Feammox, an innovative and energy-efficient biological ammonium removal technology, has attracted significant attention in recent years. Defined as the anaerobic oxidation coupled with Fe(III) reduction, Feammox involves Fe(III)-reducing microbes that oxidize to nitrite using ferric ions. Identified diverse ecosystems, such freshwater, marine, natural wetlands, wastewater plays a vital role global nitrogen cycle. Numerous studies have investigated its performance, influencing factors, reaction mechanisms, engineering applications. However, our understanding of functional microorganisms key genes involved remains limited controversial. Clearly identifying characterizing responsible for process are essential practical application treatment. Therefore, this review critically analyzes summarizes advances research, focus on microorganisms, genes, regulation strategies. Initially, discusses from perspective microbial cooperation. It then delves into enzymatic genetic mechanisms well critical factors affecting activity. Finally, strategies enhance efficiency systematically outlined. This comprehensive analysis current research provides clearer more complete deepens knowledge establishes solid foundation application.
