The Occurrence of Residual Biological and Chemical Hazards in Recovered Struvite from Blackwater
DownloadFall 2018
Phosphorus is an essential element in several industries such as agriculture and a requirement for growth. Dwindling phosphate rock sources thus requires the security of new phosphorus sources to maintain future populations. On the other hand, wastewater contains a considerable amount of...

The ecology of boreal forest floor microbial communities in relation to environmental factors
DownloadFall 2012
Soil microbial communities in boreal forests are structured by complex interactions among many factors operating simultaneously on large and small spatial scales. Of particular note in the boreal mixedwood, the microbial communities under trembling aspen and white spruce forest floors are...

Bacterial conjugation is the process of plasmid DNA transfer from a donor cell to a recipient cell. This process is mediated in F-like plasmids by proteins expressed by the tra operon. The relaxosome forms at oriT (origin of transfer), where the nicking and unwinding of a single-stranded copy of...

The inactivation fluence of a target wastewater plant in Alberta, Canada was determined in the laboratory and was found to be close to that reported by the target wastewater plant. The effect of inactivation fluence, effective reactivation fluence, temperature, and river water on the percent...

Infectious respiratory diseases, caused by viruses and bacteria that attack the respiratory system, constitute a serious threat in public health around the world. Pathogens can be transmitted in the air though large droplets or aerosols. As aerosols can linger in the environment for a prolonged...

A bacterial colony constitutes a complex microcosm which is equipped with a wide range of defensive adaptations that allow the colony to survive adverse environmental conditions and predation. The extreme resilience of bacteria in colonies has been a subject of continued research for nearly two...

Removal of model waste-water bacteria by magnetite in water and waste-water treatment processes
DownloadFall 2012
Conventional disinfection processes used for water and waste-water treatment such as chlorination, and ozonation produce disinfection by products which are carcinogenic. The use of magnetite as an alternative method of removing pathogenic microorganisms from the water streams was proposed as it...

Regulation of digestive tract and progenitor cell homeostasis by intestinal bacteria in Drosophila melanogaster
DownloadFall 2020
The digestive tract facilitates nutrient uptake in the presence of a heterogenous cohort of symbiotic microbes. These microbes along with their collective genetic material form the intestinal microbiome and contribute to animal phenotypes. Similar to mammals, the microbiome of insects forms a...

Methanogenesis in oil sands tailings: an analysis of the microbial community involved and its effects on tailings densification
DownloadSpring 2010
Densification of tailings slurries to mature fine tailings (MFT) is important in the oil sands industry for tailings inventory reduction, pore water recovery and tailings reclamation. The cause of methane release from the tailings pond of Shell Albian Sands (Albian) and the effects this process...

Collins, Catherine Elizabeth Victoria
Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...
