Bibliometric Analysis: Mechanistic Analysis of the Source Microbiota for Bioelectricity Generation in Microbial Fuel Cells

This study presents a bibliometric analysis of research on anodic microbiota in microbial fuel cells (MFCs), focusing on their role in bioelectricity generation. The findings reveal sustained growth in publications from 2000 to 2025, with scientific articles comprising 81.4% of total output, reflecting an experimental approach to optimizing electroactive microbial communities such as Geobacter and Shewanella. Keyword clouds and co-occurrence maps highlight the interdisciplinary nature of the field, linking microbiology, electrochemistry, and environmental applications like bioremediation. Bioresource Technology and Environmental Science & Technology emerge as leading journals in impact, with thematic clusters illustrating the convergence between fundamental and applied research. China, the United States, and Europe dominate scientific output, with key international collaborations led by authors such as Zhang Y and Wang H. Future trends point toward integrating artificial intelligence, synthetic biology, and novel materials (nanomaterials, biopolymers) to enhance MFC efficiency and scalability. Additionally, their potential integration with systems such as constructed wetlands for wastewater treatment and renewable energy generation is emphasized. In conclusion, this analysis underscores the maturity of the field, the significance of global collaboration, and the need to address challenges in scalability and economic sustainability. The findings guide future research toward innovative electrode designs, optimization of microbial consortia, and practical applications, reinforcing MFCs as a promising technology for energy transition and environmental remediation.
