Mercury is a neurotoxic heavy metal with the ability to biomagnify, therefore it is a significant issue in public health and environmental studies worldwide. Its levels are continually on the rise due to copper, nickel, and gold mining activities, the industrial use of mercury catalysts, mercurial fungicides in agriculture, and the burning of fossil fuels. This has resulted in the pollution of many marine ecosystems and water reservoirs worldwide, the cleanup of which using current technology, is either not feasible or incredibly costly. This study describes the use of engineered recombinant bacteria to facilitate the biological remediation of the neurotoxin methylmercury and hazardous mercury ions from an aquatic target site into less toxic form. This synthetic microbe was incorporated in novel encapsulation technology within a cost-effective, scalable water filtering column. The employment of this device could rigorously change the practices used in mercury decontamination efforts as well as pave the way for the switch to biological rather than chemical processes. Furthermore, this technology can be applied towards bioremediation and biosensing of various other heavy metals and organic toxins in the environment.
