Fig. 2From: The codon-optimized Δ6-desaturase gene of Pythium sp. as an empowering tool for engineering n3/n6 polyunsaturated fatty acid biosynthesisChromatographic profiles of the yeast transformants carrying pYES2 (upper), pPyDes6 (middle) and pMPyDes6 (lower) plasmids. The transgenic yeasts were cultured in the presence of exogenous fatty acid substrates, LA (a) and ALA (b), and the gene expression was induced by addition of 2 % (w/v) galactoseBack to article page
