen. nov.,sp. nov.。该模式种的模式菌株为 JC2132(T)(=KACC 14152(T)=JCM 17111(T))。
