Abstract
PURPOSE: To obtain constituent sugars of wood in high yield, and utilize wood resources efficiently, by breaking the cell tissue of wood by grinding, etc., and saccharizing with cellulase.
CONSTITUTION: Cell structure of wood containing cellulose, hemicellulose and lignin, is broken with a vibration ball mill, etc. The crushed wood is treated with enzyme containing cellulase obtained from bacteria belonging to Aspergillus genus, usually at 30W55°C, substrate concentration of 1W50 wt% and enzyme concentration of 0.1W5 wt%, and the cellulose, hemicellulose and lignin in the wood are selectively saccharified in high efficiency to afford the constituent sugars such as mannose, glucose, etc., in high yield. Wood resources including scrap wood can be efficiently converted to useful sugars, by this process.
