Embodiment Construction
[0014] A method for sand-fixing by salt-tolerant bacteria according to the present invention, in the presence of urea and calcium ions, the method uses desert underground salt water to fix the surface sand by mineralization, and the specific operations are carried out according to the following steps:
[0015] a. Bacteria source and culture: The bacteria selected are Bacillus sporosarcinapasteurii, the strain comes from the American Type Culture Collection, with the preservation number ATCC11859, the strain is placed in the nutrient broth medium, and after recovery, transfer to 50ml nutrient broth for culture In the base conical flask, the pH was adjusted to 4-11, and then the conical flask was placed under the conditions of a rotating speed of 130 rpm and a temperature of 30°C for 48 hours to obtain the acclimatized and enriched bacterial liquid;
[0016] b. Preparation of bacterium liquid with inductive solidification effect: the bacterial bacterium liquid obtained in step a ...
