Abstract
There is provided an advantageous process for production of EPA by a gene recombinant technique wherein genes coding for biosynthesis enzymes for eicosapentaenoic acid (EPA) useful as pharmaceuticals, agrochemicals, foods, feeds or the like is obtained from microorganisms.
EPA is produced by obtaining genes coding for eicosapentaenoic acid (EPA) biosynthesis enzymes, constructing a plasmid by joining the genes to a vector, transforming E. coli with the plasmid, and culturing the transformed E. coli.
