Electricity generation by a plant microbial fuel cell with an integrated oxygen reducing biocathode

Electricity generation and recovery of iron hydroxides using a single chamber fuel cell with iron anode and air-cathode for electrocoagulation

“…There are four main peaks, and the trends associated with these Raman bands were similar. Based on previous reports [SI [1][2][3][4][5][6][7], the Raman bands marked in bold numbers in SI Table 1 were peaks associated with iron oxides. These results suggest that a few similar key iron oxides were produced at the iron anode, air cathode, and in the solution.…”

“…Aided by microbes, MFCs are capable of converting the chemical energy stored in nearly all chemical compounds to electrical energy [1][2][3][4][5]. Over the last decade, various configurations of MFCs have been developed including single chamber MFCs, dual chamber MFCs with membranes, tubular MFCs, plate MFCs, and stacked MFCs [6][7][8][9][10].…”

Microbial community structure accompanied with electricity production in a constructed wetland plant microbial fuel cell

“…Other species including Glyceria maxima, Spartina anglica, Arundinella anomala, Lemna minuta, and Arundo donax have been studied in PMFCs and showed current production associated with plant rhizodeposits (Helder et al, 2010(Helder et al, , 2012aHubenova and Mitov, 2012;Strik et al, 2008;Timmers et al, 2010Timmers et al, , 2012Wetser et al, 2015). Power production has been improved through the optimization of plant selection, reactor configuration, or nutrient media (Chen et al, 2012;Helder et al, 2012a,b;Moqsud et al, 2014;Wetser et al, 2015). However, so far very few studies investigated how exactly the microorganisms interact with plants, especially for substrate and nutrient exchanges, because most studies used acetate or other nutrients in the enrichment media, which resulted that microbes utilize these readily available substrates rather than the organics derived from rhizodeposits.…”

A Radio-Triggered Wireless Sensor Platform Powered by Soil Bacteria

“…We demonstrate the feasibility of collecting environmental parameters and sending information when requested by a data aggregator thank to a radio-trigger circuit exploiting only the energy harvested from a microbial environment [8]. The combination of Microbial Fuel Cell technology (MFC) as an energy supplier and a smart wake-up system [9] to activate the platform, makes this system suitable for pervasive and continuous sensing applications.…”
