New way to make yeast hybrids may inspire new brews, biofuels

Orange-colored galls, such as these pictured in 2010, from the beech tree forests of Patagonia have been found to harbor the yeast that makes lager beer possible. Five hundred years ago, in the age of sail and when the trans-Atlantic trade was just beginning, the yeast somehow made its way from Patagonia to the caves and monastery cellars of Bavaria where the first lager beers were fermented. University of Wisconsin-Madison Genetics Professor Chris Todd Hittinger and colleagues have discovered a quick and efficient way to fuse different strains of yeast to make hybrids similar to the lager beer hybrid, an organism that underpins a $250 billion a year industry worldwide.About 500 years ago, the accidental natural hybridization of Saccharomyces cerevisiae, the yeast responsible for things like ale, wine and bread, and a distant yeast cousin gave rise to lager...
