Fig. 2From: Techno-economic analysis of a new downstream process for the production of astaxanthin from the microalgae Haematococcus pluvialisSchematic presentation of the extraction of astaxanthin into a solvent using a CPE column, including a filling the column with solvent; b equilibration with water; c injection of the algal biomass (zoospores or mechanically disrupted cyst cells); d extraction of astaxanthin from the aqueous algal broth into the solvent, and e fractioning the stationary phase in the elution–extrusion modeBack to article page
