Synthesis of bioactive material by sol–gel process utilizing polymorphic calcium carbonate precipitate and their direct and indirect in-vitro cytotoxicity analysis

To mitigate the rising level of CO2, biological method of CO2 sequestration is one of the effective methods. Chemolithotrophic microbes are able to fix atmospheric CO2 and precipitated polymorphic minerals like calcite, vaterite and aragonite. Based on this, bioactive glass was synthesized by sol–gel process using polymorphic calcium carbonate mineral precipitated by chemolithotrophic Serratia sp. ISTD04. Characterization of bioactive material...
