| Abstract: | Abstract The two key enzymes of denitrification, the nitrate and nitrate reductases, were studied in a marine organism, Pseudomonas nautica , strain 617. Both enzymes were grown under anaerobic conditions with either nitrate or nitrous oxide as electron acceptor. The effect of sodium on these enzymes was studied. Only sodium activated the membranous and purified nitrate reductase, and none of the salts affected nitrite reductase. |
