When K. pneumoniae cells were grown anaerobically with nitrate as the final electron acceptor, there was a rapid reduction of nitrate to nitrite. The latter was further reduced to hydroxylamine and finally to ammonia. Nitrate, nitrite and nitric oxide, but not nitrous oxide, could accept electrons from the respiratory chain. During growth of the organism it was possible to trap nitric oxide with alkaline permanganate. The trapped gas represented only a small portion of the reduced electron acceptor. It would appear that a major portion of nitric oxide produced from nitrite reduction must be converted to an unknown nitrogenous intermediate with an oxidation state of +1 before its reduction to hydroxylamine. The possible nature of this elusive intermediate should be discussed.
