摘要:
聚氨基甲酸酯(PU)因其具有高强度、抗撕裂、耐磨损等诸多优势,广泛应用于各个领域,但是聚氨酯材料不易降解,给生态环境安全造成很大危害。为了解决这一问题,使用生物方法降解聚氨酯成为当今的研究热点。本文简要概述了聚氨酯的现状、生物降解机理和研究进展。并结合近年来开展的聚氨酯生物降解实例,重点阐述了细菌和真菌降解聚氨酯的机理及进展情况。研究发现,真菌生物降解聚氨酯主要是通过分泌酶进行作用的,真菌附着在聚氨酯材料的表面,通过生物体的繁殖和菌丝的生长破坏聚氨酯材料的结构,同时分泌水解酶、尿素酶、蛋白酶等进一步作用,共同完成聚氨酯的生物降解;而细菌生物降解聚氨酯时,自身先产生一种水溶性胞内酶连接细菌的细胞膜和聚氨酯材料,然后分泌胞外酶破坏聚氨酯底物,将聚氨酯材料分解为小分子物质,而降解生成的小分子则可被细菌生物体直接代谢,最终完成聚氨酯的降解。最后探讨了聚氨酯生物降解的现状和存在的问题,并对聚氨酯生物降解的发展趋势进行了展望,指出未来相关研究应依据聚氨酯的种类、特点来筛选针对性的降解菌株,并开展生物降解作用机理研究,从而为聚氨酯生物降解工艺技术的研发提供理论支撑。(表1 图4 参68)
Abstract:
Polyurethane (PU) is widely used in various fields of modern life due to its advantages of high strength, versatility and resistance. However, PU waste disposal is slowly degraded and usually results in serious environmental problems, such as contaminated soil ecology and water quality health. In order to solve this problem, biodegradation of polyurethane has become a hot research topic nowadays. In this paper, the current status, biodegradation mechanism and research progress of polyurethane are briefly summarized. The degradation mechanism of polyurethane by bacteria and fungi and research progress are emphasized by descripting the biological degradation examples of polyurethane in recent years . It is found that fungal biodegradation of polyurethane mainly through the role of secretase. Fungi usually attach to the surface of polyurethane material and will destroy its structure through the reproduction of organisms and the growth of mycelium ; meanwhile fungi is able to secret hydrolase, urease, and protease, and further contributing to the biodegradation of polyurethane . When degrading polyurethane, bacteria firstly produce a water-soluble extracellular enzyme which can connect bacterial cell membrane and polyurethane material, and then secrete another extracellular enzyme to destroy the polyurethane substrate and decompose the polyurethane material into small molecule material which can be directly metabolized by bacterial organisms and eventually complete the degradation of polyurethane. Finally, the status and existing problems involved in the biodegradation of polyurethane were discussed. The development trend of polyurethane biodegradation was also prospected. Future research should be focused on the isolate of specific degrading strains according to the types and characteristics of polyurethanes and the study on biodegradation mechanism, and thus providing a theoretical support for the research and development of polyurethane biodegradation process technology.
