    • Methods for enhanced yeast fermentation of plant material through the genetic modification of non-respiring yeast are provided including the introduction of a dominant mitochondrial ATP synthase gene mutation into a non-respiring yeast that entirely lacks mitochondrial DNA and transgenic yeast for the enhanced yeast fermentation of plant material lacking mitochondrial DNA while having a dominant mitochondrial ATP synthase gene mutation in the nuclear genome. Methods further include the introduction of a mitochondrial genome into a non-respiring yeast lacking the COX1, COX2, COX3, or COB gene as well as transgenic yeast having a mitochondrial genome lacking the COX1, COX2, COX3, or COB gene. Additional methods include the creation of a disrupted copy of the CATS nuclear gene in a non- respiring yeast as well as transgenic yeast having a disrupted copy of the CATS nuclear gene are also disclosed.
    • 提供通过非呼吸酵母的遗传修饰增强植物材料酵母发酵的方法,包括将显着的线粒体ATP合酶基因突变引入到完全缺乏线粒体DNA的非呼吸酵母中,并且用于增强酵母发酵的转基因酵母 植物材料缺乏线粒体DNA,同时在核基因组中具有显着的线粒体ATP合酶基因突变。 方法还包括将线粒体基因组导入缺乏COX1,COX2,COX3或COB基因的非呼吸性酵母以及缺乏COX1,COX2,COX3或COB基因的线粒体基因的转基因酵母。 还公开了另外的方法包括在非呼吸酵母中产生CATS核基因的破坏拷贝以及具有CATS核基因的破坏拷贝的转基因酵母。
