Special Issue Information

Dear Colleagues,

Microbial fuel cells (MFC) can contribute towards for a sustainable future of the wastewater treatment, bioremediation, and biorefineries. Besides convert the energy stored in compounds into electricity, MFC can also transform compounds into less polluting or highly added value ones. New discoveries in the MFC field can not only augment the electricity gain from residual or pollutant substrates, but also enhance the MFC technology for further applications. Therefore, the Special Issue “MFC advances” invites contributions in any aspects related to MFC, such as innovative materials, system designs, microbial communities, biocatalysts interactions, electron transfer, bioremediation, and other related subject to the multidisciplinary field of the MFC.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Fermentation is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Extracellular electron transfer (EET) is key to the success of microbial fuel cells (MFCs). Clostridium sp. often occurs in MFC anode communities, but its ability to perform EET remains controversial. We have employed Clostridium pasteurianum DSM 525 as a biocatalyst in a glycerol-fed MFC, designated MFCDSM. We have also followed the EET of this biocatalyst in the presence of a mediator, namely soluble neutral red (NR), soluble methyl viologen (MV), neutral red film (FNR), or methyl viologen film (FMV). MFCDSM provided power and current densities (j) of 0.39 μW·cm−2 and 2.47 μA·cm−2, respectively, which evidenced that the biocatalyst performs direct electron transfer (DET). Introducing 150.0 µM NR or MV into the MFCDSM improved the current density by 7.0- and 3.7-fold (17.05 and 8.45 μA·cm−2), respectively. After 20 cyclic voltammetry (CV) cycles, the presence of FNR in the MFCDSM anodic chamber provided an almost twofold higher current density (30.76 µA·cm−2) compared to the presence of NR in the MFCDSM. Introducing MV or FMV into the MFCDSM anodic chamber gave practically the same current density after 10 CV cycles. The MFCDSM anodic electrode might interact with FMV weakly than with FNR, so FNR is more promising to enhance C. pasteurianum DSM 525 EET within MFCDSM. Full article
