Research on Arachidonic Acid and Eicosapentaenoic Acid Anabolic Metabolism in Diasporangium sp.

摘要

The fatty acids of a strain of Diasporangium sp.had been analyzed by using GC-MS.The fatty acids of twenty mutants were determined.Based on these results,the producing of eicosapentaenoic acid（EPA）supposed via 18∶2,18∶3,20∶3,20∶4 which all belong to ω-6 fatty acids.The ω-3 desaturation was undertaken at arachidonic acid（AA）.In addition,mutant strains resulted in enhanced content of AA which could get two times more than initial strain,but no compact on EPA.
