A fungal microbial fuel cell using Mucor pseudolusitanicus converted sugar industry waste into electricity, reaching 47.3 mW/m² power density and 310.9 mA/m² current while simultaneously reducing pollution load by 67%. Voltage peaked around ~156 mV within the first week as fungi rapidly consumed simple sugars, then stabilized as they shifted to breaking down tougher plant material. Fungi can clean up high-pollution waste streams while generating usable energy, especially in low-infrastructure industrial settings.
