''Saccharomyces eubayanus'', a type of yeast, is a likely parent of the lager brewing yeast, ''Saccharomyces pastorianus''.〔 〕 Lager is a type of beer created from malted barley and fermented at low temperatures, originally in Bavaria. ''S. eubayanus'' was discovered in Patagonia, possibly being an example of Columbian exchange.〔 〕〔 The South American origins of ''S. eubayanus'' have been subsequently challenged by genomic and phylogenetic evidence suggesting a Tibetan origin. The authors of this study argue that their result also "corresponds better with geography and world trade history."〔 == References == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Saccharomyces eubayanus」の詳細全文を読む スポンサード リンク
