PROCESS FOR THE SELECTIVE PRODUCTION OF POLYUNSATURATED LIPIDS FROM A CULTURE OF MICROALGAE OF THE PORPHYRIDIUM CRUENTUM TYPE

摘要

The invention relates to a process for the selective production of lipids rich in polyunsaturated fatty acids, from a culture of microalgae of the Porphyridium cruentum type. The aim of the invention is to increase the production of biomass produced by this microalga while selectively increasing the quantity of a given polyunsaturated fatty acid, within this biomass. This aim is achieved by means of a process consisting in culturing the microalgae in a photobioreactor (1) under optimal culture conditions, then in subjecting them to a temperature variation in a tank (45) for selective enrichment with polyunsaturated lipids.
