Patent number: 9388441Abstract: The present invention relates to genetically modified microorganisms capable of producing beta-glucans, characterized in that the genetically modified microorganism overexpresses (i) a polynucleotide encoding a polypeptide having 1,3-?-D-glucan synthase-activity, and/or (ii) a polypeptide having 1,3-?-D-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-?-D-glucan synthase-activity or the use of such a polypeptide for producing ?-glucans. Furthermore, the present invention relates to methods for producing ?-glucans comprising the introduction of a promoter upstream of a polynucleotide encoding a polypeptide having 1,3-?-D-glucan synthase-activity thereby increasing the expression of the polynucleotide, or a polynucleotide encoding a polypeptide having 1,3-?-D-glucan synthase-activity into a microorganism being able to synthesize ?-glucans.Type: GrantFiled: March 18, 2016Date of Patent: July 12, 2016Assignees: BASF SE, Wintershall Holding GmbHInventors: Beata Brockmann, Andrea Herold, Oskar Zelder, Stefan Haefner, Christian Fleck, Hartwig Schröder, Mari Granström, Julia Kristiane Schmidt
