Distribution of Nitrobacter and Nitrospira Communities in an Aerobic Activated Sludge Bioreactor and their Contributions to Nitrite Oxidation

Distribution of Nitrobacter and Nitrospira Communities in an Aerobic Activated Sludge Bioreactor and their Contributions to Nitrite OxidationAn analysis of nitrite-oxidizing bacteria in the activated sludge process of a full-scale partially nitrifying wastewater treatment plant revealed Nitrospira and Nitrobacter averaged 1013 cells·L−1 and 1012 cells·L−1, respectively. Correlation coefficients linking shifts in NOB community to operational or environmental variables illustrated Nitrospira were negatively...Author(s)Zhonghua HuangPhillip B. GedalangaBetty H.
