Ammonia or ammonium ion as substrate for oxidation by Nitrosomonas europaea cells and extracts.

Abstract

The effect of pH on the K(m) values for ammonia was studied in its oxidation by Nitrosomonas cells and cell-free extracts. The K(m) values decreased markedly with increasing pH, suggesting (NH(3)) rather than (NH(4) (+)) as the actual substrate for oxidation.
