A denitrifier micro-organism was isolated from an upflow denitrifying filter inoculated with an activated sludge. The cells were Gram-negative, catalase- and oxidase-positive curved rods and very motile. They were aerobic as well as anoxic heterotrophs that had an atypical respiratory type of metabolism in which oxygen and nitrogen oxides were used simultaneously as terminal electron acceptors. The G&C content was 65 mol%. Our isolate was phenotypically similar to Comamonas testosteroni, according to classical systematic classification systems. However, a phylogenetic analysis based on the 165 rRNA sequence showed that the aerobic denitrifier could not be assigned to any currently recognized genus. For these reasons a new genus and species, Microvirgula aerodenitrificans gen. nov., sp. nov., is proposed, for which SGLY2T is the type strain.
从接种活性污泥的上流式反硝化滤池中分离出一种反硝化微生物。细胞为革兰氏阴性、过氧化氢酶和氧化酶阳性的弯曲杆菌,运动性很强。它们是好氧以及缺氧异养菌,具有非典型的呼吸代谢类型,其中氧气和氮氧化物同时用作末端电子受体。G+C含量为65摩尔%。根据经典的系统分类系统,我们分离出的菌株在表型上与睾丸丛毛单胞菌相似。然而,基于16S rRNA序列的系统发育分析表明,这种好氧反硝化菌不能归属于任何目前已被认可的属。基于这些原因,提出了一个新的属和种,即嗜氧反硝化微小杆菌属(Microvirgula aerodenitrificans),新属,新种,其中SGLY2T为模式菌株。
