An engineered microorganism comprising a first nucleic acid sequence encoding an elongase and a second nucleic acid sequence encoding a desaturase, wherein the first and second nucleic acid sequences are operably linked to a delta 9 desaturase promoter.

A method of promoting conversion of saturated fatty acids to unsaturated fatty acids comprising the steps of

• (a) transforming an oil-producing microorganism with a construct comprising a first nucleic acid encoding an elongase and a second nucleic acid encoding a desaturase, wherein the construct is inserted into the genome of the oil-producing microorganism at a location wherein expression of the encoded elongase and desaturase is controlled by a promoter native to the oil-producing microorganism;
• and
• (iii) culturing the transformed microorganisms under conditions to produce fatty acids, wherein the transformed microorganisms convert saturated fatty acids to unsaturated fatty acids greater than a control untransformed microorganism.
