Abstract
A method for producing membrane polysaccharides from an organism selected from micro-organisms, unicellular organisms and filamentous fungi, the method including at least one step of extracting the membrane polysaccharides as well as a smaller-scale extraction of the soluble proteins, by mechanical treatment of the organism in a ball mill or by physical treatment of the organism by means of ultrasounds.

A process for obtaining membrane polysaccharides from an organism selected from microorganisms, unicellular organisms and filamentous fungi, wherein the process comprises at least one step of extracting the membrane polysaccharides, accompanied by a reduced extraction of the soluble proteins, by mechanical treatment of the organism in a ball mill or by physical treatment of the organism by means of ultrasound, and wherein:
- the process is performed by mechanical treatment using a ball mill equipped with glass balls under the following conditions:
- a mean diameter of the balls (dGM) ranges from 1.5×10−3 to 2.5×10−3 m, and
- a stirring speed at a blade end (v) ranges from 5 to 20 m·sec−1, or
- the process is performed by physical treatment by means of ultrasound under the following conditions:
- an energy of the ultrasound ranges from 500 to 5000 J,
- a power of the ultrasound ranges from 200 W to 400 W, and
- a feed flow rate ranges from 0.150 l/min to 3 l/min.
