Extensive attention is being paid to microbial-induced degradation of aromatic organic compounds and mineralization of zinc ions, as a new green and environmental method, in that it has low cost, simple operation and rapid effects. In this research, toluene was decomposed and the concentration of carbonate ions prepared increased accordingly under the action of micro-organisms; meanwhile, carbonate ions mineralized zinc ions into carbonate precipitations. The compositional and morphological properties of carbonate precipitations were studied by means of X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR) Spectroscopy and Thermogravimetric Analysis (TGA). The characterization data obtained showed that carbonate precipitations and basic zinc carbonate were successfully synthesized using microbial method in this process. Basic zinc carbonate was shown to be nanometer-grade in size and sphere-like in shape. Furthermore, the phase composition, functional groups and surface morphology of samples obtained by the microbial method were mainly similar to the chemical method. This work provided a new method for processing zinc ions based on the degradation of toluene.

Key words: Microbial-induced, degradation, mineralization, basic zinc carbonate, nanoparticles, toluene.
