PMID: 22214220
Biotechnol Biofuels. 2012 Jan 04;5(1):2. doi: 10.1186/1754-6834-5-2.

BACKGROUND: The model bacterium Clostridium cellulolyticum efficiently degrades crystalline cellulose and hemicellulose, using cellulosomes to degrade lignocellulosic biomass. Although it imports and ferments both pentose and hexose sugars to produce a mixture of ethanol, acetate, lactate, H2 and CO2,...
