Bioremediation is one of the most popular and cost-effective options for site restoration. However, knowledge related to bioremediation is very complicated and often difficult to learn. This course will be an introduction to bioremediation of hazardous wastes (BHWs). The primary objectives of the course are to: 1) provide a sound understanding of the principles, applications and limitations of BHWs; 2) develop the course attendees' ability to design some bioremediation systems; and 3) enhance the course attendees' capability to identify major issues related to bioremediation. Sixteen lectures (each 45 min) will be given via Zoom. Upon taking the course, the attendees will understand key concepts of bioremediation, fate and transport of hazardous wastes in subsurface environments, fundamentals of microbiology that is related to microbial energy, metabolic pathways and microbial transformation of hazardous materials, redox reaction and mass requirement for electron accepter and nutrients in bioremediation processes, sorption/desorption and bioavailability of hazardous wastes, in-situ, on-site and extra-site bioremediation in different phases (e.g., solid, liquid and vapor-phase bioremediation). The course will be planned/offered as per the norms set by Sichuan University for BHW subject. Senior undergraduate/fresh graduate students are welcome to take the course in the summer.
