N2 - Bio-mediated geotechnology refers to the technology that utilizes various types of microbial processes to improve the hydro-mechanical behavior of soil and rock, aiming for the prevention and mitigation of geoengineering problems. This paper provides a detailed and comprehensive review of bio-mediated geotechnologies, aiming to enhance understanding in this field. The review encompasses mechanisms, influencing factors, engineering properties, applications, as well as challenges and prospects associated with bio-mediated geotechnologies. Three typical bio-mediated geotechnologies are examined: biomineralization, biofilm, and biogas, with a specific focus on microbially induced calcium carbonate precipitation (MICP). Key factors affecting MICP efficacy, including bacteria species, bacteria concentration, temperature, pH, cementation solution, soil properties, and treatment strategies, are elaborated upon. The paper highlights the significant improvements in mechanical strength, permeability reduction, and erosion resistance achieved through MICP treatment. Furthermore, a wide range of applications for MICP in geotechnical and environmental domains are reviewed, spanning from foundation treatment to geological disaster prevention. Despite its promise, MICP faces challenges such as environmental impact mitigation, uniform distribution, and large-scale application. The paper concludes by discussing future research directions, emphasizing interdisciplinary collaborations and innovative approaches to address these challenges and fully realize the potential of MICP in geotechnical engineering applications.
