TL;DR: It is analyzed how growth of bacterial populations was stimulated by acetate or methanol as the external carbon source in nitrogen-removal systems and characterized nitrite reductase genes (nirS and nirK) as functional marker genes for denitrifier communities in acetate- or meethanol-assimilating populations.

TL;DR: In this paper, the effects of an anoxic period on N2O emission and nitrogen removal were investigated in an actual domestic wastewater treatment plant, and the results showed that an optimum combination of aerobic and anoxic conditions and their suitable control are very important for improving nitrogen removal efficiency and controlling N 2O emission.

TL;DR: Both laboratory and field observations suggest that the N : P supply ratio and temperature are significant environmental factors affecting the relative abundances of A4.

TL;DR: The biofilm reactor showed similar patterns to those of the non-biofilm reactor in track behavior, but the former was more effective in the reduction of N2O emissions, which was significantly influenced by residual NO3-, increasing monotonically as the concentration of NO3- in the reactor increased.

TL;DR: It is concluded that the mlrA gene is conserved in three different bacterial species, and it is unique to microcystin degraders but not to the genus Sphingomonas.
