抄録

The extreme thermophile (Thermus thermophilus 111) isolated from a hot spring water was cultured to obtain lipase. The lipase was purified from an extracellular extract and examination was made of some of its properties. Its maximum activity was expressed at pH 7.0 and 65°C. The addition of Ca2+ ions to the reaction mixture increased the rate of hydrolysis. The longer acyl chain was hydrolyzed more quickly than the shorter acyl chain by the lipase. Lipase thermostability was so high that as much as 85 % of the initial activity remained after 10 min at 100°C.
