1979
The epilithic microbial and micro-invertebrate communities under conditions of light and shade were studied from April to November 1978. During a period of increasing light intensity from May to June, the level of chlorophyll a (an algal biomass indicator) and numbers of Bacillariophyta in the...

Development of a Novel Engineered Bioprocess for Oil Sands Process-Affected Water and Tailings Fines/Bitumen/Water Separation
Download2014-12-09
Gamal El-Din, M., McPhedran, K., Islam, M.S.
The oil sands bitumen extraction process results in the creation of waste products including oil sands process-affected water (OSPW) and mature fine tailings (MFT). Many technologies are currently under investigation to treat these waste products that are currently contained in vast storage...

Geesy, G. G., Costerton, J. W.
The direct epifluorescence method has been adapted for counting bacteria in the sometimes turbid water of the Athabasca River and this method has been used to quantify planktonic bacteria. Monthly samples over an annual cycle beginning in May 1976 showed this population ranged from 1 x 105 to 2...

Microcosm Evaluation of Community Level Physiological Profiling in Oil Sands Process Affected Water
Download2012-11-02
Eaton, B., Humphries, D., Davies, J.
A microcosm-based experiment was conducted to investigate the ability of community level physiological profiling (CLPP) to detect changes in an aquatic microbial community resulting from exposure to oil sands process affected water (OSPW). Detection of the microbial response was done by using...

Next Generation Sequencing of Protists as a Measure of Microbial Community in Oil Sands Tailings Ponds: Amplicon Versus Metagenomic Approaches
Download2014-11-21
Aquilar, M., Glücksman, E., Bass, D., Dacks, J.B.
The Alberta oil sands provide a major benefit to the province as an economic driver. At the same time, their responsible exploitation, particularly in mitigating the environmental impact of oil extraction stands as a significant challenge to be addressed. One of the most contentious aspects is...

Revegetation of Oil Sands Tailings: Growth Improvement of Silver-berry and Buffalo-berry by Inoculation with Mycorrhizal Fungi and N2-fixing Bacteria
Download1988
The ability of actinorhizal shrubs to tolerate inhospitable conditions while improving soil fertility and organic matter status has led to increased usage of these plants for land reclamation and amenity planting purposes. Silver-berry and buffalo-berry are two such shrubs which are being tested...

Westlake, D. W. S., Coutts, R. T., Nix, P. G., Pasutto, F. M.
In this study, the ability of microorganisms to degrade selected organic substrates in samples of Athabasca River water and water-sediment has been determined. Analysis of laboratory-incubated samples using gas chromatography/ mass spectrometry has shown that trace amounts (100 µg/L) of m-cresol...
