Abstract

Abstract

Several varieties of bacteria were isolated and screened from the vicinity of the Salt Lake. The X-NM1 with the strongest capability to induce carbonate deposition was finally selected. It was identified as Staphylococcus epidermidis by 16S rDNA analysis. The induced calcium carbonate deposition was 16.8 g/L, the urease activity was 3.353 mM/min, and the mineralization product was spherical calcite crystals. The X-NM1 was further tested by sand cementation, considering the effect of grouting cycles on sand column solidification. The results showed that with the increase of grouting cycles, the permeability coefficient and porosity of sand columns decreased, while the dry density, pore filling ratio, uniaxial compressive strength and calcium carbonate content increased gradually. After three cycles of grouting, the appearance structure of sand columns was intact, the dry density, the permeability coefficient, the porosity, the pore filling ratio, the uniaxial compressive strength, and the CaCO₃ content was 1.99 g/cm³, 1.51×10^-3 cm/s, 26.35%, 15.42%, 2.52 MPa, and 24.5% respectively. The results showed that X-NM1 was of excellent capability to induce calcium carbonate deposition.
