Purification of Intramineral Peptides from Cuttlebones and In Vitro Activity in CaCO3 Biomineralization

“…Upon increasing the concentration to 50 μg/mL, the rhombohedral crystals were aggregated to form large crystals (Figure b). At high concentrations of SOMs (i.e., 500 and 1000 μg/mL), large numbers of small rhombohedral calcite crystals aggregated to form spherical crystals with more smooth surface morphologies (Figure c,d). − Increasing the concentration of SOMs allows the small calcite crystals to stick together with the help of these intramineral proteins and form large spherical crystal aggregates with rough surfaces. , Since relative sizes of the crystals in Figure a and aggregates in Figure d are the same, it is possible that at high concentration of SOMs, the peptides present in the SOMs facilitate aggregation of crystallites. Such process implies strong interactions between the peptides in SOMs and growing crystal surfaces.…”
