“…This technology is often called plant microbial fuel cells (PMFC), in which root exudates containing organic compounds are oxidized by electrochemically-active rhizosphere bacteria at the anode. [62] Oxygen reduction occurs at the cathode which is separated from the anode by soil that acts as a membrane, enabling the conversion of chemical energy stored in rhizosphere exudates to bioelectricity. Several studies confirmed that structural design of the double-chambered architecture of the PMFC, [63] application of graphene oxide as anode nanomaterial, [64] as well as modification of floating macrophyte ecosystem with Eichhornia crassipes [65] or Spartina anglica [66] can lead to an improvement in the power output to 469 mA m −2 .…”

“…For large scale application, Plant-MFC is potentially integrated in wetlands by which various functions could be combined including electricity generation, sediment remediation, plant growth support, and as protection of coastal areas [23,29].Plant-MFCs were embedded with vascular plants, macrophytes, and bryophytes as well as their combination with sediments, natural and constructed wetlands. From a recent review paper, at least 40 plant species have been utilized in the Plant-MFC system [30]. Among those species, Spartina anglica is one of the most model species [20,21,25,28,31,32].…”

“…In a Plant-MFC anode, oxidation may occur from different sources. Plant rhizodeposits include exudates (sugars, organic acids), secretions(polymeric carbohydrates and enzymes), lysates(dead plant cell materials) that are potentially available are oxidised by the EAB and other root-associated microbes to yield electrons [54]. In addition, also other soil redox processes also occur, like sulphide can be anaerobically oxidized to elemental sulphur (S 0 ) and SO4 2by phototrophic sulphur bacteria (Chlorobium spp.)…”

“…Therefore, we foresee that implementation of Plant-MFC should be based on this characteristic. Other prospective applications of Plant-MFC are described in an overview paper like: application can be combined with wastewater treatment, remediation of polluted sediments and surface water, greenhouse gas mitigation and bio sensing [54]. There are also devices available in the market that are powered by Plant-MFC technology such as Sprout 'n Spark, Plant-e clock, and Living Light [66].…”
