Abstract To optimize the efficiency of bioremediation, treatability studies are needed to understand the fate of pollutants and environmental conditions under which microorganism growth is promoted and efficient degradation of these pollutants result. This article presents a recommended procedure which may achieve these goals. Results and treatability comparisons for candidate compounds including carbon tetrachloride (CT), methyl-tert-butyl-ether (MTBE) and hexachlorobutadiene (HCBD) are presented and discussed. Culture redox potential (ORP) which is an indicator or free electron activity of a system appeared to have a significant impact on CT biodegradation. Optimum biodegradation of CT by Pseudomonas cepacia was observed between -100 and -200mv. Under the optimum environmental conditions established during the batch-scale biotransformation study, 98 to 99.9% of CT and 70% of MTBE introduced into the continuous fixed-biofilm reactor were degraded. The biphasic model simulating biodegradation of CT and MTBE provided an excellent correlation in the fixed-biofilm study and was simple to apply as compared with other models.
