摘要
Abstract
Objective]The Saccharomyces cerevisiae with producing low isopentanol was constructed by knocking out geneYDL080c.[Method] The Saccharomyces cerevisiae with producing low isopentanol was constructed byusing Cre-loxP recombination system and yeast electrical trans-formation method to knock out the gene YDL080c encoding pyruvate decarboxylase,in order to cut off the produce of isopentanol in metabolism of Saccharomyces cerevisiae.[ Result] The engineering strain Y1 without YDL080c was successfully constructed.The relative isopentanol content was 0.81 g/L in wine brewed by Y1, which was 28.3% lower than that of the original strain.[Conclusion]Engineering Saccharomyces cerevi-siae without gene YDL080c can effectively reduce the production of isopentanol in brewed wine.关键词
