ABSTRACT

Lignin is the second most abundant heterogeneous polymer after cellulose and a magnificent source of renewable energy. It is a major component of lignocellulosic biomass, a by-product from several industries like pulp and paper in the form of solid waste or effluent. Apart from its utility, it is strenuous to degrade because of its complex structure, which creates a threat to environment and public health. Compared to chemical processing, biotransformation mediated by microorganisms is preferred as it is a clean and efficient technique for lignin transformation. The enzymes secreted by a different group of microorganisms play a major role in degradation. In this article, two main classes of enzymes i.e lignin modifying enzymes and lignin-degrading enzymes and their action have been described.
