Microbial-Induced Carbonate Precipitation (MICP): Bio-Cement for Sustainable Infrastructure

Abstract Microbial-Induced Carbonate Precipitation (MICP) has emerged as a promising bio-mediated alternative to conventional cementitious materials that contribute substantially to global carbon emissions. The process exploits the metabolic activity of ureolytic microorganisms, particularly Sporosarcina pasteurii, to induce calcium carbonate precipitation within granular matrices. Resultant mineral deposition generates strong interparticle bonding, reduces permeability, and enhances compressive strength under ambient conditions. MICP also promotes autonomous crack sealing, thereby improving structural resilience and durability. This study examines the interaction between microbial activity, physicochemical process variables, and engineering performance. Unlike Portland cement production, which depends on energy-intensive calcination, MICP operates through biologically regulated mineralization pathways with substantially lower embodied energy demand. The technology therefore offers significant potential for sustainable and low-carbon infrastructure development. Several barriers continue to limit field-scale implementation. High bacterial cultivation costs, non-uniform reagent distribution, ammonium accumulation during ureolysis, and uncertain long-term durability under fluctuating environmental stress remain critical concerns. Despite these constraints, advances in microbial biotechnology and geomaterials engineering continue to strengthen the scientific and practical viability of MICP for next-generation sustainable construction systems.
