Purification and characterization of phytase from geneticengineering barm 的纯化及性质初步研究
2.
The effects of pressure fermentation on barm propagation , the formation and reduction of diacetyl , the formation of higher alcohols and esters , and beer taste were studied in the experiments 摘要实验研究了压力发酵对酵母繁殖、双乙酰形成及还原、高级醇和酯的形成，以及啤酒口味等方面的影响。

In view of such case , small breweries should form adequate wort cooling procedures , barm expand propagation system and proper fermentation procedures , and establish microbial control monitoring system , which could realize thorough sterilization and washing of facilities and achieve aseptic production to improve beer quality 中小型啤酒厂应建立麦汁冷却工序、酵母扩培系统、发酵工序等工序和生产环节的微生物控制监测管理系统，对工艺过程及设备进行彻底清洗、灭菌，达到生产绝对无菌，提高啤酒质量。
