[Comparative study of the growth of Trichoderma reesei and Penicillium occitanie].
During the last years, a great deal of research on the production of energetic substances was directed to the use of cellulosic by-products. A technique of special interest is the production of fermentissible sugars by the enzymatic hydrolysis of cellulose. Mandels and Reese (1960) showed that a fungi strain of Trichoderma reesei is the best performant microorganism in the production of cellulolytic enzymes. Nevertheless, recent investigation indicated that the rate and the yield of conversion of cellulose to glucose of this strain are limited by its poor beta-glucosidase activity. In order to increase the efficiency of the hydrolytic power of the cellulasic complex two approaches can be considered. Beta-glucosidase enrichment of Trichoderma reesei enzymes. The selection and use of strains with a better performance. In our laboratory, we chose the second approach using Penicillium occitanie comparing it to Trichoderma reesei.
