fate of HPAM, specifically its susceptibility to microbial degradation. Microcosm studies were established to evaluate the biodegradation of HPAM by indigenous oil sands tailings microorganisms under oxic, sulfate-reducing, and methanogenic conditions. Under each redox condition, the ability of

sands process-affected water (OSPW). In order to test the capacity of microorganisms indigenous to MFT for organic compounds removal in OSPW and determine whether they could be extracted from MFT to form biofilm on biofilm carriers, two groups of batch bioreactors were established (1) one treating

. This study demonstrated the feasibility of seeding biofilm reactor with indigenous microorganisms from MFT. The results provide insights on biodegradation of toxic and recalcitrant organic compounds and help the design of continuous bioreactor for OSPW treatment.

treat three different types of oil sands tailings to remove bitumen content. Secondly, biostimulation treatment with acetate of the indigenous tailings microbial community was used to treat the bitumen. The presence of bitumen was found to increase the water toxicity. Analysis of the indigenous tailings

tested to remove the cap water turbidity. C. kessleri addition can remove the cap water turbidity effectively in the bench scale experiment, and nutrient addition can remove a comparable level of turbidity possibly by stimulating the growth of the indigenous algal community. B. braunii didn't achieve any

pit lakes using mudline biofilms that were made up of diverse microbial communities indigenous to oil sands tailings. Mudline biofilms were grown on FFT that was capped with water in 1 L jars. Biofilms reduced turbidity generation by up to 99% during physical mixing experiments, depending on the
