Abstract

The present invention relates to an improved process for the preparation of unsaturated fatty acids and to a process for the preparation of triglycerides with an increased content of unsaturated fatty acids. The invention relates to the generation of transgenic organism, preferably of a transgenic plant or of a transgenic microorganism, with an increased content of fatty acids, oils or lipids with Δ6 double bonds owing to the expression of a moss Δ-6-desaturase [sic].The invention furthermore relates to transgenic organisms comprising a Δ6-desaturase gene, and to the use of the unsaturated fatty acids or of the triglycerides with an increased content of unsaturated fatty acids prepared in the process.
