Microbial fuel cells using Cellulomonas spp. with cellulose as fuel

A state of the art review on electron transfer mechanisms, characteristics, applications and recent advancements in microbial fuel cells technology

“…The selection of substrate is a very important factor in MFCs, and the proper functioning of the system depends on its nature and biodegradability (58)(59)(60). A study reported maximum electric power of 38.7 mWm −2 , using cellulose as a substrate and Cellulomonas fimi as a biocatalyst (61). Another work investigated variations in power density and microbial community structure in a double-chamber MFC using pig slurry and synthetic wastewater as substrates (62).…”

Lignocellulose, Cellulose and Lignin as Renewable Alternative Fuels for Direct Biomass Fuel Cells

“…Commonly, to produce electricity by cellulose‐fed MFCs a syntrophic bacteria consortium has to be used: cellulolytic bacteria convert the biomass to chemicals that can be used by exoelectrogenic bacteria. The characteristics, operating conditions, and performance, in term of MPD, of some cellulose‐fed MFCs are reported in Table 2 [31–47] . Insoluble cellulose (IC), with few exceptions, [34,35,44] was used as the substrate.…”

“…The characteristics, operating conditions, and performance, in term of MPD, of some cellulose-fed MFCs are reported in Table 2. [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47] Insoluble cellulose (IC), with few exceptions, [34,35,44] was used as the substrate. The most part of studies on cellulose-fed MFCs were carried out using the twochamber configuration.…”

“…To improve the performance of MFC, in some cellulose-fed MFCs Pt was added to carbon, reducing the cathodic reaction activation energy and increasing the reaction rate. [36,39,42,43,45] The high cost and high biological sensitivity, however, are drawbacks for a large scale applications of Pt in MFCs. Ferricyanide is a widely used electron acceptor in microbial fuel cells.…”

Cross-Feeding of a Toxic Metabolite in a Synthetic Lignocellulose-Degrading Microbial Community

“…While the extent of the metabolic capabilities of the genus is not fully characterized-and recent work suggests some species may have the ability to utilize lignin-derived aromatic compounds [23]-we chose to include in our consortium, M. extorquens PA1, a model organism for which extensive metabolic and physiological data exist [21,[24][25][26]. The other bacterial members of this defined community included Pseudomonas putida, a canonical lignin degrader that has been studied extensively for its aromatic catabolism [20,[27][28][29][30], and Cellulomonas fimi, a cellulose degrader of interest for its ability to utilize diverse polysaccharides and to channel the products of their degradation to other organisms in co-culture [31][32][33]. In some experiments, a fourth microbial strain, the oleaginous yeast Yarrowia lipolytica, was included for its ability to grow on organic acids generated by other consortium members, and to produce neutral lipids as a potential end product [33][34][35].…”
