Microbial Ecology and Kinetics of Chlorinated Aliphatic Solvent Biodegradation

Project Title: PECASE: Integrated Modeling and Experimental Evaluations of Competition between PCE-Dehalogenating Populations: Implications for In Situ Bioremediation

Funding: National Science Foundation

Description:

When multiple dehalorespiring populations are present, several competitive (or complementary) interactions may occur and affect the outcome of bioremediation (Becker, 2006).

The inhibitive effects of chlorinated solvents on complete detoxification of the contaminants may also be compounded in cultures containing multiple dehalorespiring populations (Lai and Becker, 2013)
