Bacteria found to naturally break down PCBs   Leave a comment

Polychlorinated biphenyls (PCBs) continue to pollute our environment nearly 30 years after they were banned. We have yet to find an effective means of eliminating these harmful toxins; however, scientists are exploring the possibilities of bioremediation, and are the results are promising.

Construction in ShanghaiBioremediation refers to the use of living organisms and their enzymes to break down contaminants, and restore the natural environment. Soil bacteria found in Shanghai, China have been found to be highly efficient at degrading PCBs. This research comes at a critical time for the residents of Shanghai, where serious PCB contamination has resulted from the major industrial growth over the past few decades. Furthermore, bioremediation provides several benefits over traditional PCB cleanup strategies. According to researchers,

The current approaches to the degradation of PCBs can be divided into heat, chemical, and microbiological. Of these, biodegradation, including microbial degradation and plant degradation, is the most promising strategy because of the relatively low cost and the absence of secondary pollution.
