Microbial Fuel Cells (MFCs) are bio-electrochemical devices that use the power of respiring microbes to convert organic matter into electrical energy. Thus, they can help treat wastewater and also generate electricity. Realising the vast potential these cells have, scientists are finding ways to improve their performance and efficiency.
Researchers have identified urban sewage as a critical hotspot for the evolution and spread of drug-resistant bacteria, highlighting an urgent need for nationwide wastewater monitoring to prevent future health crises.
