Abrupt urbanization and industrialization around the world resulted in elevated
environmental pollution and depletion of natural energy resources. An eco-friendly and
economical alternative for energy production is the need of an hour. This can be achieved
by converting the waste material into energy. One such waste is lignocellulosic agricultural
residues, produced in billions of tons every year all around the world, which can be
converted into bioethanol. The main challenge in this bioconversion is the recalcitrant nature
of lignocellulosic material. The removal of cementing material is lignin and to overcome
the potential inhibitors produced during the disintegration of lignin is the challenging
task for biotechnologist. This task can be achieved by a number of different methods
but laccase is the most effective and eco-friendly method that can be used for effective removal
of lignin along with the increase the accessibility of cellulose and bioethanol yield.
