  • Publication number: 20160194676
    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-?-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.

  • Patent number: 8399214
    Abstract: The present invention features improved processes and organisms for the production of methionine. The invention demonstrates that a ?metF organism or a ?metE AmetH organism, for example, mutants of C. glutamicum or E. coli, can use a methyl capped sulfide source, e.g., dimethyl disulfide (DMDS), as a source of both sulfur and a methyl group, bypassing the need for MetH/MetE and MetF activity and the need to reduce sulfate, for the synthesis of methionine. Also described in this patent are data implicating MetY (also called MetZ) as an enzyme that incorporates a methyl capped sulfide source, e.g., DMDS, into methionine. A ?metF ?metB strain of C. glutamicum can use a methyl capped sulfide source, e.g., DMDS, as a source of both sulfide and a methyl group. Furthermore, methionine production by engineered prototrophic organisms that overproduce O-acetyl-homoserine was improved by the addition of a methyl capped sulfide source, e.g., DMDS.
