“…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.…”
