Coffee pulp, which is waste material from coffee production line, has many poor natural degradeble property. Cellulase aillus nigernd pectinase, which were bio synthesized by the fugus races of Trichoderma viride and Asperg, can improve the disintergration process of coffee pulp. In this study, the conditions affecting the production of these enzymes were studied.. The optimum conditions for producing Pectinase enzyme of Aspergillus niger include: 2 days, 62% of humidity, 8% of culture. The optimum conditions for the production of Cellulase enzyme of Trichoderma viride are lasting for 4 days, 58% of humidity, 8% of culture. By carrying out real experiments we found that coffee pulp was disintergrated in the duration of 14 days, 60% of humidity, 8% of culture.
