Sporosarcina pasteurii is a ureolytic bacterium that breaks down urea into carbonate and ammonium. The carbonate combines with calcium to form calcium carbonate, creating a crystal lattice that anchors surrounding particles together to produce biocement. This is a convenient protocol for using 3D-printed molds to create biocement bricks suitable for compression testing.
