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., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-93-2-195
