Flavobacterium oceanosedimentum Carty & Litchfield 1978(AL) had been described as a novel species in the genus Flavobacterium on the basis of phenotypic characteristics, although the organism shows a high G+C content, a property never found in the other members of the genus. In this study, we re-evaluated the taxonomic position of F. oceanosedimentum using a polyphasic approach. The 16S rRNA gene sequence of F. oceanosedimentum ATCC 31717(T) indicated that it is closely related to the genus Curtobacterium in the class Actinobacteria, showing 96.5-99.9% similarity values to Curtobacterium spp. Phylogenetic analysis based on the gene encoding the gyrase subunit B (gyrB) and DNA-DNA hybridization suggest that F. oceanosedimentum represents a separate species in the genus Curtobacterium, which is also supported by comparative analysis of cellular fatty acid profiles and a large array of phenotypic traits. We therefore propose to transfer F. oceanosedimentum to the genus Curtobacterium as Curtobacterium oceanosedimentum comb. nov.
海洋沉积物黄杆菌（Flavobacterium oceanosedimentum）Carty和Litchfield于1978年（AL）基于表型特征被描述为黄杆菌属中的一个新物种，尽管该菌显示出高G+C含量，这是该属其他成员从未发现的特性。在本研究中，我们采用多相分类方法重新评估了海洋沉积物黄杆菌的分类地位。海洋沉积物黄杆菌ATCC 31717(T)的16S rRNA基因序列表明，它与放线菌纲中的短小杆菌属密切相关，与短小杆菌属各菌株的相似性值为96.5 - 99.9%。基于编码gyrase亚基B（gyrB）的基因和DNA-DNA杂交的系统发育分析表明，海洋沉积物黄杆菌代表短小杆菌属中的一个独立物种，细胞脂肪酸谱和大量表型特征的比较分析也支持这一点。因此，我们建议将海洋沉积物黄杆菌转移到短小杆菌属，命名为海洋沉积物短小杆菌（Curtobacterium oceanosedimentum）新组合。
