Abstract
An alkali-treated bagasse is prepared by softening a bagasse with calcium oxide together with or without sodium hydroxide while preventing the substantial decomposition of cellulose and hemicellulose, a bagasse feed and a fermented bagasse feed prepared from the alkali-treated bagasse, and their preparations and uses as well as bacteria for fermenting the alkali-treated bagasse.

7. A process for preparing an alkali-treated bagasse, which consists essentially of;
-
(a) incorporating calcium oxide in an amount not exceeding 5% of the weight of said bagasse on a dry solid basis into a bagasse together with or without sodium hydroxide under the coexistence of water to subject said bagasse to a condition of not less than pH 10.3; (b) allowing the mixture to stand; and (c) recovering the resultant alkali-treated bagasse having a pH in the range of about 8 to less than 10. - View Dependent Claims (8, 9, 12)
