Microbe-mineral interactions are ubiquitous and can facilitate major biogeochemical
reactions that drive dynamic Earth processes such as rock formation. One example is
microbially induced calcium carbonate precipitation (MICP) in which microbial activity leads
to the formation of calcium carbonate precipitates. A majority of MICP studies have been
conducted at the mesoscale but fundamental questions persist regarding the mechanisms of
cell encapsulation and mineral polymorphism. Here, we are the first to investigate and …
