Title:
DOUBLE-CORE-SHELL LOADED MICROBIAL MATERIAL AS WELL AS PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/246131
Kind Code:
A1
Abstract:
The present invention provides a double-core-shell loaded microbial material as well as a preparation method therefor and the use thereof. The double-core-shell loaded microbial material is used for mineralizing heavy metals in polluted water. The preparation method for the double-core-shell loaded microbial material comprises the following steps: first, embedding a microbial liquid in an agar solution to obtain an agar-loaded microbial inner shell; then putting the agar-loaded microbial inner shell into a calcium chloride solution, so that the surface of the agar-loaded microbial inner shell is covered with a calcium chloride layer; and finally, embedding the agar-loaded microbial inner shell covered with the calcium chloride layer into a sodium alginate solution mixed with urea, so as to obtain the double-core-shell loaded microbial material. The double-core-shell loaded microbial material of the present invention is used for remedying heavy metal pollution, effectively solving the problem that urease-producing microorganisms cannot tolerate high-concentration heavy metals. The urea and microorganism can be separately embedded at the same time, thus solving the problems of provision of an external urea source and premature reaction. The present invention has wide industrial prospects and market value.
