本文研究了134株链球菌在葡萄糖上有氧生长后，在血红素存在下的电子传递系统，通过检查电子传递的抑制以及NADH氧化的细胞位点。每个菌株被置于三个可能的组之一：细胞色素样NADH氧化酶;黄素样NADH氧化酶;或没有NADH氧化酶。大多数（88%）粪链球菌及其变种液化菌和酶原以及少数链球菌菌株。lactis及其变体diacetylactis含有细胞色素样呼吸系统。其他链球菌包括S.屎属于其他组之一，但不含细胞色素样NADH氧化酶。
The electron transport systems of 134 strains of streptococci were studied after aerobic growth on glucose in the presence of haematin, by examining the inhibition of electron transport as well as the cellular site of NADH oxidation. Each strain was placed into one of three possible groups: cytochrome-like NADH oxidase; flavin-like NADH oxidase; or no NADH oxidase. Most (88%) of the strains of Streptococcus faecalis and its variants liquefaciens and zymogenes and a few strains of S. lactis and its variant diacetylactis contained cytochrome-like respiratory systems. Other streptococci including S. faecium fell into one of the other groups but did not contain cytochrome-like NADH oxidases.
