Microbial Fuel Cells (MFC) can be fuelled using biomass derived from dead plant material and operate on produced chemicals such as sugars, carbohydrates, polysaccharides cellulose, well being “fed” a regular diet of primary plants or algae. An even closer relationship exist if algae (e.g., prokaryotic microalgae eukaryotic unicellular algae) colonise the open to air cathode chambers MFCs driving photosynthesis, producing high redox gradient due oxygenic phase collective algal cells. The hybrid system is symbiotic; conditions within cathodic chamber favour growth whilst increased production oxygen by algae, more powerful giving higher maximum voltage power photo-microbial fuel cell, which ultimately harvested for range end-user applications. utilise wide materials including detritus, composts, rhizodeposits, root exudates, dying macro- microalgae, via Soil-based Cells, Sediment Plant-based microbial cells, floating artificial islands constructed wetlands.

Abstract Microbial fuel cells (MFCs), hailed as a promising technology, hold the potential to combat various wastewater pollutants while simultaneously converting their chemical energy into electricity through biocatalysts. This study explores applicability of dual compartment MFC (DC-MFC) under varying conditions, targeting removal oxygen demand (COD) from landfill leachate and generation. In this setup, anaerobic sludge treatment plant serves inoculum in anode MFC, with Nafion117 membrane acting separator between units. The cathode compartments are filled distilled water continually aerated for 24 h enhance air supply. assesses MFC’s performance across different COD concentrations, focusing on removal, power generation, Coulombic efficiency. findings reveal that efficiency is notably enhanced at higher concentrations organic matter. Specifically, concentration 3325.0 mg L −1 , exhibited highest (89%) maximum density (339.41 mWm −2 ), accompanied by 25.5%. However, initial substrate increased 3825 decreased 72%, 13.56% 262.34 .

Abstract Microbial fuel cell (MFC) technology has received increased interest as a suitable approach for treating wastewater while producing electricity. However, there remains lack of studies investigating the impact inoculum type and hydraulic retention time (HRT) on efficiency MFCs in industrial saline wastewater. The effect three different inocula (activated sludge from fish-canning industry two domestic treatment plants, WWTPs) electrochemical physicochemical parameters anodic microbiome two-chambered continuous-flow MFC was studied. For each inoculum, HRTs were tested (1 day, 3 days, 6 days). fish canning significantly voltage production (with maximum value 802 mV), power density 78 mW m −2 ), coulombic 19.3%), organic removal rate (ORR) compared to WWTPs. This linked greater absolute relative abundances electroactive microorganisms (e.g., Geobacter , Desulfovibrio Rhodobacter ) predicted electron transfer genes anode likely due better adaption salinity conditions.
