• Cytochrome systems in cells of a denitrifying bacterium, Pseudomonas stutzeri (VAN NIEL strain), grown under different atmospheric conditions were compared with reference to the effects of nitrate and nitrite on cytochrome synthesis. When a culture was sufficiently aerated (aerobic conditions), synthesis of all cytochrome components was repressed, regardless of the presence or absence of nitrate and nitrite. When aerated moderately (semi-aerobic conditions), both soluble and particulate cytochromes c-552 and cytochrome b-558 contents markedly increased even in the absence of nitrate and nitrite. Under anaerobic or semi-aerobic conditions, nitrite induced cytochrome a2-c synthesis. This inductive effect of nitrite was counteracted by nitrate. Nitrate also repressed particulate cytochrome c-552 synthesis to some extent but nitrite did not.
