A Gram-negative, short rod-shaped, nitrogen-fixing bacterium (CC-21(T)) was isolated from a soil sample collected from the regional agricultural research station in Kaohsiung County (Taiwan). Using 16S rRNA gene sequence analysis, it could be clearly demonstrated that this isolate was novel: it showed <97 % similarity to species of the genera Acidovorax, Alicycliphilus, Giesbergeria, Simplicispira and Diaphorobacter. The organism used several organic acids, but only a few sugars as substrates. The fatty acid profile differed from those reported for members of the genera Acidovorax, Alicycliphilus, Giesbergeria, Simplicispira and Diaphorobacter. On the basis of 16S rRNA gene sequence analysis in combination with physiological data, strain CC-21(T) represents a novel species in a new genus, for which the name Pseudacidovorax intermedius gen. nov., sp. nov. is proposed; the type strain is CC-21(T) (=CCUG 54492(T)=CIP 109510(T)).
从台湾高雄县区域农业研究站采集的土壤样本中分离出一株革兰氏阴性、短杆状的固氮细菌（CC-21(T)）。通过16S rRNA基因序列分析，可以清楚地证明该分离株是新的：它与嗜酸菌属、嗜环菌属、吉斯贝格菌属、简单螺旋菌属和双杆菌属的物种相似度小于97%。该菌株利用多种有机酸，但仅利用少数几种糖作为底物。其脂肪酸谱与嗜酸菌属、嗜环菌属、吉斯贝格菌属、简单螺旋菌属和双杆菌属成员报道的不同。基于16S rRNA基因序列分析并结合生理数据，菌株CC-21(T)代表一个新属中的一个新物种，为此提出新属名中间假嗜酸菌属（Pseudacidovorax），新种名中间假嗜酸菌（Pseudacidovorax intermedius）；模式菌株为CC-21(T)（=CCUG 54492(T)=CIP 109510(T)）。
