Nano Scale Investigations of Calcium Biominerals Formed by Bacteria

Some bacteria are able to produce calcium carbonate, a mineral that can be used a biological cement. This biocement can be used for many environmental purposes such as keeping underground stored CO2 in its place and preventing it from escaping back out to the atmosphere, and even trapping heavy metals from contaminated groundwater. To see how these bacteria produce the biocement, we need to study them at a scale where we can see them i.e., the microscale. We use very powerful microscopes to watch single bacteria make the biocement and then analyze the biocement for its stability.
