Claims15
A process for extracting lipid containing products from microalgal biomass, the process comprising:
- (i) treating an aqueous mixture comprising microalgal biomass with microwave radiation and (ii) recovering lipid containing products from the treated microalgal biomass.
A process for extracting lipid containing products and carbohydrate containing products from microalgal biomass, the process comprising:
- (i) providing an aqueous mixture containing the microalgal biomass;
- (ii) adjusting the pH of the aqueous mixture to pH<7;
- (iii) heating the aqueous mixture containing the microalgal biomass;
- and (iv) separating the lipid containing products and the carbohydrate containing products from the biomass.
A process for extracting lipid containing products and protein containing products from microalgal biomass, the process comprising:
- (i) providing an aqueous mixture containing the microalgal biomass;
- (ii) adjusting the pH of the aqueous mixture to pH>7;
- (iii) heating the aqueous mixture containing the microalgal biomass;
- and (iv) separating the lipid containing products and the protein containing products from the biomass.
A process for extracting lipid containing products, carbohydrate containing products, and protein containing products from microalgal biomass, the process comprising:
- (i) providing an initial aqueous mixture containing the microalgal biomass;
- (ii) adjusting the pH of the initial aqueous mixture to pH<7;
- (iii) heating the acidic initial aqueous mixture containing the microalgal biomass to provide a first treated mixture;
- (iv) separating the solid and the liquid from the first treated mixture to provide a first solid and a carbohydrate containing liquid;
- (v) combining the first solid with an aqueous mixture to form a second aqueous mixture containing microalgal biomass;
- (vi) adjusting the pH of the second aqueous mixture to pH>7;
- (vii) heating the alkaline second aqueous mixture containing the microalgal biomass to provide a second treated mixture;
- (viii) separating the solid and the liquid from the second treated mixture to provide a second solid and a protein containing liquid;
- (ix) optionally, repeating steps (v) to (viii) using the second solid to provide a third solid and a further protein containing liquid;
- (x) combining the second solid or the third solid with an aqueous mixture to form a final aqueous mixture;
- (xi) treating the final aqueous mixture with a solvent;
- (xii) Separating the solvent from the final aqueous mixture to provide a solvent containing lipid product.
