摘要
嗜热菌ＢＡＥ２产生热稳定的淀粉酶，研究表明它的最适温度为８５℃，在ｐＨ５～９的范围内酶活力有很高的稳定性，在无添加剂存在的情况下，酶于８０℃稳定，通过添加乙二醇、甘油、甘露醇及聚乙二醇６０００，可使酶于９０℃非常稳定。
Thermophile BAE, produces thermostable amylase. This enzyme has the optimal reaction temperature of 85℃, and stable in pH range of 5-9. The enzyme is stable at 80℃ in the absence of any stable additive, however it's very stable at 90-℃ when in the presence of organic additives such as ethanol glycol, glycerol, and PEG6000.
