Sažetak
Catalytic decomposition of urea by urease in aqueous calcium chloride solutions was used to rapidly prepare calcium carbonate polymorphs at room temperature. The nature of the resulting particles depended on the concentration of the enzyme and, in strong manner, on the agitation of the reacting solution. In undisturbed system an amorphous precipitate is formed first, which readly crystallized to vaterite and on aging changed to calcite. Under the influence of magnetic stirring, amorphous phase could be not observed ; instead smaller particles were initially obtained, which aggregated to vaterite and calcite. It seems that non-specific interactions between crystal surface and enzyme macromolecules are important in the development of calcite faces, as such, they exert significant influence on calcite morphology.
