These tests confirm the feasibility of using plant-derived urease to induce carbonate cementation in sand and provide valuable insight into the factors that must be …
Earth materials have been stabilised by exploiting the urease enzyme that is present in soybeans to catalyse hydrolysis of urea inside the pore water which leads to …

The cost of urease enzyme production and complex extraction procedure are widely considered as a major barrier for the use of bio-cementation via enzyme …
Enzymatically induced carbonate precipitation (EICP) is widely studied as a promising technique for soil stabilization and cementation. The solidification …
The use of plant-derived urease enzyme to induce calcium carbonate (CaCO 3) cementation has been demonstrated through laboratory column tests.
