A study of some properties of the lipase from the seeds ofNigella damascena
- 29 Downloads
1. A lipase isolated from the seeds ofNigella damascena L. showed a pH optimum of 8, a temperature optimum of 37–40°C, a pH stability with an exposure of 30 min in the pH range from 3 to 12 and with exposures of 60 and 120 min in the pH range from 7 to 10. Complete inactivation of the lipase takes place at 80°C.
2. The lipase hydrolyzes a number of plant oils and animal fats well, but has no action on fatty acid esters, ethyl oleate, ethyl acetate, and isopropyl myristate.
