Laccase belongs to the blue multi-copper oxidases, which are widely distributed in fungi and higher plants. Lignin degradation by several white-rot fungi, such as Phanerochaete chrysosporium, Pleurotus ostreatus, Coriolus versicolor, Cyathus stercoreus, and Ceriporiopsis subvermispora, have been studied. Laccase enzymes have attracted attention due to its wide use in textile, pulp and paper, and food industry. Recently, it is being used in developing biosensors for detection and removal of toxic pollutants, designing of biofuel cells and medical diagnostics tool. Laccase is also being used as a bioremediation agent as they have been found potent enough in cleaning up herbicides pesticides and certain explosives in soil. Because of having the ability to oxidize phenolic, non-phenolic lignin-related compounds and highly fractious environmental pollutants, laccases have drawn the attention of researchers in the last few decades. Commercially, laccases have been used to determine the difference between codeine and morphine, produce ethanol and are also being employed in de-lignify woody tissues. To sustain this trend widespread availability of laccase and efficient production systems have to be developed. The current review discuss major advances in application of fungal laccase in white biotechnology. It delineate the laccase production and various cultivation techniques that have been developed to efficiently produce laccase at the industrial scale. The role of laccase in different food industries, and significant recent advances in the use of laccases are discussed in this review.
