AI Technical Summary

Technical Problem

In existing technologies, it is difficult to leach calcium and magnesium ions from natural silicate minerals, resulting in a slow CO2 reaction rate for mineral sequestration. Traditional physicochemical activation methods have drawbacks such as high pollution, high cost, and high energy consumption.

Method used

Bioleaching was performed using *Talaromyces pseudofuniculosus* hzt-3', which significantly enhanced the leaching of calcium and magnesium ions through its metabolites and biophysical effects. This strain was then used to bioactivate minerals such as anorthite, serpentine, and wollastonite.

Benefits of technology

It significantly improves the leaching rate of calcium and magnesium ions, solves the problem of slow CO2 reaction rate in mineral sequestration, and achieves high-efficiency leaching with low energy consumption and environmental friendliness.

Abstract

The invention relates to talaromyces pseudomonas hzt-3'as well as a preparation method and application of the talaromyces pseudomonas hzt-3 ', and belongs to the technical field of application of microorganisms. The strain is preserved in the China Center for Type Culture Collection, the preservation number of the strain is CCTCC NO: M 20251797, and the strain is classified and named as (Talaromyces pseudomonas hzt-3 '). The method comprises the following steps: collecting moss and vegetation soil samples from basalt, diabase and dolomite; diluting bacterial colonies in the sample, and separating and purifying the bacterial strains by using a Czapek culture medium; anorthite and serpentine are used as inorganic salt sources for strain screening, and strains which grow stably and have a good leaching effect on calcium magnesium silicate minerals are obtained; the strain is applied to efficient leaching of anorthite, serpentine and wollastonite, and compared with a sterile control group, the effect of improving the leaching rate of calcium and magnesium ions is remarkable. The method solves the problem that the reaction rate of mineral sequestration carbon dioxide is slow due to the fact that ions in natural silicate minerals are difficult to leach, and has great significance.
