“…Moreover, no short chain fatty acids were detected in the bulk liquid, indicating that other organic components were the major components of the organic material present. These results are in line with previous research where long start-up times for Plant-MFCs were recorded with pristine anodes (De Schamphelaire et al 2008;Helder et al 2010;Helder et al 2012). The long start-up times indeed suggest that components derived from rhizodeposition other than small molecules released via direct exudation are more important in current generation by plant-sediment MFCs.…”

Methane (CH 4 ) release from wetlands is an important source of greenhouse gas emissions. Gas exchange occurs mainly through the aerenchyma of plants and production of greenhouse gases is heavily dependent on rhizosphere biogeochemical conditions (i.e. substrate availability and redox potential). It is hypothesized that by introducing a biocatalyzed anode electrode in the rhizosphere of wetland plants, a competition for carbon and electrons can be invoked between electrical current generating bacteria and methanogenic archaea. The anode electrode is part of a bioelectrochemical system (BES) capable of harvesting electrical current from microbial metabolism. In this work, the anode of a BES was introduced in the rhizosphere of rice plants (Oryza sativa) and the impact on methane emissions was monitored.Microbial current generation was able to outcompete methanogenic processes when the bulk matrix contained low concentrations of organic carbon, provided that the electrical circuit with the effective electro-active microorganisms was in place. When interrupting the electrical circuit or supplying an excess of organic carbon, methanogenic metabolism was able to outcompete current generating metabolism. The qPCR results showed hydrogenotrophic methanogens were the most abundant methanogenic group present, while mixotrophic or acetoclastic methanogens were hardly detected in the bulk rhizosphere or on the electrodes. Competition for electron donor and acceptor were likely the main drivers to lower methane emissions. Overall, electrical current generation with BESs is an interesting option to control CH 4 emissions from wetlands but needs to be applied in combination with other mitigation strategies to be successful and feasible in practice.

“…This result was consistent with the previous report that the operation of plant MFC did not influence the plant growth (Helder et al, 2010). The graphite felts at rice harvest remained not significantly damaged.…”

“…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).…”
