New yeast boosts xylose-to-ethanol efficiencies

In Brazil, researchers from the University of Sao Paolo have successfully developed a new fermentation process with 63% efficiency for producing ethanol from xylose using the yeast Pichia stipitis.

Pichia stipitis NRRL Y-7124 was able to grow and produce ethanol from xylose in a stirred tank bioreactor under different aeration and agitation conditions.
