Cooperative microorganisms in nitrification-denitrification sludge as the hidden helper for rapid anammox enrichment.
Nitrification-denitrification sludge is widely used as the seed sludge for anammox bacteria enrichment, yet little is known about which microorganisms it harbors can metabolically support the growth of anammox bacteria. This study focused on exploring the above-mentioned issue during the enrichment of anammox bacteria...
