Abstract: Described herein is a process of producing an organic compound, the process including: I) cultivating a genetically modified microorganism in a culture medium including sucrose as an assimilable carbon source to allow the genetically modified microorganism to produce the organic compound, and II) recovering the organic compound from the fermentation broth obtained in process step I) The genetically modified microorganism includes A) at least one genetic modification that leads to an increased activity of the enzyme encoded by the rbsK-gene, compared to the original microorganism that has not been genetically modified, and the original microorganism belongs to the family Pasteurellaceae. Also described herein are a genetically modified microorganism and the use thereof for the fermentative production of an organic compound from sucrose as an assimilable carbon source.

Abstract: 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-β-D-glucan synthase-activity, and/or (ii) a polypeptide having 1,3-β-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-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 the polynucleotide, or a polynucleotide encoding a polypeptide having 1,3-β-D-glucan synthase-activity into a microorganism being able to synthesize β-glucans.
