The invention relates to a method for purifying a mixture to be separated, in a multicolumn chromatography system, the method comprising successively and cyclically: a step of collecting a raffinate, a step of injecting the mixture to be separated, a step of collecting an extract and an eluent injection step, at an operating temperature; wherein the mixture to be separated has a viscosity at 20? C. greater than or equal to 3 mPa.Math.s; and wherein the dry matter mass concentration of the mixture to be separated is equal, within 5%, to a threshold concentration, said threshold concentration is such that: the viscosity of the mixture to be treated at a dry matter mass concentration equal to the threshold concentration and at the operating temperature, is equal to twice the viscosity of the mixture to be treated, at a dry matter mass concentration equal to 85% of the threshold concentration and at the operating temperature.

A composition includes a sugar source and inositol. The sugar source is one more sugars select from the group consisting of glucose, sucrose, sucrolose, tagatose, galactose, high fructose corn syrup, fructose, isoglucose, and rhamnose. The composition of sugar and inositol has an unique properties that prevents or limits the signaling of TNF-? and associated pro-inflammatory cytokines when metabolized by an individual consuming the composition. Accordingly, the composition can be advantageously used to control blood glucose levels, treat diabetes and related conditions as well as treat diseases based on an inflammatory response.

Process for the extraction of lipids and sugars from algal biomass, which comprises: producing an aqueous suspension of algal biomass; bringing the pH of said aqueous suspension of algal biomass to a value higher than or equal to 10, preferably ranging from 10.2 to 12, obtaining an aqueous suspension of algal biomass at basic pH; adding at least one anionic flocculant to said aqueous suspension of algal biomass at basic pH obtaining a concentrated algal biomass; recovering said concentrated algal biomass; subjecting said concentrated algal biomass to extraction of the lipids obtaining: (i) an organic phase comprising lipids; (ii) a semi-solid phase comprising a residue of said algal biomass; subjecting said semi-solid phase (ii) to hydrolysis obtaining sugars. The lipids thus obtained can be advantageously used in the production of biodiesel or green diesel which can be used as such, or in a mixture with other fuels for motor vehicles. The sugars thus obtained can be advantageously used as carbon sources in fermentation processes for the production of lipids and also for the production of alcohols (e.g., ethanol, butanol). Said alcohols can be advantageously used as biofuels for motor vehicles or as components that can be added to fuels for motor vehicles.

A material pretreatment method using low-temperature extrusion and multienzyme synergistic degradation. A to-be-extruded material added with enzyme preparations and having a certain moisture content is blended before extrusion, the to-be-extruded material is fed into a screw extrusion device and is to be subjected to low-temperature extrusion treatment, multiple enzyme preparations are added in the material before extrusion, and starch, cellulose, protein and other substances in the material are degraded under the synergistic effect of the added multiple enzyme preparations in an extrusion process. Compared with the prior art, the yield of glucose and maltose converted from starch is improved, the residual oil rate of oil material meals is reduced, soluble substances of plant fiber materials are increased, and compared with the process of the traditional technology, the time needed in converting a protein material into a polypeptide material is shortened.

The present disclosure generally relates to compositions and methods of simultaneously making two unique biointermediates from a single lignocellulosic biomass feedstock, including a hydrophobic biohydrocarbon and a water insoluble hydrophilic cellulosic biopolymer for use in the production of renewable fuels, chemicals, and other carbon neutral materials commonly derived from petroleum and other fossil resources.
