Electrochemical performance and microbial community profiles in microbial fuel cells in relation to electron transfer mechanisms

Abstract: BackgroundMicrobial fuel cells (MFCs) operating with complex microbial communities have been extensively reported in the past, and are commonly used in applications such as wastewater treatment, bioremediation or in-situ powering of environmental sensors. However, our knowledge on how the composition of the microbial community and the different types of electron transfer to the anode affect the performance of these bioelectrochemical systems is far from complete. To fill this gap of knowledge, we designed a se… Show more

“…CV peaks that may indicate a cytochrome mechanism (Bewley et al, 2013) are present in our data. Other archaea show some evidence of EET capability (Uria et al, 2017). Particle size and coccoid morphology observed by SEM are also consistent with Nanoarchaeota members (Huber et al, 2003).…”

“…This technology has become an important technical means for studying microbial diversity and community structure in the environment [30]. The technology can explain the diversity of microorganisms in a particular ecosystem [31]. In this study, the method described in Section 2.4 was used for microbial diversity determination with the NaCl and ectoine concentrations of 30 g L -1 and 1 mmol L -1 respectively, in the MFCs substrate.…”

“…The presence of Methylophilus also suggests that some methanol can be oxidized using diffused oxygen as an electron acceptor through Methylophilus activity. Arcobacter is a known microaerobic exoelectrogen commonly found in acetate-fed MFCs [53,54]. Acetobacterium is an acetogenic genus known to convert methanol into acetate through acetogenic fermentation [55,56].…”
