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 ... -
Ammonia-oxidizing archaea in engineered biofiltration systems
(University of Waterloo, 2016-12-21)Ammonia is a nitrogenous metabolic waste product that is produced by all animal life. High concentrations of ammonia are toxic to animals and may result in algal blooms and eutrophication in aquatic environments. To prevent ... -
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 ... -
Impact of water activity on microbial growth in bentonite clay
(University of Waterloo, 2023-08-11)Canada is in the process of designing and implementing a deep geological repository (DGR) for long-term storage of used nuclear fuel. This proposed storage structure will be a multi-barrier system placed 500-800 metres ... -
The mammalian skin microbiome
(University of Waterloo, 2017-08-23)Skin constitutes the primary physical barrier between mammals and their external environment. Characterization of the microorganisms on skin is essential for understanding how a host evolves in association with its microbial ... -
Microbial communities of wastewater in the Canadian Arctic
(University of Waterloo, 2020-01-20)Wastewater management in the Canadian Arctic is challenging due to the extreme climate and lack of conventional treatment system infrastructure. To resolve these issues, most Northern communities use waste stabilization ... -
Microbial Ecology of Phototrophs in Iron-rich Boreal Shield Lakes
(University of Waterloo, 2020-09-24)The early Earth oceans of the Archaean Eon (approx. 3.8-2.5 billion years ago) are thought to have been predominantly anoxic with ferruginous waters containing high levels of dissolved ferrous iron and low levels of sulfate. ... -
Microbiology of Barrier Component Analogues of a Deep Geological Repository
(University of Waterloo, 2020-09-18)Many countries are in the process of designing and implementing long-term storage solutions for used nuclear fuel. Like many of these countries, Canada is considering a deep geological repository (DGR) wherein used fuel ... -
Microbiology of Bentonite Clay
(University of Waterloo, 2020-09-25)Highly compacted bentonite clay has been proposed as an important engineered barrier component of a deep geological repository for Canada’s high-level nuclear fuel waste. As a result, the microbiology of bentonite clay is ... -
Micromeda: a genome property prediction pipeline and web visualization tool
(University of Waterloo, 2020-05-07)Understanding the distribution of biochemical pathways across microorganisms is critical to understanding these organism's evolution, ecology, and industrial applicability. Advances in genome sequencing and pathway databases ... -
Profiling skin-associated archaea and bacteria with 16S rRNA and cpn60 genes
(University of Waterloo, 2021-08-13)As the largest organ of the mammalian body, skin is associated with commensal microorganisms that impact host health. Characterizing host-microbe associations is critical to our understanding of skin health, function, and ...
