Scaling up biocement production in the Department of the Air Force
Scaling up biocement production in the Department of the Air Force
Bacterial-based biomineralization is currently under active investigation in academic, industrial, and government labs around the globe. Particularly, Microbially Induced Calcium Carbonate Precipitation (MICP) is a biomineralization strategy the relies on targeted metabolisms to produce CO32- that can complex with exogenously added Ca2+ to produce CaCO3. In commercial applications, the CaCO3 can serve to cement aggregates together to form hardened surfaces and/or industrial building materials. This presentation will describe the investigations and the challenges that we have encountered in the Department of the Air Force as we have developed a strategy for large scale production of a powder-based product for ureolytic MICP. The presentation will highlight work that we have completed internally and with external partners to scale up production of our powder-based material and the quality control testing that we do to validate the efficacy of our product.
