【Abstract】 Laccases are found in fungi and plants. After bacterial laccase was firstly reported in 1993, more and more evidences have proved their distribution in prokaryotes by bioinformatics analysis and experimental data. In this paper, recent advances of research on bacterial laccases are reviewed from the following aspects: bacterial strains, the determination of the enzyme activity, enzymatic characteristics, molecular biology and industrial application. The results show that bacteria can produce a high amount of laccase in a short time due to their fast growth speed. Compared with fungal laccases, there is no glycosylation modification in bacterial laccases, and they have higher thermal stability and enzyme activity in alkaline environments. Therefore, laccases produced by bacteria is of great significance in industrial applications such as environmental protection, food industry, paper bleaching, and so on.更多还原
