The effects of a live strain of Saccharomyces cerevisiae on hydrogen utilization and acetate and methane production by two hydrogenotrophic ruminal microorganisms, an acetogenic bacterial strain and an archaea methanogen, were investigated. The addition of yeast cells enhanced by more than fivefold the hydrogenotrophic metabolism of the acetogenic strain and its acetate production. In the absence of yeasts, and in a coculture of the acetogen and the methanogen, hydrogen was principally used for methane synthesis, but the presence of live yeast cells stimulated the utilization of hydrogen by the acetogenic strain and enhanced acetogenesis.
研究了酿酒酵母的一种活菌株对两种氢营养型瘤胃微生物（一种产乙酸细菌菌株和一种古生甲烷菌）利用氢气以及乙酸和甲烷产生的影响。添加酵母细胞使产乙酸菌株的氢营养代谢及其乙酸产量提高了五倍以上。在没有酵母的情况下，以及在产乙酸菌和产甲烷菌的共培养中，氢气主要用于甲烷合成，但活酵母细胞的存在刺激了产乙酸菌株对氢气的利用并增强了产乙酸作用。
