Cellulase is a key enzyme of industrial interest and plays a crucial role in the hydrolysis of
cellulose a prime component of plant cell walls. Cellulase covers a broad area in the global
market of industrially important enzymes and it is considered as the third largest industrial
enzyme globally. Additionally cellulase contributes about 20% of the total enzyme market
globally because of its massive demand in various industries such as in biofuel production
pulp paper textile food and beverages as well as in detergent industries. Among these the
demand of cellulase may become frequently selected in the commercial production of biofuels in
the future and thus will further increase demand of cellulase in the biofuel industry. Because
biofuel production is still not realized in a cost-effective practical implementation due to
its high cost (the higher cost of biofuels is due to higher production costs of enzymes) there
is a need to introduce these types of approaches which will help to lower the cost of enzyme
production for developing overall economic biofuel production.
