A coryneform strain, 06-1773O(T) (=WAL 19168(T)), derived from a groin abscess sample was characterized using phenotypic and molecular taxonomic methods. Comparative analyses revealed more than 3 % divergence of the 16S rRNA gene sequence and about 10 % divergence of the partial rpoB gene sequence from the type strain of Corynebacterium glucuronolyticum. The strain could also be differentiated from C. glucuronolyticum by a set of phenotypic properties. A DNA-DNA relatedness study between strain WAL 19168(T) and C. glucuronolyticum CCUG 35055(T) showed a relatedness value of 13.3 % (13.7 % on repeat analysis). The genotypic and phenotypic data show that the strain merits classification within a novel species of Corynebacterium. We propose the name Corynebacterium pyruviciproducens sp. nov. for the novel species. The type strain is 06-1773O(T) (=WAL 19168(T) =CCUG 57046(T) =ATCC BAA-1742(T)).
一株来自腹股沟脓肿样本的棒状杆菌属菌株 06-1773O(T)(=WAL 19168(T))，通过表型和分子分类学方法进行了特征描述。比较分析显示，16S rRNA 基因序列的差异超过 3%，部分 rpoB 基因序列的差异超过 10%，与谷氨酸棒状杆菌的模式株不同。该菌株还可以通过一系列表型特性与谷氨酸棒状杆菌相区分。菌株 WAL 19168(T)与谷氨酸棒状杆菌 CCUG 35055(T)之间的 DNA-DNA 同源性研究表明，相关值为 13.3%(重复分析为 13.7%)。基因型和表型数据表明，该菌株值得在棒状杆菌属的一个新种中分类。我们建议将该新型种命名为丙酮酸发酵棒状杆菌(Corynebacterium pyruviciproducens sp. nov.)。模式菌株为 06-1773O(T)(=WAL 19168(T)=CCUG 57046(T)=ATCC BAA-1742(T))。
