However, the main cellulose utilizing species are the aerobic and anaerobic hemophilic bacteria, filamentous fungi, basidiomycetes, thermophilic bacteria and actinomycetes (Wright, 2003). At the first step, the microorganisms responsible for cellulose decomposition bring about an enzymatic hydrolysis of the complex polymer, that is, the enzymes system which involves a group of different enzymes, is collectively known as cellulase
