  • Delta 7 and delta 22 cholesterol desaturases from ciliata phylum, and uses
    申请人:Valcarce, German A.
    公开号:EP1251167A2
    公开(公告)日:2002-10-23
    A cell free extract from a ciliate microorganism, including protozoo Tetrahymena, wherein the extract comprises a homogenate a microsomal fraction, a desaturaseenriched fraction or a mixture thereof and, more particularly the invention provides substantially pure enzymes: Δ7 cholesterol desaturases and Δ22 cholesterol desaturase enzymes. The present invention provides methods for decreasing the cholesterol content of a foodstuff of animal origin, such as a dairy product. The methods comprise the step of treating a foodstuff by incubating the same with a cell free extract in a effective amount to enable changes in the foodstuff: (a)reduce the level of cholesterol; and (b) increase the level of at least one desaturated cholesterol derivative: Δ7- dehydrocholesterol, Δ22 dehydrocholesterol and/or Δ7,22 bisdehydrocholesterol. The invention also relates to methods for recovering cholesterol desaturases activities from ciliates, including Tetrahymena, and their use in a production of Δ7 dehydrosterol, Δ22 dehydrosterol and Δ7,22 bis dehydrosterol from several sterol sources as cholesterol.
