The environmental presence of benzene is mostly attributed to anthropogenic activities related to the oil and gas sector and industrial production. While intrinsic bioremediation with microbial organisms is an attractive remediation option due to its minimal maintenance, low cost, and...
Anaerobic biodegradation of hydrocarbons in different oil sands tailings ponds: key microbial players and main activation pathway of hydrocarbon biodegradationDownload
Anaerobic biodegradation of hydrocarbons is an important process in oil sands tailings ponds, which directly affects consolidation of tailings and extent of greenhouse gas emissions from tailings ponds. Since tailings ponds from different operators differ due to extraction process, age of...
Direct interspecies electron transfer (DIET) is the recently discovered microbial syntropy between bacteria and methanogens in anaerobic digestion process that can accelerate the syntrophic conversion of various reduced organic compounds into methane through cell-to-cell electron transfer coupled...
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...
Methanogenesis in oil sands tailings: an analysis of the microbial community involved and its effects on tailings densificationDownload
Densification of tailings slurries to mature fine tailings (MFT) is important in the oil sands industry for tailings inventory reduction, pore water recovery and tailings reclamation. The cause of methane release from the tailings pond of Shell Albian Sands (Albian) and the effects this process...
