The invention relates to a process for the selective production of polyunsaturated fatty acids from a culture of microalgae of Porphyrium cruentum. The process comprises growing a biomass by culturing the microalgae in a photobioreactor under optimum culturing conditions, removing a portion of the resulting biomass, and subjecting the removed portion to a temperature decrease. The result is the selective increase in the quantity of a given polyunsaturated fatty acid within the microalgae biomass. |
