N-Butanol Production Via Fermentation of Sugar Maple Wood Extract Hydrolysate

摘要

In recent years high crude oil price and increasing concerns over global warming have renewed interest in biotechnological production of butanol, not only as a chemical, but also as an alternative fuel1. The prospect for using fermentations to replace the production of acetone and butanol from chemical processes depends largely on the availability of cheap and abundant raw substrates. As the second most abundant polysacchar- ides in nature2, hemicellulose has the greatest potential as fermentation substrates because (1) it is the least expensive and (2) it is often undesirable by products of certain industries(e.g., paper and pulp) and agricultural process3. In this study, the production of n-butanol via fermentation of sugar maple hemicellulose hydrolysate, using Clostridium Acetobutylicum ATCC824 and Clostridium Beijerinckii ATCC 35702 were investigated.
