anammox bacteria sequencing
Particularly, two anammox genera Ca. Brocadia (relative abundance of 17.05%) and Ca. Kuenenia (relative abundance of 0.22%) were enriched under this mode. This mode not only reduced the operational complexity and cost of anammox systems but also demonstrated adaptability to practical wastewater conditions. By balancing substrate availability and promoting species cooperation, the PN/A-like mode enables low-cost, high-efficiency nitrogen removal in practical applications, paving the way for broader implementation of anammox-based technologies in wastewater treatment.
