Abstract
The enrichment of anaerobic ammonium oxidizing (anammox) bacteria using upflow anaerobic sludge bioreactor was successfully conducted for 400 days of continuous operation. The bacterial community structure of anammox bioreactor included Proteobacteria (47%), Planctomycetes (25%), Chloroflexi (18%), Chlorobi (8%), and Acidobacteria (2%). All clones of Planctomycetes were affiliated with anammox bacteria, Planctomycete KSU-1 (AB057453). The presence and diversity of ammonia oxidizing bacteria (AOB) and archaea (AOA) were identified by terminal restriction fragment length polymorphism (T-RFLP) based on the amoA gene sequences. The AOB in anammox bioreactor were affiliated with Nitrosomonas europaea cluster. The T-RFLP result of AOA showed the diverse microbial community structure of AOA with three terminal restriction fragments (T-RFs). The Anammox bacteria coupled with AOB and AOA might play a key role in removing high concentration of ammonium nitrogen efficiently in the oxygenlimited.
