Beschreibung
Zusammenfassung:	A process for the extraction of lipids from algal biomass comprising: -producing an aqueous suspension of algal biomass; -adding to said aqueous suspension of algal biomass at least one organic solvent immiscible or substantially immiscible with water obtaining an organic-aqueous mixture; -subjecting said organic-aqueous mixture to evaporation of water and lipid extraction, operating at a temperature such to obtain the substantial complete removal of the water from said organic-aqueous mixture, obtaining: (i) an organic phase comprising lipids and said organic solvent; (ii) a semi-solid phase comprising a residue of said algal biomass.
