Microbial diversity supports nitrification: insights from a full-scale anoxic/oxic wastewater treatment process.

ABSTRACT: Nitrification is a crucial process for removing nitrogen in wastewater treatment systems. While previous research has primarily focused on nitrifying microorganisms, the impact of the broader diversity of non-nitrifying microbes on nitrification remains insufficiently explored. This study examined the relationship between microbial diversity and nitrification performance, taking into account the associations with nitrifiers in a full-scale anoxic/oxic activated sludge process. The microbial community was divided into a nitrifier subcommunity, comprising taxa directly responsible for nitrification, and nitrifier-associated subcommunities, comprising taxa that potentially interact with nitrifiers. Notably, the nitrifier-associated subcommunity consistently exhibited greater explanatory power
