The phylogenetic relationships among members of the family Comamonadaceae and several unclassified strains were studied by direct sequencing of their PCR-amplified 16S rRNA genes. Based on the 16S rRNA gene sequence analysis, members of the family formed a coherent group. The closest relatives are species of the Rubrivivax sub-group: Leptothrix discophora, Ideonella dechloratans and Rubrivivax gelatinosus. The genus Hydrogenophaga formed two subclusters, as did the species of Acidovorax, whereas the five species of the genus [Aquaspirillum] were polyphyletic. Comamonas acidovorans was phylogenetically distant from the type species of Comamonas, Comamonas terrigena. On the basis of this work and previous studies, Comamonas acidovorans is removed from the genus Comamonas and renamed as Delftia acidovorans gen. nov., comb. nov. Descriptions of the new genus Delftia and of the type species Delftia acidovorans, for which the type strain is ATCC 15668T, are presented.
通过对科马氏菌科成员及几种未分类菌株的PCR扩增16S rRNA基因进行直接测序，研究了它们之间的系统发育关系。基于16S rRNA基因序列分析，该科成员形成了一个连贯的类群。其最亲近的亲缘种是红环菌亚群的物种：盘状纤发菌、脱氯食酸菌和胶状红环菌。嗜氢菌属形成了两个亚簇，嗜酸菌属的物种也是如此，而[水生螺菌属]的五个物种是多系的。食酸丛毛单胞菌在系统发育上与丛毛单胞菌属的模式种土生丛毛单胞菌相距较远。基于这项工作和先前的研究，食酸丛毛单胞菌被从丛毛单胞菌属中移除，并重新命名为食酸代尔夫特菌，新属名，新组合名。本文给出了新属代尔夫特菌及模式种食酸代尔夫特菌的描述，其模式菌株为ATCC 15668T。
