Biodegradation of crude oil using an efficient microbial consortium in a simulated marine environment

► This paper provided a more detailed investigation about the escalation experiment. ► The crude oil degradation rate could reach up to 79% at 25 °C in 3.0% NaCl solution in the flask trial. ► Over 51.1% of TPH were degraded at the oil concentration of 0.5 L/m2 in mesocosm experiment. ► The esocosm experiment was a primary exploration in forming a common investigation method.
