“…Bacteroidetes not only metabolize saccharides and protein but also participate in denitrication under anoxic conditions. 27 The different acclimation modes gave rise to the signicant change in the abundance of Candidatus saccharibacteria in the three samples. However, the abundance was only 5.35% in sample R1.…”

“…Apart from removing carbon, Bacteroidetes and Chloroflexi also contributed to nitrogen removal by denitrification [33,34]. Different from the three phyla above, the relative abundance of Actinobacteria increased from 11.2% in S0 to 15.0% in S1.…”

A sequencing batch reactor (SBR) with an intermittent aeration mode was established to achieve partial nitrification (PN) and the short-term effects of C/N ratios were investigated. Stable nitrite accumulation was achieved after 107 cycles, about 56d, with the average ammonia nitrogen removal efficiency (ARE) and nitrite accumulation rate (NAR) of 96.92% and 82.49%, respectively. When the C/N ratios decreased from 4.64 to 3.87 and 2.32, ARE and NAR still kept a stable and high level. However, when the C/N ratio further decreased to 0.77, nitrite accumulation became fluctuation, and ARE, total nitrogen (TN), and chemical oxygen demand (COD) removal performance declined obviously. Except for four common phyla (Proteobacteria, Bacteroidetes, Chloroflexi, and Actinobacteria) in the wastewater treatment system, Patescibacteria, the newly defined superphylum, was found and became the most dominant phylum in the PN sludge for their ultra-small cell size. The only ammonia oxidation bacteria (AOB), Nitrosomonas, and nitrite oxidation bacteria (NOB), Nitrospira, were detected. The relative abundance of NOB was low at different C/N ratios, showing the stable and effective inhibition effects of intermittent aeration on NOB growth.

“…The simultaneous nitrification and denitrification (SNDN) performance was examined under limited DO in a novel asynchronous periodic reversal bio-electrocoagulation system for a submerged MBR (Li, Dong, Dong, Qian, Hu, & Ye, 2018). Results for 1.2 mg/L DO run indicated that electrocoagulation improved TN removal from 59.48% to 75.09%.…”
