Abstract:
Electroactive bacteria (EAB) can exchange electrons with conductive materials as part of their metabolic activity, enabling the development of diverse bioelectrochemical systems (BESs). These systems can be used for sustainable power generation, pollutant biosensing, and pollutant bioremediation. Here, we first discuss recent studies that expand the bioremediation and biosensing capabilities of lab-scale BESs by using native and engineered EAB and microbial consortia. Then, we review innovative strategies implemented by large-scale pilot studies and startup companies to scale up BESs for low-cost bioremediation. This review summarizes the complementary insights gained from research done at these different scales and discusses where this knowledge can take us.
