    Abstract: The present invention relates to genetically modified microorganisms capable of producing beta-glucans, characterized in that said genetically modified microorganism overexpresses (i) a polynucleotide encoding a polypeptide having 1,3-β-D-glucan synthase-activity, and/or (ii) a polypeptide having 1,3-β-glucan synthase-activity, compared to a corresponding non-modified control microorganism of the same strain. The present invention also relates to the use of a polynucleotide encoding a polypeptide having 1,3-β-D-glucan synthase-activity or the use of such a polypeptide for producing β-glucans. Furthermore, the present invention relates to methods for producing β-glucans comprising the introduction of a promoter upstream of a polynucleotide encoding a polypeptide having 1,3-β-D-glucan synthase-activity thereby increasing the expression of said polynucleotide, or a polynucleotide encoding a polypeptide having 1,3-β-D-glucan synthase-activity into a microorganism being able to synthesize β-glucans.

    Abstract translation: 本发明涉及能够产生β-葡聚糖的转基因微生物,其特征在于所述遗传修饰的微生物过表达(i)编码具有1,3-β-D-葡聚糖合酶活性的多肽的多核苷酸和/或(ii )具有1,3-β-葡聚糖合酶活性的多肽,与相同菌株的相应未修饰的对照微生物相比较。 本发明还涉及编码具有1,3-β-D-葡聚糖合酶活性的多肽的多核苷酸的用途或这种多肽用于产生β-葡聚糖的用途。 此外,本发明涉及生产β-葡聚糖的方法,包括在编码具有1,3-β-D-葡聚糖合酶活性的多肽的多核苷酸上游引入启动子,从而增加所述多核苷酸的表达,或多核苷酸 将具有1,3-β-D-葡聚糖合酶活性的多肽编码成能够合成β-葡聚糖的微生物。
