NewsBiorefinery uses microbial fuel cell to upcycle resistant plant waste
Researchers have developed a sustainable, inexpensive two-step process that can upcycle organic carbon waste - including lignin - transforming it into antioxidant flavonoids for nutrition and medicine. .By processing waste through a microbe-driven biorefinery, the researchers turned lignin into carbon sources that could be used in high-value, plant-derived pharmaceuticals and ...
