Microbial adaptation, differentiation, and community structure
Microbes play a central role in diverse processes ranging from global elemental cycles to human digestion. Understanding these complex processes requires a rm under- standing of the interplay between microbes and their environment. In this thesis, we utilize sequencing data to study how individual …

Microbial adaptation to dissolved organic matter in freshwater ecosystems
… DOM sources and assess the implications of these adaptations for how the DOM is degraded. Chapter 1 provides an overview of the sources and fate of dissolved organic matter in freshwater ecosystems, with a particular focus on the critical role that microbes play in the degradation of DOM and the …

The Impact of Dietary Fat and Phosphatidylcholine on Increased Trimethylamine-N-oxide Levels
… Releasing of TMA moieties is dependent on the adaptation of the gut microbiota to dietary TMA containing substrates such as phosphatidylcholine (PC), choline, and L-carnitine. A high-fat diet is an environmental risk factor that may increase TMAO production. However, it isn’t clear if the high …

Investigating factors affecting the anaerobic digestion of seaweed: modelling and experimental approaches
… in the presence of other process inhibitors. Microbial adaptation to salinity was also investigated during batch assays. It was found that a suitable period of adaptation can significantly reduce the adverse effect of salinity on methanogens. The phenomenon was successfully implemented in the …

Elucidating the Molecular Pathways Involved in the Fitness and Water Stress Response of Pseudomonas synxantha 2-79 in the Plant Rhizosphere
… surprisingly arid conditions. The molecular adaptation of 2-79-like bacteria to plants growing in dry soils is poorly understood. We hypothesized that the ability of 2-79 to colonize and persist in the rhizosphere of water-stressed plants is underpinned by the formation of hydrating biofilms …

Isolation of antimutator yeast strains: an exploration of DNA replication fidelity
… that transient mutator phenotypes promote microbial adaptation and mammalian oncogenesis.

Elucidating microbial interactions, adaptations, and evolution under extreme environmental conditions in modern microbial mats from Shark Bay, Western Australia
Fossilized microbial mats dating back 2+ Ga record some of the earliest evidence of life on Earth. These ancient pustular mats preserve evidence of microbial production of extracellular polymeric substances (EPS), revealing the potential importance of EPS in the protection and preservation of these …

Genomics-Based Characterization of the Microbial Community and Plasmidome of the Regina Wastewater Treatment Facility and the Surrounding Aquatic Environment
… for the production of energy or increasing microbial biomass. The activated sludge environment is a complex microbial ecosystem, containing stable populations of organisms adapted to activated sludge, as well as transient environmental and human gutassociated organisms. These microbial …

Mechanisms of microbial-host interaction during asymptomatic bacteriuria
… an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. Patients with asymptomatic bacteriuria (ABU) are protected …

Investigating human pharmaceutical compounds present in municipal and hospital wastewaters and options for their removal
… and naproxen under both conditions; longer microbial adaptation periods for these two compounds were probably required. The most important factor affecting the removal of the compounds was the SRT. Therefore, the conclusion was drawn that combining anaerobic and aerobic systems with longer …

Automated Plant Morphological Assessment and Microbial Community Monitoring in Simulated Lunar Regolith
… on Mizuna mustard growth while assessing microbial community diversity and functionality. To support this effort, a custom software pipeline utilizing an open-source library, PlantCV, was developed to automatically track plant leaf area and height via image analysis. Results indicated that …
