Microbial Electrochemical Process for Bioremediation of Recalcitrant Contaminants in Soil and Water
Bongkyu KIM,Mirella Di LORENZO,In Seop CHANG 한국생물공학회 2021 한국생물공학회 학술대회 Vol.2021 No.10
Environmental pollution that has exceeded the self-purification capacity of nature requires artificial support, which incurs a lot of economic cost and labor. For the potential solution, a bioremediation process based on ecofriendly, sustainable, and low-cost microbial electrochemical system could be used. In the study, we introduce a microbial electrochemical bioremediation for contaminated soil and water. For bioremediation of contaminated soil by pesticide, a soil microbial fuel cell which can harvest electricity while promoting biodegradation of a selective pesticide called Atrazine was developed, and the direction for scale-up for field application of the proposed system was discussed. For water, a study for concurrent harvesting electrical energy and recovering useful resource from a mineral rich wastewater was developed with linked process of microbial fuel cell and chemical precipitation. The study aims to explain the potential of microbial electrochemical bioremediation for contaminated environment with generation of renewable energy and removal of recalcitrant pollutant, towards a promising sustainable environmental biotechnology.
