Abstract

The invention discloses high-cadmium-adsorption filamentous fungi hair mold XLC as well as a preparation method and an application thereof. The preparation method comprises the following steps of: weighing and adding pot experiment soil sample containing 50mg.Kg<-1> of heavy metal cadmium for heavy metal restoration in sterile water added with glass beads, vibrating on a constant-temperature shaking table, standing, taking supernatant liquid and diluting; coating different dilution factors of diluent on a Martin solid culture medium containing cadmium, and inversely placing the flat plate in a constant-temperature incubator for cultivation; carrying out streaking and purification on microorganisms which grow on the culture medium, carrying out secondary screening and verification, thus obtaining the filamentous fungi hair mold XLC bacterial strain having stable resistance capacity on cadmium after isolation and screening, and storing on a PDA (Potato Dextrose Agar) inclined plane for standby application. The preservation number of the bacterial strain is CCTCC NO: M2012136. The cadmium adsorption capacity of the active thallus of the bacterial strain is higher than that of a dead thallus. The bacterial strain has high-efficiency removal capacity on cadmium in electroplating wastewater treatment and can be used for repairing the cadmium pollution in water and soil in practical application.

Description

technical field

[0001] The invention belongs to the field of water body environment treatment, and specifically relates to a filamentous fungus Mucor with high adsorption of cadmium, and also relates to a preparation method of the filamentous fungus Mucor with high adsorption of cadmium, and also relates to a filamentous fungus with high adsorption of cadmium. Application of fungus Mucor in bioremediation of heavy metal cadmium polluted water and soil. Background technique

[0002] Soil and water are both important components of the natural environment and resources that humans depend on for survival. With the intensification of human activities, more and more heavy metal pollutants have been released through atmospheric deposition, sewage irrigation, solid waste discharge, and pesticides and fertilizers. Applied and other ways into the soil and water (Li Tianjie, 1995). The accumulation of harmful heavy metals to a certain extent will cause toxicity to the ecosystem, and c...
