Nitrosomonas europaea and Thiobacillus novellus were compared with each other on the basis of the biochemical properties of their inorganic compound-oxidizing systems. Cytochromes c of the two organisms differ considerably from each other; N. europaea cytochrome c-552 belongs to the "bacterial-type" cytochrome c, while T. nouellus cytochrome c-550 resembles eucaryolic cytochrome c. The specificity of cytochrome oxidase for cytochrome c as the electron donor is different between the two organisms; T novellus oxidase reacts rapidly with cytochromes c of the organisms which seem to be higher than the organisms whose cytochromes c react rapidly with N. europaea oxidase. On the basis of these facts, N. europaea seems to be older organism than T. novellus in terms of evolution.
根据欧洲亚硝化单胞菌和新型硫杆菌无机化合物氧化系统的生化特性对二者进行了比较。两种生物的细胞色素c彼此差异很大；欧洲亚硝化单胞菌的细胞色素c-552属于“细菌型”细胞色素c，而新型硫杆菌的细胞色素c-550类似于真核细胞色素c。两种生物中细胞色素氧化酶对作为电子供体的细胞色素c的特异性不同；新型硫杆菌氧化酶与细胞色素c反应迅速的生物的细胞色素c反应迅速，而这些生物似乎比细胞色素c与欧洲亚硝化单胞菌氧化酶反应迅速的生物更高等。基于这些事实，就进化而言，欧洲亚硝化单胞菌似乎是比新型硫杆菌更古老的生物。
