A newly bioengineered yeast effectively utilizes C5 sugars from cellulosic feedstock [Registered]

Collaborative research by scientists at the University of Illinois, the Lawrence Berkeley National Laboratory, the University of California and the energy company BP have bioengineered yeast (Saccharomyces cerevisiae) strain that can simultaneously consume C6 and C5 sugar from plants to produce ethanol. The sugars are glucose, a six-carbon sugar that is relatively easy to ferment; and xylose, a five-carbon sugar that has been much more difficult to utilize in ethanol production. The new strain, made by combining, optimizing and adding to earlier advances, reduces or eliminates several major inefficiencies associated with current biofuel production methods. The findings are reported in…
