A Study on the Character,Feeding Effects and Carrier of Cellulase from Sn-9106

Li Shurong;Chen Zujie (Department of Basic Science, Shenyang Agricultural University)  
This paper is about the character of the solid cellulase from Trichoderma virid Sn-9106 at solid medium fermentation, such as temperature, pH, proteinase-resistence and so on. It is complex enzymes and contains cellulase, semicellulase, pectinase, amylase, proteinase and so on. It is stable at high temperature and 50% activity is remained at 70℃. It has better stability at 40℃, when proteinase and trrpsin are added. the activity of cellulase can remained 81.6% and 77.3% after half an hour. When the amount of this enzyme is 0.2% in the feed, good effect can be obtained. The increased weight is 577g daily gain, the ratio between feed and meat is 2.04. We had studied on the carrier of enzyme too. We deter mined in the adsorption and recovery between the carrier and enzgma. C is the best carrier, it is economic and can be obtained easy.
