Microbially induced calcium carbonate precipitation in different substrates

以石灰石形式存在的碳酸盐是地球上重要的碳储存库。它们被记录在几种自然地质构造中，如珊瑚、叠层石、海滩岩石。微生物在自然和人工环境中不同基质上的微生物诱导碳酸钙沉淀（MICP）反应过程中，在碳酸盐的形成和溶解中起着重要作用。由于在分子水平上对反应动力学的理解不足，我们对MICP的了解很有限。该项目将开发新的方法，以实现和推进MICP过程的知识，对理解自然地质构造以及扩大当前工程应用的范围具有深远的影响。

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.
