Carbonates in the form of limestone represent an important reservoir of carbon on earth. They are recorded in several natural geological formations as corals, stromatolites, beach rocks. Microbes play an important role in the formation as well as dissolution of carbonates during microbially induced calcium carbonate precipitation (MICP) reactions on different substrates in natural and built environments. Much of our knowledge on MICP is limited due to poor understanding of the reaction kinetics at a molecular level. This project will develop new methods to enable and advance the knowledge of MICP process with profound implications for understanding natural geological formations as well as widen the scope of current engineering applications.

石灰石形式的碳酸盐代表了地球上碳的重要储层。它们以几种自然地质地层记录为珊瑚，基质石，海滩岩石。微生物在自然和建筑环境中不同底物上的微生物诱导钙沉淀（MICP）反应过程中在形成和溶解中起重要作用。由于对分子水平上的反应动力学的了解不足，我们对MICP的许多知识受到限制。该项目将开发新的方法，以实现和推进MICP过程的知识，对理解自然地质形成以及扩大当前工程应用的范围有深远的影响。
