Microbially-induced calcium carbonate (CaCO3) precipitation (MICP) is a widely explored and promising technology for use in various engineering applications. In this review, CaCO3 precipitation induced via urea hydrolysis (ureolysis) is examined for improving construction materials, cementing porous media, hydraulic control, and remediating environmental concerns. The control of MICP is explored through the manipulation of three factors: (1) the ureolytic activity (of microorganisms), (2) the reaction and transport rates of substrates, and (3) the saturation conditions of carbonate minerals. Many combinations of these factors have been researched to spatially and temporally control precipitation. This review discusses how optimization of MICP is attempted for different engineering applications in an effort to highlight the key research and development questions necessary to move MICP technologies toward commercial scale applications.
微生物诱导碳酸钙沉淀（MICP）是一种广泛探索和有前途的技术，可用于各种工程应用。在这篇综述中，研究了通过尿素水解（脲解）诱导的碳酸钙沉淀来改善建筑材料、胶结多孔介质、水力控制和解决环境问题。通过操纵三个因素来控制 MICP：（1）微生物的脲酶活性，（2）基质的反应和传输速率，以及（3）碳酸盐矿物的饱和度条件。已经研究了这些因素的许多组合，以时空控制沉淀。本文讨论了如何针对不同的工程应用尝试优化 MICP，以突出将 MICP 技术推向商业规模应用所需的关键研究和开发问题。
