Nitrobacter hamburgensis was shown to synthesize at least two distinct membrane‐bound b ‐type cytochromes. One of these, a minor component detected during nitrite oxidation, was also found in the obligately autotrophic species Nitrobacter winogradskyi . During heterotrophic growth of N. hamburgensis a second (major) cytochrome b was detected, which we assume functions as an alternative terminal oxidase.
