[Electron transport systems of Photobacterium fischeri].
The composition of cytochromes was studied in Photobacterium fischeri 6 at different growth phases and under various conditions of cultivation. The electron transport chains of the bacterium are characterized by the presence of cytochromes b and c types. The terminal oxidases are cytochromes o, a2+a1 and P-450. The hemoprotein P-450 functions as a mixed function oxidase. The qualitative composition of cytochromes does not depend on the growth phase of the bacterium but does on the conditions of cultivation. The bacterium synthesizes cytochromes a2+a1 in the conditions of oxygen deficiency. The synthesis of cytochrome o depends on the composition of the medium.
