Anaerobic Fermentation of Glucose, Xylose and Hemicellulose Present in Pre- Pulping Extracts of Northern Hardwoods to Carboxylic Acids.

摘要

Wood is composed primarily of cellulose, hemicellulose and lignin. In the paper industry the cellulose fraction is important as the major resource in paper production, whereas the hemi- cellulose and the lignin are usually burned for heat recovery. Recently the hemicellulose has received much attention for the production of different bioproducts. Varying amounts of hemicellulose and associated organic acids can be extracted from wood chips when they are subjected to pre-pulping extraction under different conditions of chemical loading and extraction severity. A major interest for use of the extract this is to convert the hemicellulose into valuable chemicals via fermentation.
