Study finds that native microbes biodegrade longer-chain hydrocarbons in oil sands tailings to methane; implications for management of tailings and GHG emissions from tailings ponds

Green Car Congress

Proposed anaerobic hydrocarbon biodegradation pathways in oil sands tailings. The researchers now report that higher molecular weight n -alkanes (C 14 , C 16 , and C 18 ) are also degraded under methanogenic conditions in oil sands tailings, albeit after a lengthy lag (180 days) before the onset of methanogenesis.
