“…Although theoretically the charges of BES are balanced in a silicate free BES system by transport of the protons through PEMs (Fig. 2.4d), without the presence of a buffer solution an obvious difference in pH of the anodic (acidic) and cathodic (alkaline) chambers have been reported (Du et al, 2007;Gil et al, 2003). This is because the proton production rate in the anodic chamber is higher than proton transport and consumption rate in the cathodic chamber 20 (Gil et al, 2003).…”

“…Even though the highest current values in BES were achieved at pH values of 7-8 in the first (anodic) chamber, depending on the organisms used the pH can vary between 5 to 9 (Gil et al, 2003). The cathodic chamber was reported to operate within pH range of 7 to 9.…”

This is because the proton production rate in the anodic chamber is higher than proton transport and consumption rate in the cathodic chamber 20 (Gil et al, 2003). Alkaline silicates can alleviate the need for additional buffers that are commonly added to the anode chamber to adjust the pH (Du et al, 2007).…”

“…Thus, one main reason for conclusion of these compounds from the angle may be as respiratory inhibitors or toxins emancipation (Hernandez et al, 2004;Voggu et al, 2006). Additionally, multifarious types of electron mediators were applied in MFC to improve the electron transfer efficiency while they are conventionally high-priced and not applicable to be used in commercialscale and they can be noxious to living organism for extendable lifetimes (Gil et al, 2003). The goal of the present research was to ascertain MFCs for power generation using the treated whey as substrate with the least operational manipulation and four cathodic electron acceptors (catholyte).…”

While oil prices raise and the supply remains unsteady, it may be beneficial to use the high content of energy available in food processing wastes, such as cheese whey waste, by converting it to bioenergy. As well, there have been many new waste biotreatment technologies developed recently, which may well be used directly to food processing wastes. Microbial fuel cell represents a new technology for simultaneous use of waste materials and bioelectricity generation. In this study, bioelectricity generation with whey degradation was investigated in a twochamber microbial fuel cell with mediators. E.coli was able to use the carbohydrate found in whey to generate bioelectricity. The open-circuit voltage in absence of mediator was 751.5mV at room temperature. The voltage was stable for more than 24 h. Riboflavin and humic acid were used as conceivable mediators. The results showed that humic acid was a few times more effective than Riboflavin. Additionally, four chemicals employed as catholyte. Based on polarization curve, FeCl 3 (É É É) was the best. Maximum power generation and current were 324.8 ì W and 1194.6ìA, respectively.

Microbial fuel cells (MFCs) are a hybrid bioelectrochemical system, which converts biosubstrates directly into green electricity by effectively oxidizing them using bacteria under ambient temperature/pressure condition. The potential, developed between the bacterial metabolic activity and electron acceptor, was separated by a membrane manifesting bioelectricity generation. The achievable power output from MFCs has increased remarkably by modifying their system designs, such as optimization of the MFC configurations, their physical and chemical operating conditions, and their choice of biocatalyst. More recently, selecting the proper materials, such as the anode‐cathode electrodes and a proton exchange membrane (PEM), is one of the critical challenges for applications of MFC. The specific materials for each chamber used in MFC can affect the power density and Coulombic efficiency. Furthermore, the practical applications of MFC technologies include renewable electricity generation, wastewater treatment, biological oxygen demand (BOD) sensor, and implantable medical devices.
