The global urgency for sustainable energy solutions amid climate change and fossil fuel depletion has driven innovation in Microbial Fuel Cells (MFCs). This study investigates the synergistic interactions within a thermophilic microbial consortium (MS9 & MS12) to optimize energy efficiency in MFCs. By varying the inoculum ratios (1:1, 1:2, and 1:3), the research evaluates how microbial population balance impacts bioelectricity production. The MFCs were operated for 24 hours, with voltage measurements recorded every 2 hours. Results revealed that a 1:3 (MS9:MS12) ratio achieved the highest voltage output, peaking at 20 hours before declining, indicating metabolic synergy and efficient substrate utilization. Descriptive analysis highlighted the critical role of cross-feeding mechanisms and functional complementarity between species in enhancing electron transfer. The findings align with modular co-cultivation principles, emphasizing the importance of engineered microbial ratios for stable system performance. This study provides a protocol for designing balanced thermophilic consortia, advancing sustainable bioenergy strategies through optimized microbial interactions.
