The invention relates to a method for the production of squalene from microalgae belonging to the family ofsp., 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 ofsp. at a temperature of between 25 and 35&#xb0; C., preferably between 28 and 32&#xb0; C., and more preferably of the order of 30&#xb0; C.; and adding between 1 and 1000 &#x3bc;g of vitamin B12 per liter of culture medium to said culture medium.

The invention concerns a strain of, filed on 22 Nov. 2012 with the CNCM as number I-4702, having the ability to produce a high quantity of docosahexaenoic acid (or DHA) and palmitic acid, the methods for producing the corresponding biomass containing said lipid compounds of interest, and the biomass containing the products and compositions prepared from this strain.

[object Object]

A method for preparing a polycarboxylic composition, includes a stage in which a monosaccharide composition undergoes an electrochemical oxidation treatment carried out in the absence of sodium hypochlorite and in the presence of a) an amine oxide and b) a carbon-based anode. Preferably, the anode is selected from the group comprising carbon felt and granular active carbon. The electrochemical oxidation treatment can be carried out advantageously at a pH, preferably of between 11.5 and 14. The method makes it possible to obtain novel products, especially 2-carboxy-2, 3, 4-trihydroxypentane-dioicious acid, the salts and derivatives thereof.

The invention concerns a method for preparing a lactic acid ester composition based on a lactic acid composition involving a step of transforming the composition into a lactic acid oligomeric composition having a mean degree of polymerisation (DPM) ranging between 2 and 30 approximately; and a step which involves mixing and reacting said oligomeric composition with an alcohol, in the presence of a transesterification catalyst, to esterify all or part of the lactic acid contained in said oligomeric composition. The invention also concerns the use of ethyl lactate as solvent for preparing gelified compositions.

Method for preparing a lactic acid ester composition and use thereof as solvent

A process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin with lipophilic compounds, characterized by the fact that the said mixtures are washed with at least one anhydrous polar solvent, whereby at least partial dissociation of the complexes of cyclodextrin/lipophilic compounds is brought about, and the lipophilic compounds which are not included are released from their connection with cyclodextrin.
