摘要：
This production and extraction process comprises a polysaccharide concentration stage consisting in leaving the culture medium (1) in a photo reactor (22) exposed to sunlight in stagnant conditions and at room temperature, entailing the formation of a polysaccharide-rich cream (23), and in recovering the said cream by skimming-off, a stage of heating (24) of the concentrate obtained to a temperature ranging from 60 to 100 DEG C, a stage of separation of the solid and liquid phases formed (26), a stage of precipitation of the polysaccharides (30) present in the liquid phase and a stage of drying (16) the precipitate obtained.
