Achieving an understanding of the biodegradation of organic sulfur compound(s) (OSC) in crude oils has been hampered by limitations in separation methods and analytical techniques. In this study, a simulated aerobic biodegradation experiment was performed on a sulfur-rich crude oil, from which a series of biodegraded oils from slight to moderate degrees of biodegradation were obtained. Molecular transformations...
In this study, an in situ biological two-layer permeable reactive barrier system consisting of an oxygen-releasing material layer followed by a biodegradation layer was designed to evaluate the remediation effectiveness of MTBE-contaminated groundwater. The first layer containing calcium peroxide (CaO 2 ) and other inorganic salts is to provide oxygen and nutrients for the immobilized microbes...
