The present technology relates to a method for preparing a mixture of solid potassium salts from a fermentation juice from a fermentation process for the production of chemical compounds in a pH-controlled fermentation medium by adding of a base comprising potassium hydroxide. The method comprises adding an acid to the fermentation juice in an amount sufficient to cause the precipitation of the mixture of potassium salts, and then separating the mixture of salts of potassium solid potassium acidified fermentation juice. The present technology also relates to the mixture of potassium salts obtained by said method and its use as fertilizer.

The present invention relates to the technical field of fertilizer and soil conditioner production, and particularly to a regulating solution, fertilizer and soil conditioner for increasing Vitamin C (abbreviated as Vc, which is also known as ascorbic acid) content of plants as well as a preparation method therefor and application thereof. At the same time, the present invention also relates to a resource utilization technique of wasted liquid in the industrial production of vitamin C. The regulating solution is obtained by regulating the pH value of a wasted gulonic acid mother solution (a residue after evaporation of fermentation liquid from vitamin C industry) or/and 2-keto-L-gulonic acid solution by an alkaline solution, wherein a fertilizer regulating solution is obtained by regulating the pH value of the regulating solution to 3.0-9.0; and a soil conditioner regulating solution is obtained by regulating the pH value of the regulating solution to 2.0-10.0. The regulating solution obtained by the present invention and the fertilizer and soil conditioner prepared by using the regulating solution as a raw material can significantly increase Vc content of plants, and the effect can be found in all plants tested.

Disclosed are methods of dewatering solid byproduct. In some embodiments, the solid byproduct contains particles and is produced from a fermentation process for making an oxygenated compound such as ethanol. The method comprises a chemical sequence for conditioning (pre-treating) the solid byproduct to be dewatered. The solid byproduct (in water) is treated with alkaline material to increase its pH to about 7-8.5. Coagulant is added to the alkaline-treated solid byproduct to reduce charge on the solid byproduct. An agglomerating polymer is then added to increase the average size of the solid byproduct particles to a desired size (e.g., at least about 1 mm). Dewatering can further use known technologies such as screw press, belt press, filter press, centrifuge, and/or a dryer to separate the conditioned or pre-treated byproduct from water. Also disclosed are methods of producing oxygenated product, as well as methods of producing animal feed and/or fertilizer, respectively.

A method for processing raw plant material, especially legumes into protein having a nu-tritional and feed value, bioethanol, biogas and fertiliser materials characterised in that the raw plant material is subjected to a dehusking process, followed by the dehusked raw material being crushed and subjected to extraction with stirring, wherein the insoluble solid fraction is separated and subjected to enzymatic hydrolysis using liquefying and saccharifying enzymes, then subjected to ethanol fermentation, where the produced ethanol is distilled and the digestate is transferred as a substrate for biogas production, and the liquid fraction after the extraction process is subjected to a process of precipitation to a solid form in the form of protein precipitate, which is washed with extraction buffer, after which the liquid residue is removed and subjected to a biogasification process.
