Laccases (p-diphenol: oxygen oxidoreductase, EC 188.8.131.52) are multi-copper polyphenolic oxidases that oxidize many phenolic and non-phenolic aromatic compounds such as amino or methoxy monophenols, syringaldazine, ABTS and amino or methoxy monophenols. They have been depicted in various species of bacteria, plants and in different genera of fungi. Laccases have been purified by various methods. It involves in di-oxygen to water reduction and 1e- oxidation of phenolic and its allied parts. Laccases are mostly used in different industries like food, paper and pulp, pharmaceutical and textile etc. Both laccases and mediators have been used in different process like delignification of pulp. Laccases from bacterial species are used in dye decolouration and biobleaching processes. This review article describes the whole overview of laccases.
Novelty Statement | This paper reported the updated knowledge about bacterial laccases.
