Abstract: The invention relates to a method for the production of squalene from microalgae belonging to the family of Thraustochytriales sp., preferably at concentrations of between 2 and 12 g per 100 g of dry biomass. The method is characterized in that it comprises steps consisting in: culturing microalgae belonging to the family of Thraustochytriales sp. at a temperature of between 25 and 35° C., preferably between 28 and 32° C., and more preferably of the order of 30° C.; and adding between 1 and 1000 ?g of vitamin B12 per liter of culture medium to said culture medium.

Abstract: The invention relates to a peptide isolate isolated from a biomass of protein-rich microalgae, characterized in that it comprises: soluble peptides with a molecular weight of between 1 and 20 kDa, a protein content expressed as N.6.25 of more than 95%, essentially arginine and glutamic acid.

Abstract: The invention relates to a method for preparing a composition that is very rich in squalene produced by fermentation of micro-organisms. The method is characterized in that it comprises a purification step selected from the group including: supercritical CO2 extraction in a multi-stage counter-current fractionation column with extract reflux, and short-path molecular distillation.

Abstract: The invention relates to a method for preparing a composition rich in lutein produced by microalgae, particularly microalgae belonging to the Chlorella genus, more specifically produced by Chlorella vulgaris, characterized in that said method includes the sequence of the following steps: 1) preparing a cell lysate from the microalgae biomass; 2) treating the lysed microalgae biomass with a polar solvent, preferably ethyl acetate, in order to obtain an oleoresin containing the lutein and the lipids from the initial biomass; 3) extracting the oleoresin obtained in step 2) by means of a non-polar solvent, here a fluid at supercritical pressure, in order to obtain a fraction rich in non-polar lipids, mainly consisting of triglycerides, and an insoluble fraction rich in lutein; and 4) recovering the thus lutein-enriched fraction.

Abstract: The invention concerns a method of preparing an oil enriched with ethyl esters of DHA produced by fermenting microorganisms, characterized in that it comprises a step of purification by so-called “short path” molecular distillation.
