Fall 2013
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...

Mullick, A., Morton Sr., M., Thornton, W., Nelson, J.
This report provides a number of cost estimating factors, common terminology and common practices derived from industrial decommissioning projects, international cost estimating practices and the outcome of a joint university, industry and regulator workshop. The cost estimation factors...

This study examines the effects of Pseudomonas aeruginosa (PAO1) biofilm, with a concentration of cells similar to that reported for saturated aquifers, on the transport of poly(acrylic acid) stabilized nanoscale zero valent iron (pnZVI) in 14 cm long, saturated, laboratory packed columns, with...

Fall 2011
Microelectrodes can be used for profiling environmental biofilms. Currently there is no sulfate microelectrode available for studying sulfate reduction in biofilms. In this study, a sulfate microelectrode was fabricated and tested in measurement of environmental biofilms for the first time. The...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

Microbial biodeterioration of human skeletal material from Tell Leilan, Syria (2900 – 1900 BCE)
DownloadSpring 2011
Human bone is considered one of the most direct and insightful sources of information on peoples of the past. As a result, curation protocols have been developed to ensure that the integrity of human skeletal collections is maintained. Although collections are generally considered safe when these...

Productivity and carbon accumulation potential of transferred biofilms in reclaimed oil sands-affected wetlands
DownloadSpring 2011
Biofilms are significant contributors to primary production, nutrient cycling, bio-stabilization and the food web of wetland ecosystems. Photoautotrophic biomass (PB) and primary production (PP) were determined for biofilms exposed to various treatments and materials in wetlands near Fort...

Remediation of bitumen-contaminated sand grains: development of a protocol for washing performance evaluation
DownloadSpring 2010
In the development of a non-aqueous bitumen extraction process, a major obstacle is solvent loss due to hydrocarbon attachment to the reject sand grains. A proposed solution to this problem is to wash (i.e. remediate) the oil-contaminated sand grains with water and surfactants. This research is...

Fall 2009
An agricultural land was adversely affected by salt released by the oil and gas industry. Remediation was needed to recover the land to agricultural productivity. Field-scale and laboratory-scale experiments were conducted to identify a practical and reliable remediation technique that could be...

Melim, Leslie A., Northup. Diana E., Spilde, Michael N., Jones, Brian, Boston, Penelope J., Bixby, Rebecca J.
We report on a reticulated filament found in modern and fossil cave samples that cannot be correlated to any known microorganism or organism part. These filaments were found in moist environments in five limestone caves (four in New Mexico, U.S.A., one in Tabasco, Mexico), and a basalt lava tube...
