Transcriptomes of a xylose-utilizing industrial flocculating Saccharomyces cerevisiae strain cultured in media containing different sugar sources

The molecular basis for glucose and xylose fermentation by industrial Saccharomyces cerevisiae is of interest to promote bioethanol production We used microarrays to investigate the transcriptional difference of a industrial strain cultured in both single sugar media and a mixed sugar medium of glucose and xylose工业酿酒酵母（Saccharomyces cerevisiae）对葡萄糖与木糖的发酵分子机制，对于促进生物乙醇生产具有重要研究价值。本研究利用基因芯片（microarrays），探究了一株工业酿酒酵母菌株分别在单一糖源培养基以及葡萄糖-木糖混合糖源培养基中培养时的转录差异。
