Abstract

|
The aim of this review is to determine the trends of state-of-art of laccase sources, properties, structure and recent application of fungal laccase in various fields. Laccases are biotechnologically important multi copper proteins that have broad substrate specificity towards aromatic and non-aromatic compounds. Fungi are the major laccase producers especially ascomycetes, deuteromycetes and basidiomycetes, and laccases have an average molecular weight between 50 and 130 kDa. Fungal laccases are used in biotechnological applications for preparation of anticancerous and anti-oxidant hormonal drugs, stabilization of food products, and laccase application is also extended to preparation of biosensors, DNA labeling, immunochemical assay, bioorganic compound synthesis etc. The environmental application of laccase is for biodegradation of dyes, phenols and pesticides, and the mechanism of degradation has been briefly explained. Analysis of the biodegraded dye sample by FT-IR and Mass (ESI)-spectrum has been discussed in a detailed manner. Modeling kinetics has been discussed with respect to degradation of wastes in order to understand the factors involved in the degradation process.
