“…Nevertheless, an optimum operation of an MFC requires that the rate of gas transfer matches the rate of its consumption. Mehta et al (2010) observed a CO consumption rate of 2.1 L (L R day) −1 for an MFC equipped with a sparger, i.e., providing a sufficient membrane area, the K L a values obtained in our tests were sufficient to match the observed CO consumption. Excessive CO transfer might lead to CO-related inhibition of carboxidotrophic organisms (Henstra et al 2007;Sipma et al 2006;Sokolova et al 2009).…”

“…Furthermore, sparger replacement with a membrane offers the advantage of a more compact design. Indeed, the sparger used in the experiments carried out by Mehta et al (2010) required a 50% increase of the anodic compartment. Thus, a membrane-based MFC is expected to have a higher volumetric efficiency.…”

“…Subsequently, Mehta et al (2010) for the first time reported electricity generation in an MFC directly fed with CO or a mixture of CO and H 2 . The MFC technology employs the electricigenic bacteria, which are capable of extracellular electron transfer to an exogenous electron acceptor such as the anode (Logan and Regan 2006;Lovley 2008;L e f e b v r ee ta l .2010).…”

Electricity generation from carbon monoxide and syngas in a microbial fuel cell Hussain, A.; Guiot, S. R.; Mehta, P.; Raghavan, V.; Tartakovsky, B.Contact us / Contactez nous: nparc.cisti@nrc-cnrc.gc.ca. Abstract Electricity generation in microbial fuel cells (MFCs) has been a subject of significant research efforts. MFCs employ the ability of electricigenic bacteria to oxidize organic substrates using an electrode as an electron acceptor. While MFC application for electricity production from a variety of organic sources has been demonstrated, very little research on electricity production from carbon monoxide and synthesis gas (syngas) in an MFC has been reported. Although most of the syngas today is produced from non-renewable sources, syngas production from renewable biomass or poorly degradable organic matter makes energy generation from syngas a sustainable process, which combines energy production with the reprocessing of solid wastes. An MFC-based process of syngas conversion to electricity might offer a number of advantages such as high Coulombic efficiency and biocatalytic activity in the presence of carbon monoxide and sulfur components. This paper presents a discussion on microorganisms and reactor designs that can be used for operating an MFC on syngas.

Improving biofuel yield and water reuse are two important issues in the further development of biorefi neries. An alternative to the typical combustion-based approach to handle residual organics stream by implementation of bioelectrochemical systems such as microbial fuel cells (MFCs) and/or microbial electrolysis cells (MECs) to improve energy recovery from biomass is presented. The potential advantages of this alternative scheme in a biorefi nery include minimization of heat loss and generation of a higher-value product: electricity (in MFC) or hydrogen (MEC). The need for 5-15 gallons of water per gallon of ethanol can be reduced signifi cantly via recycling of water after MEC treatment. Removal of inhibitory byproducts such as furans, phenolics, and acetate in MFC/ MECs to generate energy, thus, has dual advantages: improvements in energy effi ciency and ability to recycle water. Conversion of the sugar-and lignin-degradation products to hydrogen is synergistic with biorefi nery hydrogen requirements for upgrading Fischer-Tropsch (F-T) liquids and other byproducts to high-octane fuels and/or high-value products. Some of these products include sorbitol, succinic acid, furan and levulinate derivatives, glycols, polyols, 1,4-butenadiol, phenolics polymers, etc. Potential process alternatives utilizing MECs in biorefi neries capable of improving energy effi ciency by up to 30% are discussed.
