Objective:

Project goals include: i) undertaking the cometabolic biotransformation of PCBs in soil from contaminated sites using genetically engineered microbes; ii) design, construct and operate a tilled soil bioreactor (BTSR) to simulate in situ field bioremediation using inoculated organisms in a cycling anaerobic/aerobic bioprocess mode for the biodegradation of PCBs; iii) utilize results from previously funded GLMAC-HSRC projects (using bioaugmentation with various cosubstrates (J.Tharakan's laboratory) and on using engineered PCB congener degrading strains (J.Tiedje's laboratory) for a contained laboratory simulation of field use of these GEMs for PCB bioremediation; and, iv) investigate the biotransformation of the PCBs in contaminated site soil under sequential anaerobic and aerobic conditions in the BTSR.
