Ammonia-oxidizing archaea and complete ammonia-oxidizing bacteria in a municipal wastewater treatment plant
(University of Waterloo, 2018-09-25)High levels of ammonia in aquatic environments can lead to eutrophication, oxygen depletion, and toxicity to aquatic animals. An important goal of municipal wastewater treatment plants (WWTPs) is to remove ammonia from ... -
Distribution and Function of Soil Thaumarchaeota
(University of Waterloo, 2018-08-17)Despite the importance of ammonia-oxidizing archaea (AOA; Thaumarchaeota) to soil nitrification (Chapter 1), their biogeography in terrestrial environments and relative contributions to nitrification remain unclear. ... -
Enrichment and activity of comammox Nitrospira from the rotating biological contactors of a municipal wastewater treatment system
(University of Waterloo, 2021-02-05)Nitrification, the biological conversion of ammonia to nitrate, via nitrite, is an important process in both natural and engineered systems. Nitrification within wastewater treatment plants (WWTPs) is necessary because ... -
An Investigation of Nitrification Predictors and Factors in Two Full-Scale Drinking Water Distribution Systems
(University of Waterloo, 2012-01-10)The biologically-mediated process of nitrification can occur in chloraminated drinking water distribution systems. In this process, ammonia is oxidized to nitrite by ammonia-oxidizing bacteria (AOB) and archaea (AOA). In ... -
Paradigm Shift: Does River Metabolism Mask the Isotopic Signal of Nitrate Sources?
(University of Waterloo, 2017-05-19)Nitrate (NO₃⁻) is the most ubiquitous contaminant in surface and groundwaters in Canada. Synthetic fertilizer application and manure production in intensive agricultural areas contribute large quantities of NO₃⁻ to the ...
