摘　　要：微生物在实际应用中表现出巨大的功能潜力,但游离的微生物生产成本较高、作用效率较低、环境耐受性较差及可回收率较低,而固定化技术可以提高微生物上述性质且已在多个领域得到应用。固定化方法有多种,以吸附为基础的联合固定取得较显著成果,提高载体材料对微生物的吸附量及吸附力具有重要意义,开发高效、耐用、低廉的载体材料是微生物固定化技术得以推广应用的关键。综述了天然生物质材料固定微生物并用于环境治理的应用现状。对基于生物质材料的载体改性优化及菌丝球替代载体的相关研究进行了总结及展望,强调未来通过化学工程与基因工程相结合的策略调控微生物固定化应用效率。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.
