Calcium carbonate represents a large portion of carbon reservoir and is used commercially for a variety of applications. Microbial carbonate precipitation, a by-product of microbial activities, plays an important metal coprecipitation and cementation role in natural systems. This natural process occurring in various geological settings can be mimicked and used for a number of biotechnologies, such as metal remediation, carbon sequestration, enhanced oil recovery, and construction restoration. In this study, different metabolic activities leading to calcium carbonate precipitation, their native environment, and potential applications and challenges are reviewed.
碳酸钙占据了碳库的很大一部分，并且在商业上被广泛应用于各种领域。微生物碳酸盐沉淀是微生物活动的一种副产物，在自然系统中扮演着重要的金属共沉淀和胶结作用。这种在各种地质环境中发生的自然过程可以被模拟，并应用于许多生物技术中，例如金属修复、碳封存、提高石油采收率和建筑修复。在本研究中，我们综述了导致碳酸钙沉淀的不同代谢活动、它们的自然环境以及潜在的应用和挑战。
