Improper disposal practices have caused environmental disruptions, possessing by heavy metal ions and radioactive elements in water soil, where the innovative sustainable remediation strategies are significantly imperative last few decades. Microbially induced carbonate precipitation (MICP) has emerged as a pioneering technology for remediating contaminated soil water. Generally, MICP employs urease-producing microorganisms to decompose urea (NH2CONH2) into ammonium (NH4+and carbon dioxide (CO2), thereby increasing pH levels inducing (CO32−), effectively removing remove contaminants. Nonetheless, intricate mechanism underlying mineralization poses significant challenge, constraining its application contaminants engineering, particularly context of prolonged leaching over time efficacy adverse conditions. This review provides comprehensive idea recent development examining metabolic pathways, mineral mechanisms, factors well providing future perspectives commercial utilization. The use ureolytic bacteria demonstrates cost-efficiency, compatibility, successful pollutant abatement tradition bioremediation techniques, bio-synthesis nanoparticles. limitations such large-scale application, elevated Ca2+levels groundwater, gradual contaminant release need be overcome. possible research directions technology, emphasizing potential conventional remediation, CO2 sequestration, bio-material synthesis, role reducing impact long-term economic benefits.
