This lecture covers the processes of nitrification and anammox, which involve the oxidation of ammonium under different conditions. Nitrification occurs in two steps, involving ammonia and nitrite oxidation, with oxygen as the electron acceptor. Anammox, on the other hand, occurs under anoxic conditions. The lecture explains the mechanisms of ammonia oxidation to hydroxylamine and further to nitrite, as well as the conversion of nitrite to nitrate. It also delves into the biochemistry of anammox, detailing the role of enzymes like Nitrite Reductase and Hydrazine Synthase. Additionally, it discusses the organisms involved in these processes, such as Nitrobacter and Nitrosomonas. Overall, the lecture emphasizes the significance of nitrification and anammox in water biogeochemistry.
