Abstract
|
|
|
These experiment were conducted to investigate the characteristics of the purified lipase of Rhizopus japonicus.
1. The optimum pH for the lipase action was 6.8, the stable pH ranged 5.0∼8.0 and the optimum temperature was 35℃. The Purified lipase was stable below 45℃ and inactivated abruptly above 45℃
2. Coconutoil castor oil and palm oil were most favorably hydrolyzed by the purified lipase, wheres olive oil and soybean oil were slightly less than the former three, and Tween 80 was hydrolyzed only 30% compared with coconut oil.
3. The purified lipase was activated by Ca^(++) and Mg^(++), whereas it was inhibited by Hg^(++) and Fe^(++).
