Abstract: Laccase is a kind of oxidases, which is easily obtained and featured with excellent characteristics. More and more attentions have being paid on laccase because of its widespread applications in the field of environmental pollution control. To immobilize the freestate laccase to improve its catalytic efficiency and reuse rate, the selection of carriers is crucial for the immobilization process. Easily obtained and appropriate carriers can simplify the immobilization process, being conducive to the industrialized production and application of immobilized laccase, while inappropriate carriers could directly impact the use efficiency of immobilized laccase. In recent years, with the rapid development of the researches in materials, environment, and other related areas, growing numbers of new and high quality materials have been made into the carriers of immobilized laccase. To a certain extent, these newly developed carriers can enhance the utilization rate of laccase. In addition, some already applied carries after improvement are reused for preparing the immobilized laccase, and make the functions of laccase somewhat improved. This paper introduces several newly developed materials used as the carriers for laccase immobilization, summarizes the functions of laccase after immobilization, defines the optimal conditions for laccase immobilization, enumerates the advantages and disadvantages of various carriers, and analyzes the development trend of the carriers for laccase immobilization.
