Delignified cellulosic material has shown a significant promotional effect on the alcoholic fermentation as yeast\r\nimmobilization support. However, its potential for further biotechnological development is unexploited. This study reports\r\nthe characterization of this tubular/porous cellulosic material, which was done by SEM, porosimetry and X-ray powder\r\ndiffractometry. The results showed that the structure of nano-tubular cellulose (NC) justifies its suitability for use in ââ?¬Ë?ââ?¬Ë?cold\r\npasteurizationââ?¬â?¢Ã¢â?¬â?¢ processes and its promoting activity in bioprocessing (fermentation). The last was explained by a glucose\r\npump theory. Also, it was demonstrated that crystallization of viscous invert sugar solutions during freeze drying could not\r\nbe otherwise achieved unless NC was present. This effect as well as the feasibility of extremely low temperature\r\nfermentation are due to reduction of the activation energy, and have facilitated the development of technologies such as\r\nwine fermentations at home scale (in a domestic refrigerator). Moreover, NC may lead to new perspectives in research such\r\nas the development of new composites, templates for cylindrical nano-particles, etc.
