Balancing long-term enriched partial denitrifying bacteria and anammox bacteria for carbon-neutral mainstream nitrogen removal

The study involved the long-term stable enrichment cultivation of partial denitrifying bacteria (PDNB). Various environmental conditions were applied to enrich PDNB, and the microorganisms were analyzed according to these conditions. Based on the microbial results, it is possible to determine which environmental factors can aid in the enrichment cultivation of PDNB.
