Biohydrogen production from solid phase-microbial fuel cell spent substrate: A preliminary study

Bioelectricity generation using long-term operated biocathode: RFLP based microbial diversity analysis

“…In this case, microorganisms, namely bacteria, will take electrons at the cathode by the reduction of electron acceptors such as nitrate, sulfate, perchlorates and metals [9] , [10] , [11] , [12] . Biodegradable organic matter is, thus, converted into electricity, hydrogen or other value added materials through MFCs [13] , [14] , [15] . In several studies, researchers used human waste [16] , agricultural waste [17] and food waste [18] in MFCs to produce energy or chemicals.…”

Bioenergy from biofuel residues and waste

“…Florio et al. (2019) examine a two‐step process using microbial fuel cells (MFCs) and anaerobic digestion to produce biohydrogen and methane. Using MFC spent substrate instead of fresh, untreated organic substrate from municipal solid waste yielded a 276% increase in biohydrogen and a 66% reduction of methane.…”

SMFC as a tool for the removal of hydrocarbons and metals in the marine environment: a concise research update

“…Bioelectrochemical systems (BESs) represent an emerging technology whose application can range from industrial and municipal effluents treatment to water desalination, from the production of commodity chemicals and energy vectors to CO 2 reuse (Santoro et al 2017 ; Ghangrekar and Chatterjee 2017 ; Kadier et al 2016 ; Avignone-Rossa and Nastro et al 2019 ). BESs have the potential to reduce the environmental impacts of solid, liquid waste and agricultural systems management while contributing to energy saving by means of electric power and/or energy vectors production (Corbella et al 2017 ; Li et al 2018 ; Chandrasekhar et al 2017 ; Florio et al 2019 ; De Vrieze et al 2018 ; Nastro et al 2015 ; Flagiello et al 2021 ). BESs include microbial electrolysis cells (MECs), microbial electrosynthesis cells (MES), microbial desalination cells (MDCs), all requiring an external source of energy, and microbial fuel cells (MFCs) which usually do not require any external energy input.…”
