Resumen

The use of antibiotics to treat bacterial infections has been one of the most significant breakthroughs in modern medicine. However, drug resistance is increasingly threatening the efficacy of the current repertoire of antimicrobials. The search for novel classes of antimicrobials from microbes in varied natural environments has become a useful approach to this issue. The topic of my thesis is to study the resistome and the microbial composition of deep soil samples collected from the Vancouver campus of UBC, and to use these soils in the isolation of Actinobacteria with the potential of produ

Resumen

This thesis is an accumulation of work regarding the role of phosphorus (P) and water in soils in relation to crop growth and food production. We use a multiscale modelling approach to initially capture the interactions of soil and water on a single cylindrical root and further expand to a growing root structure. Moreover, we have a multi-physics problem involving fluid dynamics of water uptake in plants, and reactive solute transport in the soil for plant P uptake. We use detailed climate data and the super computer at the University of Southampton (Iridis 4) to parameterise our models. These

Resumen

The Atacama Desert of northern Chile is one of the most arid regions on Earth. The central plateau, between the coastal escarpment and the Andes, is devoid of vegetation and receives only millimeters of rain every few years. Though plants are absent in the soils of this desert, perhaps bacteria can survive, and even thrive, in these hyperarid conditions. This dissertation represents the first comprehensive study of bacterial diversity in the driest central latitudes (approximately 24°S) of the Atacama Desert.

Resumen

The microbial life in the soil is essential for providing a functioning habitat for plants to grow. A literature study was conducted to investigate the knowledge and science behind soil biology. The purpose of this study was to define what is soil health and how it is influenced by the soil microbial communities. The literature study concluded that the ability of soil biology to benefit plants includes a variety of aspects. Nutrient availability, soil structure and pest resistance are all greatly influenced by soil microbes. To practically examine these theories, an experiment was conducted w

Resumen

Arsenic contaminated soil is one of the major arsenic sources for potential harmful ecological impact on living organisms. Phytoremediation using viable plant species is an emerging, biological technology for the removal of toxic contaminants from soil. Although hyperaccumulating plants and plant varieties are known, there is still a need to find new (and preferably local) plant species for phytoremediation. The aim of this study was to investigate the germination and growth of two grass species common in the northern Fennoscandia with respect to the influences of high concentration arsenic

Bioaugmentation with C. testosteroni BR60 increased 3-CB degradation at both contaminant levels, and the increase was more pronounced at the higher level due to contaminant inhibition of indigenous 3-C

Traditional agricultural practices often result in gaseous losses of nitrous oxide (N2O), ammonia (NH3), and carbon dioxide (CO2), representing a net loss of nutrients from agricultural soils, which negatively impacts crop yield and requires farmers to increase nutrient inputs. By adopting best management practices (BMPs; i.e., no-tillage, cover crops, sub-surface manure application, and proper manure application timing), there is great potential to reduce these losses.

Resumen

Microbial-based strategies were investigated for eventual bioremediation of petroleum hydrocarbon-contaminated, acidic soils from Resolution Island (RI), Nunavut. A biotreatability assessment phase one study determined that supplementation of soil with commercial fertilizer and lime enhanced hydrocarbon mineralization. Phase two applied these conditions to large scale mesocosm trials, containing ~150 kg soil, incubated in a temperature cycle that represented the ambient summer conditions on RI (10 d of 1°C - 10°C for 60 d)
