The Effect of Corrinoid Co-factors on Bioremediation of Chlorinated Compounds
Research Brief - March 2016
Specific modifications to helper molecules, or co-factors, play an important role in how efficiently some bacteria can degrade toxic chlorinated pollutants. In a new study, researchers from the University of Tennessee found that specific chemical modifications to corrinoid co-factors, a group of molecules that includes vitamin B12, can affect how well bacteria degrade chlorinated pollutants such as tetrachloroethene (PCE) and trichloroethene (TCE).
