Overexpression of D12, D61 and D62 genes. a Structure of plasmids pMAT1552-D12, pMAT1552-D61 and pMAT1552-D62 for D12, D61 and D62 genes overexpressing in M. circinelloides are shown. Black boxes indicate coding region of the desaturase genes. b PCR amplification of genome of control strain (Mc-1552), wide-type strain (M. circinelloides CBS 277.49) and desaturase gene overexpressing strains (Mc-D12, Mc-D61 and Mc-D62) with the primers P3-F and P3-R. Every three transformants in the overexpressing strains and control strain were screened and cultivated in 500 ml flasks containing 100 ml K&R medium for 24 h at 30 °C with shaking at 150 rpm. Then, genomic DNA from these transformants was extracted and verified by PCR amplicfication.
