[Objective] This study systematically reviews the research trends in microbially induced calcium carbonate precipitation (MICP) over the past 25 years. Through bibliometric analysis, we aim to elucidate the developmental trajectory, research hotspots, and academic impact distribution of MICP, offering data-driven insights for researchers and proposing strategic priorities for future studies. [Methods] A comprehensive dataset of 1 947 publications was extracted from the Web of Science Core Collection (1999-2024). Bibliometric analysis and CiteSpace visualization tools were employed to quantify publication volume, authorship patterns, country/institutional contributions, and keywords dynamics. Time-series analysis and network mapping were integrated to decode the evolutionary pathways and interdisciplinary frontiers of the field. [Results] Annual MICP publications exhibit sustained growth, with China emerging as the dominant contributor, accounting for 47.71% of global output. Leading institutions such as Nanyang Technological University, Chinese Academy of Sciences, Southeast University, and Chongqing University demonstrate strong academic influence through high publication output and citation frequency. The research hotspots are primarily concentrated in soil improvement, self-healing concrete, and bioremediation. Keywords clustering analysis reveals emerging interdisciplinary frontiers at the intersection of environmental geotechnics and biomaterials applications. [Conclusion] MICP research has entered a phase of rapid multidisciplinary integration, with China leading global advancements. Future efforts should prioritize fundamental studies on bio-mineral interaction mechanisms, accelerate MICP applications in environmental remediation and smart materials, and develop green, sustainable processes to enhance its role in carbon neutrality and ecological engineering.
