<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing cellulose nanofibers that are excellent in the efficiency of enzyme reaction and allow easy adjustments of an aspect ratio and crystallinity. <P>SOLUTION: The method of manufacturing cellulose nanofibers includes an embrittlement process S1 for crushing a biomass into cellulose microfibrils and a thermal decomposition process S2 for thermally decomposing the cellulose microfibrils using a heat-resistant cellulase. The heating temperature of the thermal decomposition process S2 is higher than 50°C, and the aspect ratio and the crystallinity can be adjusted by adjusting the heating temperature, heating time or enzyme concentration. <P>COPYRIGHT: (C)2013,JPO&INPIT |
