“…Lignin degrading bacteria or fungi, as whole cell or enzymes, such as laccases and lignin peroxidase are used to pretreat LCB. The type of LCB used, the type of chamber and the performance in terms of maximum power density (MPD) of some LCB‐fed MFCs are reported in Table 3 [16,54–66] . Rice straw, corncob, banana peel, lemon peel, canna indica, and sugarcane are some biomass used as the substrate in LCB‐fed MFCs.…”

“…The high MPD of some LCB‐fed MFCs can depend on either a low lignin content in the LCB, such as orange and lemon peels, [62,63] and Sago Hampas, [65] or a strong pretreatment, [16,55] disassembling the biomass. Another way to attain a high performance is the use of a three‐chamber MFC, by coupling the lignolytic and cellulolytic activities of Oscillatoria annae and the electrogenic activity of the coculture of Acetobacter aceti and Gluconobacter roseus [59] . To increase the contact area between LCB and the membrane electrode assembly (MEA), and, as a consequence, to improve the performance, a V‐shaped MFC was also proposed.…”

“…Using a novel three-chamber MFC, Krishnaraj et al achieved a maximum power output of 8.78 W/m 3 at 20.95 A/m 3 and 6.73 W/m 3 at 17.28 A/m 3 with sugarcane bagasse and corn cob as substrates, respectively. However, these output powers are too low to be meaningful for commercial applications [39]. To improve MFC efficiency, a pre-hydrolysis step is often used to obtain monosaccharides or other fermentable compounds, such as degraded phenolic compounds, organic acids including acetic acid from hydrolysis of acetyl group, and furan derivatives such as furfural and 5-hydroymethylfurfural (HMF) from sugar degradation ( Table 1).…”

Conversion of lignocellulosic biomass to electricity using fuel cell technologies is a promising but challenging research topic for sustainable electricity production. This is because that lignocellulosic biomass generally cannot be directly used as a fuel for electricity generation in a conventional fuel cell with high efficiency. Typical fuel cells that can convert lignocellulosic biomass to electricity under mild conditions (< 100 o C) include microbial fuel cells (MFC) and novel direct biomass fuel cells (DBFC) such as that mediated by polyoxometalates (POMs) developed recently. However, the efficiency and power output for these low-temperature fuel cells still need to be improved for practical applications. In this review, we focus on the research advances of electricity generation in fuel cells that can be operated at low temperatures. More specifically, we discussed the progress, challenge and perspectives of biomass-fueled MFCs. Recent interesting researches on DBFC were also highlighted in terms of the efficiency, principles, and technological obstacles. As concluded in this work, lignocellulosic biomass is a promising feedstock for fuel cells because it is renewable, carbon neutral, and sustainable. However, the power density of lignocelluose-fueled MFC are usually far below that required for commercial applications.Improving fermentable sugar release from lignocellulosic biomass and increasing the cell  Corresponding authors: jzhu@fs.fed.us; yulin.deng@ipst.gatech.edu 2 output power are the main research points. DBFC can obtain a high theoretical exergy recovery; however, it is still in its early stage of development with low efficiency. More research should be focused on the electrode development, cell design, parameter optimization, process integration, as well as understanding fundamental process mechanisms.

“…The cellulosic wastes are produced in very large amounts from domestic, industrial and agricultural sources [2,3]. As per the report of the U.S. Department of Energy (2011), total primary residues from agricultural source alone were projected to be 320 million dry tons by 2030 [4].…”

Cellulolytic enzymes are promising candidates for the use of cellulose in any bioprocess operations and for the disposal of the cellulosic wastes in an environmentally benign manner. Cellulases from thermophiles have the advantage of hydrolyzing cellulose at wider range of operating conditions unlike the normal enzymes. Herein we report the modeled structures of cellulolytic enzymes (endoglucanase, cellobiohydrolase and β-glucosidase) from a thermophilic bacterium, Clostridium thermocellum and their validation using Root Mean Square Deviation (RMSD) and Ramachandran plot analyses. Further, the molecular interactions of the modeled enzyme with cellulose were analyzed using molecular docking technique. The results of molecular docking showed that the endoglucanase, cellobiohydrolase and β-glucosidase had the binding affinities of -10.7, -9.0 and -10.8 kcal/mol, respectively. A correlation between the binding affinity of the endoglucanase with cellulose and the enzyme activity was also demonstrated. The results showed that the binding affinities of cellulases with cellulose could be used as a tool to assess the hydrolytic activity of cellulases. The results obtained could be used in virtual screening of cellulolytic enzymes based on the molecular interactions with the substrate, and aid in developing systems biology models of thermophiles for industrial biotechnology applications.
