SEM & EDS analysis of calcite formations in hydrogels

1 Jul , 2019  

Hydrogels can be used as soil analogues to study bacteria growth and MICP in-situ in a more confined and easily accessible environment.

In this study of microbial induced calcium carbonate crystal growth in agarose hydrogels, Beate has been investigating the influence of variation in the cementation media on micro-scale calcite growth and distribution. EDS X-ray spectra of the crystals confirmed the presence of carbon, oxygen and calcium, the elements that make up CaCO3 which verifies that the formed crystals are calcite.
