Industrial interest in cellulase is high due to its wide
application in various industries such as animal feed
production, starch processing, malting and brewing, grain
alcohol fermentation, extraction of fruit and vegetable
juices, as well as manufacture of pulp, paper and textiles
(Adsul et al., 2007; Kaur et al., 2007). Enzymatic hydrolysis
of cellulosic materials is achieved by a sequence of
reactions with the main components of cellulase complex
enzymes, which include FPase, CMCase and β-
glucosidase. The characteristics of all these three
component of cellulase complex are the main factors that
influence the application of enzyme-based bioconversion
technology. Therefore, research has been directed to
discover new microorganisms that have capability to
produce cellulolytic enzymes with high specific activity
