一般描述

来自 酿酒酵母的酵母 (Baker′s 酵母)是最古老的微生物发酵剂。[1]为兼性厌氧菌。[2]

应用

来自 酿酒酵母 的酵母已被用于:
  • 作为酵母微生物燃料电池阳极的生物催化剂 [3] [4]
  • 用于生产燃料用乙醇 [5]
  • 制备酵母提取物[6]

生化/生理作用

酿酒酵母(Baker酵母)的酵母用作蛋白质补充剂,能量增强剂和免疫增强剂。[7]它通过将可发酵的糖转化为 CO2和乙醇,在面包生产中用作面团发酵剂。[8] Baker酵母具有香气、抗霉菌和营养特性。[1]它可以作为细胞工厂。[9]

注意

在 37°C 水性缓冲液中自溶。

制备说明

Questions

1–2 of 2 Questions  
  1. Hi We would like to expand this yeast in our lab for an experiment. Would you please recommend best growth media for expanding this Yeast.

    1 answer
    1. This product is specifically prepared to undergo autolysis in aqueous buffer solution at 37°C, optimized for retaining enzyme activity post-drying, though not for cell viability or growth. It serves as an excellent starting point for enzyme extraction processes. For proliferation, Product YSC2 is a viable baker’s yeast, ready to grow once rehydrated, with only about 10% subject to autolysis at the same temperature. It is the preferred option for those looking to cultivate yeast effectively.

      Helpful?

  2. What are the differences between YSC1 and YSC2?

    1 answer
    1. YSC1 is dried to prevent enzyme inactivation during enzyme extractions from yeast. On the other hand, YSC2 is fast dried and yields 90% viable cells in solid form. The primary difference lies in the method of preparation, particularly in the drying process.
