Abstract: 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.

Abstract: The invention relates to a process for the production of algal biomass with a high lipid content, comprising: (a) the production of inocula in order to effect phase (b), in photoreactors; (b) the massive cultivation of the algal biomass in open ponds, inoculated with phase (a); (c) a thickening phase of the algal biomass, effected blandly; (d) an induction phase of the lipid production, wherein modules are used consisting of photoreactors or open ponds; (e) a separation phase of the biomass with a high lipid content.

Abstract: Process for the extraction of fatty acids from algal biomass comprising: producing an aqueous suspension of algal biomass; subjecting the aqueous suspension of algal biomass to acid hydrolysis and extraction by the addition of at least one non-polar organic solvent and at least one inorganic acid to said aqueous suspension of algal biomass, so as to obtain the following three phases: (i) a semisolid phase comprising a slurry of the algal biomass; (ii) an aqueous phase comprising inorganic compounds and hydrophilic organic compounds; (iii) an organic phase comprising fatty acids and hydrophobic organic compounds other than said fatty acids.
