Pseudomonas facilis and Pseudomonas delafieldii are inappropriately assigned to the genus Pseudomonas. They belong to the acidovorans rRNA complex in rRNA superfamily III (i.e., the beta subclass of the Proteobacteria). The taxonomic relationships of both of these species, two groups of clinical isolates (E. Falsen [EF] group 13 and EF group 16), and several unidentified or presently misnamed strains were examined by using DNA:rRNA hybridization, numerical analyses of biochemical and auxanographic features and of fatty acid patterns, polyacrylamide gel electrophoresis of cellular proteins, and DNA:DNA hybridization. These organisms form a separate group within the acidovorans rRNA complex, and we propose to transfer them to a new genus, Acidovorax. We describe the following three species in this genus: the type species, Acidovorax facilis (formerly Pseudomonas facilis), with type strain LMG 2193 (= CCUG 2113 = ATCC 11228); Acidovorax delafieldii (for the former Pseudomonas delafieldii and most of the EF group 13 strains), with type strain LMG 5943 (= CCUG 1779 = ATCC 17505); and Acidovorax temperans (for several former Pseudomonas and Alcaligenes strains and most of the EF group 16 strains), with type strain CCUG 11779 (= LMG 7169).
易变假单胞菌和德拉菲尔德假单胞菌被不恰当地归为假单胞菌属。它们属于rRNA超家族III中的嗜酸菌rRNA复合体（即变形菌纲的β亚类）。通过DNA:rRNA杂交、生化和营养特征及脂肪酸模式的数值分析、细胞蛋白的聚丙烯酰胺凝胶电泳以及DNA:DNA杂交，研究了这两个菌种、两组临床分离株（E. Falsen [EF] 13组和EF 16组）以及几株未鉴定或目前命名错误的菌株的分类关系。这些微生物在嗜酸菌rRNA复合体中形成一个独立的类群，我们建议将它们转移到一个新属——嗜酸菌属。我们在此属中描述以下三个种：模式种，易变嗜酸菌（以前的易变假单胞菌），模式菌株为LMG 2193 (= CCUG 2113 = ATCC 11228)；德拉菲尔德嗜酸菌（针对以前的德拉菲尔德假单胞菌和大多数EF 13组菌株），模式菌株为LMG 5943 (= CCUG 1779 = ATCC 17505)；以及温和嗜酸菌（针对几株以前的假单胞菌和产碱菌菌株以及大多数EF 16组菌株），模式菌株为CCUG 11779 (= LMG 7169)。
