Acetic acid and glycerol are the major by-product in Saccharomyces cerevisiae ethanol fermentation.In this paper,S.cerevisiae Y01 aldehyde dehydrogenase ALD4 gene was disrupted.ALD4 gene deletion mutants DY01 was obtained.The production of S.cerevisiae ethanol was increased by GPDl silenced via antisense expression vector. The results were described as follows:
1, PCR-based loxP-KanMX-loxP and Cre/loxP system apply to delete the industrial strain S.cerevisiae Y01 aldehyde dehydrogenase ALD4 gene.The pro...
