Marine bacteria require a significant amount of NaCl for optimal growth and have quite different physiological character from terrestrial counterparts. For example, marine bacteria possess a unique type ofNADH:quinone reductase, a membrane-boundenzymewhich takes part in the respiratory chain1}. This enzyme requires Na+ for its activity and with its Na+-pumping activity generates sodium-motive f...
