Long-term effect of pH on denitrification: High pH benefits achieving partial-denitrification

[Display omitted] •Partial-denitrification is a feasible way to supply nitrite for anammox.•Nitrite accumulation rate (NAR) increased with pH during denitrification.•The higher NAR at pH 9.0 was correlated with an enrichment of Thauera.•Thauera harbored more nitrate reductase than nitrite reductase....
