Microbial fuel cell (MFC) technology can be employed in order to add value to the metabolic products of acetogenesis fermentation after H 2 production. Considering the total conversion of glucose into acetic acid as the only bioproduct, only 1/3 of the energy available is converted in H 2 from a thermodynamic point of view (Chap. 5). Furthermore, in practical terms, the energy necessary to carry out the pretreatments must be considered as energy used to perform the energy balance, in order to render the organic contents accessible to microorganisms (Chap. 9). Nevertheless, the aim of this book is to focus on anaerobic technology and its energy sustainability; the conversion of H 2 production residues, such as VFA, into additional H 2 or CH 4 or electricity needs to be investigated. Even if the MFC technology is in its infancy, it deserves a very close attention for the possibility of generating electrical energy or additional H 2 . The present chapter is devoted to explore the potential of MFC technology.

“…MEC operated at pH 7 with UTr biocatalyst showed HPR of 1.092 mmol/h and CHP of 3.590 mmol/h and with PTr biocatalyst showed HPR of 1.170 mmol/h and CHP of 4.604 mmol of H 2 . Acid pretreatment of mixed culture suppresses the methanogens so that the produced H 2 is not consumed by the methanogens and H 2 yield is increased simultaneously [17,18]. This might be the reason for more H 2 in the PTr operation compared to UTr.…”

“…pH range of 5.5 to 6 is ideal for effective H 2 production due to the suppression of methanogens [16] and H 2 evolution. Moreover, neutral pH is the optimum condition for many bacterial growth and metabolic activities [18]. At pH 7, electrochemically active bacteria can typically oxidize organic compounds and also effective for H 2 production in single chamber MEC [6,19,20].…”

“…In order to overcome these aforementioned problems and to obtain higher hydrogen yields, considerable research is being carried out to develop advanced technologies viz., microbial electro-hydrogenesis that can minimize environmental catastrophe [2,[10][11][12][13]. Microbial electro-hydrogenesis which is a type of electro-fermentation process provides a completely new approach for H 2 generation from bio-waste and wastewater, accomplishing simultaneous waste treatment [3,4,14]. Microbial electrolysis process has the potential of electro-fermenting a wide variety of dissolved organic matter present in the wastewater and secondary effluents to H 2 with an input of small amount of electric current [4,[15][16][17].…”
