Abstract: . In this review is presented an innovative technology for use of animal and vegetable waste with high pollution levels in microbial fuel cell (MFC) as an alternative to waste remediation and simultaneously producing electricity and fertilizer for agriculture. A brief history of MFC, the studies about the electron transfer mechanisms, discussion of the biological nanowires in bacteria and the use of chemical mediators or carriers of electrons are explained. The factors influencing the performance of MFCs, the … Show more

“…Protons migrate to the cathode chamber (aerobic compartment) permeating through the proton exchange membrane (thereafter protons combine with oxygen) while the electrons are transferred to the cathode through of an external circuit, with oxygen reduction to water. This electron flow produces an electrical current that can be measured (Rachinski et al, 2010). MFC technology has been used to produce direct electricity from non-sterilized and diluted cheese whey (Antonopoulou et al, 2010), filter-sterilized and diluted cheese whey (Stamatelatou et al, 2011), raw cheese whey, raw cheese whey inoculated with Enterobacter cloacae subspecies dissolvens and heat treated cheese whey inoculated with E. cloacae (Kassongo and Togo, 2010).…”

“…MFCs (Figure 1a) are the most fundamental BESs and have been extensively investigated towards real-world applications [10,11]. With electrochemically active bacteria (i.e., exoelectrogens) such as Geobacter sulfurreducens and Shewanelle putrefaciens on the anode, MFCs are able to generate electrical energy directly from a broad range of biodegradable organics through different redox reactions on the electrodes [12].…”

“…However, despite the continuous progress in using agricultural wastes and wastewater to feed MFCs, the electricity production with these applications is often challenged by the occurrence of other microbial processes such as methanogenesis (i.e., the generation of methane) and ammonification (i.e., the conversion of organic nitrogen to ammonia) [17,55]. In MFCs, the reduction of carbon dioxide to methane in the anode compartment consumes electrons, thus decreasing the Coulombic efficiency and lowering the power generation [10]. Also, high concentrations of ammonia are toxic to most exoelectrogens that power MFCs [63].…”

“…Em geral, a biocélula a combustível é um dispositivo que converte energia química da matéria orgânica em energia elétrica, utilizando a respiração celular de alguns micro-organismos, que podem crescer a partir de substratos renováveis e biodegradáveis. Nela pode acontecer simultaneamente tanto a produção de bioenergia como o tratamento concomitante de resíduos (DANTAS et al, 2013;LA ROTTA et al, 2014;KARATAY et al, 2011;RACHINSKI et al, 2010, ). No entanto, até agora a produção de energia obtida das BCC não é satisfatória.…”

“…(1) Ciclovoltametria: Esta técnica nos permitiu conhecer o comportamento redox dos extratos enzimáticos crus, através da observação do número e a reversibilidade das oxidações e reduções que ocorrem durante cada ciclo (FERNÁNDEZ-SÁNCHEZ et al, 2002;MORANT et al 2013a;RACHINSKI et al, 2010.). As medidas foram feitas numa célula eletroquímica de 25 mL (Figura 1B), de acordo com condições previamente estabelecidas (MORANT et al, 2013a,b;SILVA et al, 2014) …”
