    摘要: Isomaltulose-forming microorganisms are immobilized on a carrier that is a weakly basic anion exchange substance in the form of a substantially non-compressible porous particulate solid material, and are used for isomerization of sucrose to isomaltulose. A preferred carrier contains microfibers or microparticles of diethylaminoethyl cellulose adherently bound by agglomeration with polystyrene. The isomerization may be a continuous conversion in one or more columns packed with the carrier. Isomaltulose may be hydrogenated to form isomalt for use in sweetening. Microorganisms can be immobilized on the carrier by feeding microorganisms to a column containing the carrier. After microorganism immobilization, the carrier may be treated with a crosslinking and/or flocculating compound. Regeneration of the carrier is carried out by removing microorganisms, washing and reloading with fresh microorganisms.

    摘要: The invention relates to a method for preparing pure lactic acid or a salt thereof by fermentation. The preparation process comprises bioreactor refreshing cycle and a lactic acid production cycle, wherein during the production cycle a solution comprising substantially pure feedstock is recycled through a bioreactor containing refreshed microorganism cells, the lactic acid produced being neutralized by adding an alkali, and the recycling is discontinued when the alkali consumption is substantially diminished, and during the refreshing cycle the microorganism cells are refreshed by recycling through the bioreactor a carbohydrate solution enriched with nutrients, thus replenishing the capacity of the microorganisms to produce an acid, and recovery of lactate or conversion thereof into lactic acid or other salt.

    摘要: The invention relates to a process for fractioning vinasse, in which process the pH value of the vinasse is lowered by adding acid, and the formed precipitate is separated in order to obtain an inorganic fraction, whereupon an organic fraction remains. The invention also relates to the products obtained. The inorganic fraction mainly contains potassium salt, and it is useful for example as a fertilizer. The organic fraction mainly contains organic acids, and it is useful for example as an additive in animal feed and in producing silage.

    摘要: The invention relates to a process for preparing vinasse suitable for a column process, in which process dilute vinasse is clarified by means of a high-efficiency centrifuge, after which the vinasse is concentrated and potassium is removed. The invention also relates to the vinasse and the potassium sulphate crystals prepared with the above-described process.
