Fig. 2From: Magnet anode enhances extracellular electron transfer and enrichment of exoelectrogenic bacteria in bioelectrochemical systemsVoltage production (a), polarization curves, and power density of MFCs (b) with magnets of 0 mT, 20 mT, 80 mT, and 160 mT as anodes. The scatter plots represent power density (PD) and lines represent voltage curves (V)Back to article page
