| 摘要 |
<p>The present invention relates to a method for producing exopolysaccharides (EPS), comprising pre-cultivating cells of a microorganism, that is capable of producing EPS, in a nutrient medium, separating the cells from the nutrient medium, re-suspending and incubating the cells in a solution preferably comprising the inducer(s) for secretion of EPS forming enzymes, separating the cells from the solution, adding the supernatant to a second solution comprising the substrate(s) and optionally cofactor(s) for EPS formation and incubating, obtaining the EPS. The present invention further relates to an exopolysaccharide (EPS) obtained by the method and its uses in the food industry, pharmaceutics, cosmetic industry, biomedicine or environmental engineering, chemical industry or paper-, materials- or polymer industry. The present invention further relates to the enzymes obtained during the methods of the invention and their uses.</p> |
