Optimal Phosphate Concentration for Growth and Normal Functioning of Marine Anammox Bacteria, Candidatus Scalindua sp.

ABSTRACT: The anammox process using marine anammox bacteria is a promising nitrogen removal process for recirculating aquaculture system wastewater. Marine anammox bacteria are typically found in oxygen-deficient zones and coastal areas under low phosphate concentrations. The optimal phosphate concentration for marine anammox bacteria remains unknown because most laboratory studies on these bacteria have been conducted under high phosphate concentrations. Therefore, the present study investigated the long-term effects of varying phosphate concentrations on the marine anammox bacteria, Candidatus Scalindua sp., to identify the optimal range of phosphate. Anammox activity and average growth rates were evaluated under seven phosphate concentrations (0, 0.23, 0.46, 0.68, 1.14, 6.15 [control], and 15.48‍
