Oil sands surface mining operations in northeastern, Alberta, Canada produce enormous volumes of fluid fine tailings, an aqueous suspension of fine clays, sand, unrecovered bitumen, and diluent hydrocarbons. The tailings are deposited and retained on

Microbial metabolism of fugitive hydrocarbons produces greenhouse gas (GHG) emissions from oil sands tailings ponds (OSTP) and end pit lakes (EPL) that retain fluid tailings from surface mining of oil sands ores. Predicting GHG production, particular

Tailings produced from surface-mined oil sands ores are retained in ponds on-site, pending water recovery for re-use and reclamation of solids. To enhance dewatering of tailings, we previously demonstrated that incubation of mature fine tailings (MFT

Bitumen extraction from oil sands ores generates enormous volumes of fluid tailings in on-site repositories where slow consolidation of suspended solids and porewater recovery hamper tailings reclamation. Here, we demonstrate proof-of-concept where m

Summary Iso-alkanes comprise a substantial proportion of petroleum and refined products that impact the environment, but their fate is cryptic under methanogenic conditions. We investigated methanogenic biodegradation of C7 and C8 iso-alkanes found i

Hydrocarbon-contaminated soil and groundwater at oil and gas production sites may be additionally impacted by salts due to release of produced waters. However, little is known about the effect of salt on the in-situ biodegradation of hydrocarbons by

A methanogenic short-chain alkane-degrading culture (SCADC) was enriched from oil sands tailings and transferred several times with a mixture of C6, C7, C8 and C10 n-alkanes as the predominant organic carbon source, plus 2-methylpentane, 3-methylpent

Studies have been carried out using a defined bacterial consortium which degrades crude oil under cold, marine conditions. The type of nitrogen supplement (i.e. ammonium versus nitrate) in the artificial sea water medium used in the experiments affec
