Cold-Resistant Yeast Discovered in South American Pottery
Tuesday, September 19, 2017
TEMUCO, CHILE—According to a report from NBC News, traces of yeast have been detected on 1,000-year-old pottery discovered near the Chile-Argentina border. The yeast, called Saccharomyces eubayanus, is thought to have been an ancestor of the yeast currently used to brew lager. Researchers have been looking for the origin of this unusual fungus, which thrives in cold temperatures and has been found growing wild in Patagonia and Tibet. Saccharomyces eubayanus has not been found growing wild in Europe, however. “Our findings confirm the historical presence of the yeast in this region and now we have confirmation of its use,” explained archaeologist Alberto Perez of Universidad Catolica de Temuco in Chile. Scholars now want to know whether Saccharomyces eubayanus traveled from South America to Bavaria, where lager was first brewed in the 1400s. To watch a short film on the work, click here.
