A Bibliometric Analysis of Lysinibacillus spp. as Electrogenic Bacteria in Microbial Fuel Cells

ABSTRACT: Microbial fuel cells (MFCs) harness microorganisms' metabolic processes to convert organic compounds into electricity, offering an eco-friendly energy solution. As the global demand for sustainable energy sources increases, MFCs have emerged as a promising technology for both bioremediation and biomass power generation. However, optimizing microbial performance remains a challenge, particularly in identifying and enhancing the role of electroactive bacteria. Among them, Lysinibacillus sp. has shown potential for efficient electron transfer, yet its contributions to MFC performance remain underexplored. To address this gap, bibliometric analysis provides a systematic approach to mapping research trends, identifying key contributors, and evaluating the evolution of scientific knowledge in this field. This study employs bibliometric analysis via Dimensions AI and VOSviewer to explore research on Lysinibacillus sp. in MFCs. The analysis identified 3029 publications from 2015 to 2024, peaking in 2022 and 2023. Dominant fields include biological sciences and microbiology, with 1210 and 571 publications, respectively. Varjani, Sunita was the most prolific author, and India was the leading contributor with 610 documents and 19,663 citations. Bioresource Technology was the top journal, and Amity University led in co-authorship. Key references are Geyer, R., and Logan, B.E. The analysis provides insights into research trends, significant publications, and future directions for advancing MFC technologies.
