| Sumario: | In the present investigation, we reported a novel green strategy for the biological synthesis of calcium carbonate crystals using water-soluble polysaccharides extracted from the apple and pear. The resultant crystals were characterized by scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, and X-ray powder diffractometry (XRD). The results showed that water-soluble polysaccharides as a soft template were easy to induce calcium carbonate with unusual morphologies (such as straw bundles-like). Based on the time-dependent growth of CaCC3 particles, possible mechanisms were proposed for the formation of straw bundle-like CaCC3 microspheres with secondary structures in the presence of water-soluble polysaccharides. |
