Summary of the technology
CSIC has developed a procedure to extract bioactive compounds from
wet biomass, in example
microalgae or/and seaweeds, by using a sequential methodology. The procedure is quick, selective, give
high yields, maintain bioactivity and minimize the impact to the environment.
Industrial partners from the chemical or pharmaceutical or food industry are being sought to
collaborate through a patent licence agreement.

A Sustainable Extraction of Bioactives from Algae
A seaweed Extraction of biomass is performed in sequential steps comprising supercritical fluid extraction, pressurized liquid extraction, and subcritical extraction.
Wet biomass could include microalgae or seaweeds. For the compounds of interest quantified (lipids, proteins, sugars and the pigment fucoxanthin), recoveries reached values greater than 80% of lipids and 70% fucoxanthin present in algal biomass recovery.
In terms of the content of proteins and sugars, the process corresponding to the present invention allows to recover a percentage of proteins more than 18% and a 35% percentage of sugars from the algal biomass.
The residue of the sequential extraction contains mainly sugars and proteins.
Main innovations and advantages
· Bioactive extraction yields are clearly superior to those obtained usingthe procedure from dry biomass (lyophilized) · The usual previous dry treatment of the biomass is avoided.
· Solvents are eliminated during the process to preserve releasedcompounds from deleterious oxidation.
