Microbially induced carbonate precipitation (MICP) is a cost-effective and environmentally friendly technology to improve saline soil. It aims to use urease generated by bacteria to catalyze urea hydrolysis and produce carbonate, which combines with calcium ion in the cementation solution to form calcium carbonate precipitates and calcite crystal.
