Abstract:
A method to process microalgae biomass and produce high-value chemicals from microalgae biomass is disclosed. The method uses the same biomass cells to extract more than one component such as are lipids, water-soluble chemicals, carotenoids, polysaccharides and algae meal. The method is a sequence of physical and chemical treatments. Water soluble polysaccharides produced by the method exhibit properties of low viscosity at low shear thinning. A method for extracting dietary fiber from microalgal biomass is disclosed. Compositions of water-soluble polysaccharides that are fermented slowly by colon microbiota with less gas production than commercial dietary fiber FOS are disclosed. The present inventions described herein provide a method of improving colon health by increasing butyrate during a microalgal dietary fiber fermenting process by colonic microbiota.

Claim (Index 2):
A method to extract and isolate compounds from an algal biomass comprising:\n physically treating the algal biomass by micro fluidization or ultra-sonication with a frequency greater than 20 KHz using a probe-type sonication or bath sonication, optionally in combination with extrusion using an extruder or with addition of a solvent, wherein the solvent is hexane, followed by centrifugation, wherein centrifugation was performed at a speed of about 500 rpm to about 15000 rpm, wherein centrifugation was performed at a speed of about 1000 rpm to about 10000 rpm, wherein centrifugation was performed at a speed of about 2000 rpm to about 5000 rpm, followed by extracting lipids and other oils from the top, the water soluble chemicals from the middle and the pellet from the bottom, hydrothermally treating the pellet by heating at high pH, optionally in combination with high pressure, while stirring, followed by centrifugation of the hydrothermally treated pellet at 2500 rpm for 10 minutes or 4000 rpm for 15 min, separating the supernatant from the resulting residue, precipitating water-soluble polysaccharides from the supernatant, wherein the precipitated polysaccharides were washed and pH adjusted to about 7, and dried, extracting carotenoids from the resulting residue using solvent.
