细菌漆酶的研究及应用进展

Progress in Study and Application of Bacterial Laccase

漆酶作为一种绿色环保的多酚氧化酶类,目前被广泛地应用于染料降解、造纸等领域。细菌漆酶与真菌漆酶相比,有更好的热稳定性和更宽的最适pH范围。因此,在工业应用方面更具优势与潜力。综述细菌漆酶的来源、分布、分子结构等基本信息,以及目前细菌漆酶发酵生产水平,并对固定化细菌漆酶进行总结。此外,对细菌漆酶在染料废水、电化学应用及造纸等工业生产方面的应用作简要的介绍。

Laccase is widely used in decolorization of dyes, paper as a green polyphenol oxidases. Bacterial laccase has more advantages and potential in the industrial application due to the high temperature and pH stability compared with fungi laccase. In this article, the origination, distribution, molecular structure and fermentation of bacterial lacease were summarized. And the immobilization of bacterial laecase were also mentioned. Meanwhile, the application of bacterial laecase in dyes wastewater, electrochemistry and paper were briefly introduced.
