Bovine serum albumin; sucrose; calcium carbonate; biomineralization; mechanism.

To understand the role of the sucrose/bovine serum albumin system in the biomineralization process, we have tested the influence of different concentration of the sucrose/bovine serum albumin (BSA) on calcium carbonate (CaCO₃) precipitation. The CaCO₃ crystals were characterized by scanning electron microscope (SEM), Fourier transform infrared spectrograph (FT-IR) and powder X-ray diffractometry (XRD). The possible formation mechanism of CaCO₃ in the sucrose/bovine serum albumin system was discussed.
