Electron transfer mechanisms underlying magnetite-mediated nitrate removal in electro-assisted mixotrophic denitrification for recirculating mariculture wastewater treatment.
Efficient nitrate removal from recirculating mariculture wastewater is constrained by low carbon-to-nitrogen ratio and high nitrate concentrations. Although mixotrophic denitrification can integrate organic- and sulfur-driven pathways, its performance is still limited by inefficient electron transfer and poorly coordin...
