Abstract—The bioremediation of the heavy oil is often limited by acquiring more and more attention. Consequently, it is desired
high viscosity and low bioavailability. The aim of the present that effective remediation technologies with sound
study was to find methods for enhancing rates of heavy oil environmental and economic efficiencies would be developed.
