低温度

High temperature is disadvantageous for the disproportionation of CO, and decreases the conversion significantly due to the limitation of thermodynamic equilibrium.

在实验条件下，因温度较高对CO的歧化不利，受热力学平衡的限制，CO虽能歧化但反应的转化率很低。

Diacetyl is signal products of ripeness of beer fermentation and proper content of higher alcohols could make beer products full and mild in taste, but excessive higher alcohols not only bring beer peculiar smell but also make beer toxic and ebriety caused by alcohols, so superscale of diacetyl and higher alcohols had become restrictive factors and outstanding contradictions of improving beer qualities, especially in producing low cost beer products fermented by elevating fermentation temperature, shortening fermentation period and increasing content of subsidiary materials.

双乙酰也是啤酒发酵成熟的标志物质，过量的双乙酰给啤酒带来不愉快的"馊饭味"，而适量的高级醇可使酒体丰满圆润、口感柔和协调，但高级醇含量过高，不仅会给啤酒带来异杂味，还易发生醇类中毒，导致醉酒。因此，双乙酰和高级醇超量已成为制约啤酒质量的重要因素，特别是在提高温度、缩短周期、增加辅料的低成本快速发酵中，这一问题更加突出。
