| Popis: | Two types of substrates, the algal-bacterial type (rich in cellulose I α ) cellulose and the cotton-ramie type (dominant in cellulose I β ) cellulose, were degraded comparatively by Trichoderma viride cellulase. The algal-bacterial type cellulose microfibril was more susceptible than the cotton-ramie type. The residual cellulose microfibrils were observed by TEM and analyzed by FTIR and electron diffraction. It becomes clear that the residual cellulose of the algal-bacterial type cellulose was getting rich in the cellulose I β with the lapse time of cellulase treatment. These results indicate that the cellulose I α in the microfibril of the algal-bacterial type cellulose is hydrolyzed preferentially by the cellulase. |
