Conversion of cellulosic materials to sugar

摘要: A process for the production of sugar, mainly glucose, by enzymatic degradation cellulosic materials, particularly wastes, which comprises hydrolyzing material in presence cellulase enzyme to produce a sugar solution and recovering from hydrolysis products major proportion used reaction re-use. At least portion required makeup is produced two-stage operation wherein, first stage, output utilized grow cellulase-secreting microorganism, and, second formation induced microorganism-containing culture medium addition an appropriate inducer, such as material. Cellulase precipitated liquid organic solvent material, low molecular weight alkyl ketone or alcohol, precipitate then fed reaction.
