摘要: Photoinhibition of ammonia oxidation occurs widely in aquatic environments and could suppress the nitrification rate, lead to the composition variation of inorganic nitrogen and influence the stability of aquatic ecosystems. Both ammonia-oxidizing bacteria (AOB) and archaea are sensitive to light. The extent of photoinhibition and the time required for recovery depend on light wavelength, intensity, photon quantity and strains. Strong evidence indicates that photoinhibition in AOB by visible light is mainly caused by irreversible damage to ammonia monooxygenase (AMO) and the degradation of AMO is beneficial to AOB recovery. This review discusses photoinhibition in metabolic pathways used by ammonia oxidizers.
