Microbial Transformation and Degradation of Toxic Organic ChemicalsLily Y. Young, Carl E. Cerniglia Microorganisms offer a more effective and economical means of reducing or eliminating environmental contamination than more traditional treatment methods. This study examines the role of microbes in the degradation of toxic organic chemicals. |
