Fig. 1From: Production of eicosapentaenoic acid by application of a delta-6 desaturase with the highest ALA catalytic activity in algaePUFAs biosynthetic pathways modified from Napier [44], where ALA-rich PeSM was added as exogenous substrate in medium to supply a sufficient source of ALA. The abbreviation of desaturases and elongases were described previously [34]Back to article page
