Abstract :
In this paper, The strontium carbonate precipitate was induced with the role of the enzymes according to the bacillus pasteurii reproduction in different concentrations of Si2+. The morphology and structure of strontium carbonate were characterized by X-ray Diffraction (XRD), Energy Dispersive Spectroscopy (EDS) and Scanning Electronic Microscope (SEM). The results showed that the induced strontium carbonate precipitation was mainly orthorhombic, it´s morphology was irregular aggregated bodies and rhombus blocks. Bacterial played an important role in the strontium carbonat crystal nucleation, growth and accumulation process.
