Xylan degrading microbe could drive cellulosic biofuels production [Registered]

In cellulosic biofuels production, making effective use of C5 sugars from hemicellulose is a constraint. Hydrolysis and conversion of hemicellulose xylan to biofuels can improve the economics of bioenergy production. Researchers at the University of Illinois have identified a microbe Caldanaerobius polysaccharolyticus, a thermophile that is capable of degrading xylan. Specifically, the bacterium contains all of the proteins and enzymes needed to break down xylan, which is the most common hemicellulose, and then to transport the fragments into the cell and metabolize them. All of the genes are located in a single cluster on the microbe’s genome. “So instead of…
