Electron transport chain in aerobically cultivated Zymomonas mobilis

1996

Respiratory chain composition and energy coupling in cytoplasmic membrane of Zymomonas mobilis was shown to depend on culture aeration. Aerobically grown cells contained mainly the non-energy-generating NADH dehydrogenase with kM for NADH 58 mM. In anaerobically cultivated bacteria, the energy-coupling NADH dehydrogenase complex with km for NADH 7 mM predominated. In aerobically cultivated Z. mobilis, CoQ content and absorption peaks of cytochromes at 554–556 nm and 525–528 nm were significantly increased. Energy-coupling site I, linked to the NADH:CoQ oxidoreductase complex, could be eliminated under sulfate-deficient cultivation conditions. For anaerobically grown cells this resulted in l…
