Abstract

Urease is an enzyme that can catalyzes the hydrolysis of urea. With this reaction, carbonates can be produced. Because of the catalysis, the reaction is quite fast. The products can be used as binders for soil particles, coating materials on solids, sealing agents for cracks and fissures of rock and concrete. To apply this technique for engineering purposes, the grain growth of carbonate products was examined using the ureolytic microbes isolated from the soil. The type and growth rate of the products depended on the type of mediums, and the type and concentration of the metals. Amorphous carbonates were produced using Mg²⁺ and Ca²⁺, which may be better binders than crystalline carbonates.
