[0002] Application number: 201410682558.2, publication date: 2015-04-22 Chinese patent, discloses a heavy metal polluted soil treatment agent using Bacillus thuringiensis and Candida tropicalis as active ingredients, using Bacillus thuringiensis and Candida tropicalis as active ingredients The heavy metal polluted soil treatment agent with active ingredients, the bioremediation agent of this invention can absorb a certain proportion of heavy metals, and can remain in the soil for a period of time, but Candida tropicalis belongs to anaerobic fungus, and cannot survive for a long time in dry and ventilated soil. Survival, on the other hand, effective strains have not been domesticated to heavy metals, have poor tolerance to corresponding heavy metals, and the enrichment effect is not good, and because each microorganism has its own limitations, its effect on soil treatment is neither Long-term, not comprehensive

Abstract

The invention discloses a microbial product for treating heavy metal polluted saline-alkali soil. The microbial product comprises a culture medium and a target microorganism, wherein the culture medium contains a nutrition medium and nutrition liquid, and the formula of the nutrition liquid is as follows: each 1L of water contains 10g-20g of agar, 0.2g-0.7g of KH2PO4, 2.5g-3.0g of (NH4)2SO4, 0.5g-1.5g of CaSO4, 1.5g-2.5g of MgSO4.7H2O, 3.0g-4.0g of lactic acid, 0.5g-1.5g of yeast powder, 0.05g-0.15g of ascorbic acid, 0.05g-0.15g of mercaptoacetic acid and 0.2g-0.7g of FeSO4.7H2O; and the target microorganism contains pseudochrobactrum asaccharolyticum, rhodobacter sphaeroides, micrococcus flavus PS5 and white-rot fungi. Lead and zinc ions are enriched and passivated in cells by biologicalmetabolism of microorganisms, protein organisms can be produced and can be combined with adsorbed metal ions, so that the degradation efficiency is improved; and the microbial product has good environmental adaptive capacities such as temperature and pH, and a relatively good remediation effect is achieved.
