AI Technical Summary

Technical Problem

Existing microbial agents are not very effective at decomposing phosphorus in mine soils, which limits vegetation growth and makes it difficult to utilize water from high-salt mines, thus hindering ecological restoration.

Method used

Microbial agents were obtained by culturing and purifying Acinetobacter sp. xwp1 and applied to high-salt mine water. They can efficiently solubilize phosphorus in high-salt and alkaline environments, tolerate heavy metals, and are used for contaminated site remediation and agricultural applications.

Benefits of technology

Acinetobacter xwp1 exhibits highly efficient phosphorus solubilization in high saline-alkali environments, significantly enhancing vegetation growth, improving soil structure, adapting to complex ecological environments, and promoting vegetation restoration and soil remediation.

Abstract

The application discloses acinetobacter and a preparation, culture method and application thereof, belongs to the technical field of microorganisms, and solves the problem that the effect of existing microorganisms on decomposition of phosphorus in mine soil is not good. The application discloses acinetobacter and a preparation, culture method and application thereof, belongs to the technical field of microorganisms, and solves the problem that the effect of existing microorganisms on decomposition of phosphorus in mine soil is not good. Acinetobacter sp .) xwp1, which is preserved in the China General Microbiological Culture Collection Center, located at No. 1, Xibei Road, Beichen, Beijing, China Institute of Microbiology, and has a preservation date of November 26, 2024, and a preservation number of CGMCC No. 32804. The acinetobacter provided by the application has excellent phosphorus decomposition capacity, can convert mineral phosphorus in soil which is difficult for plants to utilize into a form that can be absorbed and utilized by plants, has good tolerance and modification capacity for high salt concentration and high alkaline environment, can tolerate heavy metal hexavalent chromium, and has certain tolerance capacity for cadmium and arsenic, and has wide application in site remediation and agriculture.
