This dissertation presents an investigation of calcium carbonate precipitation via hydrolysis of urea (ureolysis) catalyzed by plant-extracted urease enzyme for soil improvement. In this approach to soil improvement, referred to as enzyme induced carbonate precipitation (EICP), carbonate minerals are precipitated within the soil pores, cementing soil particles together and increasing the dilatancy of the soil. EICP is a bio-inspired solution to improving the properties of cohesionless soil in that no living organisms are engaged in the process, though it uses a biologically-derived material (urease enzyme). Over the past decade, research has commenced on biologically-mediated solutions like microbially induced carbonate precipitation …
