Fatty acid profile (a) and unsaturation index (b) of the control and recombinant S. cerevisiae strains CEN-RO1 (PTEF-OLE1-reverse) and CEN-O1 (PTEF-OLE1) during the exponential growth phase on glucose (phase 1), lag phase on ethanol (phase 2), ethanol growth phase (phase 3) and stationary phase (phase 4). The unsaturation index was calculated as sum of weight of FA multiplied by the number of unsaturated bonds for each FA in the mixture
