Poly iron sulfate flocculant as an effective additive for improving the performance of microbial fuel cells

Electricity generation from rice bran in microbial fuel cells

“…The mineral solution contained (per liter) 0.14 g of KH 2 PO 4 , 2.5 g of NaHCO 3 , 0.54 g of NH 4 Cl, 0.20 g of MgCl 2 ·6H 2 O, 0.15 g of CaCl 2 ·2H 2 O, 1 mL of a trace element solution, and 2 mL of a vitamin solution (DSMZ medium 318, Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Germany). This solution has been used in previous studies, in which MFCs successfully generated electric power (Miyahara et al 2016a, b). We also examined MFC without adding the mineral nutrients described above (MFC-W), since it has been suggested that rice bran is rich in vitamins and minerals (Faria et al 2012).…”
