Utilizing different food cultures for wastewater treatment and enhanced power generation in microbial fuel cells
This study investigates the impact of reactor architecture and biocompatibility of anode material on wastewater treatment and power generation in single-chamber (SC) and dual-chamber (DC) microbial fuel cells (MFCs) by utilizing different bacterial food cultures. Comparison between graphite-coated Cu (composite) and 304L stainless steel (SS) anodes is presented under optimized pH (7.13) and temperature (34 °C). Food cultures, especially buttermilk with an acetic acid substrate, significantly enhanced power density (PD), achieving 2.17 W/m2 using composite anode and 1.67 W/m2 using SS in SCMFCs. Mixed food cultures raised performance by ∼50 % achieving 3.31 W/m2 and 2.97 W/m2 using composite and SS anodes respectively. High chemical oxygen demand (COD) removal rates (>68 %) confirm effective wastewater treatment. These findings suggest that macroporous composite anodes can improve microbial compatibility and power output in MFCs, with optimal performance observed at neutral pH and ambient temperatures.
期刊介绍：
Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials.
The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy.
Key areas covered by the journal:
• Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation.
• Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal.
• Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes
• Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation
• Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
