**6. Conclusions**

Cellulases are important enzymes in cellulose degradation that occurs in nature, this degradation involves a system of extracellular multienzymes and have wide application. Molecular biology combined with recombinant DNA technology is a viable tool in enzymatic production with high activity, what makes recombinant fungal cellulases good candidates for industrial applications, including the saccharification of lignocellulosic materials.
