A white-rot fungus is used as a biocathode to improve electricity production of a microbial fuel cell

Isolation and characterization of a novel electricity-producing yeast, Candida sp. IR11

“…In previous research, it was demonstrated that the fungus Coriolus versicolor secretes laccase as a mediator in a MFC (Wu et al, 2012). The secreted laccase reduces O 2 to H 2 O and a C. versicolor-inoculated MFC generates seven times higher power density than a non-inoculated MFC (Wu et al, 2012). Electron transfer by microorganisms in MFC systems is performed through the electron transfer chain (ETC) in cells (Hubenova and Mitov, in press;Schaetzle et al, 2008).…”

“…In the case of eukaryotic cells, investigation of electron transfer mechanisms are not well established because they have more complicated cell structures than prokaryotic cells (Hubenova and Mitov, in press). In previous research, it was demonstrated that the fungus Coriolus versicolor secretes laccase as a mediator in a MFC (Wu et al, 2012). The secreted laccase reduces O 2 to H 2 O and a C. versicolor-inoculated MFC generates seven times higher power density than a non-inoculated MFC (Wu et al, 2012).…”

“…and Penicillium sp. were evaluated as biocatalysts in MFCs systems (Morant et al, 2014;Wu et al, 2012). Among eukaryotic cells, yeast cells have several advantages for MFC systems (Mao and Versoerd, 2013;Schaetzle et al, 2008).…”

Celdas de Combustible Microbianas (CCMs): Un Reto para la Remoción de Materia Orgánica y la Generación de Energía Eléctrica

“…En este sentido Lovley (2011) discute sobre los aspectos conocidos hasta el momento cuando se emplean bacterias; sin embargo, también se han empleado microalgas (Mitra y Gordon, 2012) y ya se conoce un primer informe sobre la inoculación del hongo Coriolus versicolor en la cámara catódica que demostró que la producción de la enzima lacasa por el hongo mejoró la eficiencia de reducción de oxígeno a agua y esta CCM produjo más alta densidad de potencia que la CCM control (Wu et al, 2012).…”

Solid phase bio-electrofermentation of food waste to harvest value-added products associated with waste remediation

“…Direct electricity generation from wastewater treatment using bioelectrochemical systems (BES) is advantageous, because thermodynamic conversion step is not necessary (Venkata Mohan et al, 2007Huang and Logan, 2008). BES is a hybrid bioelectrochemical device, which directly transforms energy stored in chemical bonds of substrate to electrical energy via bioelectrochemical reactions mediated by microorganisms as biocatalyst (Rahimnejad et al, 2011;Wu et al, 2012). Microorganisms extract energy required to build biomass (anabolic process) from redox reactions (catabolism) through electron donor/acceptor conditions.…”
