Penicillium echinulatum 9A02S1 is a filamentous fungus with a cellulolytic system that may be used in the processes involved in the degradation of lignocellulosic materials for ethanol production. In this study, the 9A02S1 strain of P. echinulatum was grown in submerged cultures with various carbon sources to assess the activities of cellulases and β-glucosidases and their enzymatic activities were assessed utilizing polyacrylamide gel electrophoresis. Cellulose was used as the inducer. Carboxymethyl cellulose proved to be an efficient carbon source for the production of endoglucanase and filter paper activity. Cellobiose, glucose and sorbitol stimulated the production of β-glucosidases. The presence of multimeric forms of the enzymes or their post-translational modifications were assessed.
