Abstract:

Microorganism has shown great functional potential in practical application, but the defects of free microorganism causing high production cost, low efficiency, poor environmental tolerance and low recovery inhibit its use, while the immobilization technology can improve the above properties of microorganism and has been applied in many fields. Among various methods, the combined immobilization based on adsorption has achieved remarkable results, and it is of great significance to increase the adsorption capacity and adsorption capacity of carrier materials, thus the development of efficient, durable and low-cost carrier materials is the key to the popularization and application of microbial immobilization technology. In this paper, the application of natural biomass materials as the immobilized carrier of microorganisms for environmental treatment is reviewed. The research on the modification and optimization of carriers based on biomass materials and substitution of mycelium pellets are summarized and prospected. The strategy of combining chemical engineering and genetic engineering to strengthen the application efficiency of microbial immobilization is emphasized in the future.

Key words: natural biomass, immobilization carrier, microbes, modification and application
