Abstract
A method of fractionating biomass, by permeability conditioning biomass suspended in a pH adjusted solution of at least one water-based polar solvent to form a conditioned biomass, intimately contacting the pH adjusted solution with at least one non-polar solvent, partitioning to obtain an non-polar solvent solution and a polar biomass solution, and recovering cell and cell derived products from the non-polar solvent solution and polar biomass solution. Products recovered from the above method. A method of operating a renewable and sustainable plant for growing and processing algae.
Claims20
A method of fractionating biomass, including the steps of:
- permeability conditioning biomass suspended in a pH adjusted solution of at least one water-based polar solvent to form a conditioned biomass, intimately contacting the conditioned biomass with at least one non-polar solvent, partitioning to obtain a non-polar solvent solution and a polar biomass solution, recovering cell products from the non-polar solvent solution and polar biomass solution and fractionating polar and water soluble components from the biomass.
A method of fractionating biomass, including the steps of:
- permeability conditioning biomass suspended in a pH adjusted solution of at least one water-based polar solvent with at least one enzyme to form a conditioned biomass, intimately contacting the conditioned biomass with at least one non-polar solvent, partitioning to obtain a non-polar solvent solution and a polar biomass solution, and obtaining an end product selected from the group biocrude, soluble monosaccharides, disaccharides, oligosaccharides, polysaccharides, glycerols, amino acids, soluble proteins, peptides, fiber, nutrients, phosphocholine, phosphate, growth media, and residual solid algae cell structural particles.
A method of fractionating biomass including the steps of permeability conditioning biomass suspended in a water solution of carbon dioxide to form a conditioned biomass, partitioning to obtain a non-polar solvent solution and a polar biomass solution, recovering cell products from the non-polar solvent solution and polar biomass solution, and fractionating polar and water soluble components from the biomass.
The method of claim 20, wherein the carbon dioxide is selected from the group including liquid carbon dioxide and supercritical carbon dioxide.
