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

Patent number: 9206348Abstract: A two-stage process for mineral oil production from mineral oil deposits with a deposit temperature of more than 70° C. and a salinity of 20 000 ppm to 350 000 ppm, in which an aqueous formulation comprising at least one glucan with a ?-1,3-glycosidically linked main chain, and side groups ?-1,6-glycosidically bonded thereto and having a weight-average molecular weight Mw of 1.5*106 to 25*106 g/mol, are injected into a mineral oil deposit through at least one injection borehole and crude oil is withdrawn from the deposit through at least one production borehole. The aqueous formulation is prepared in two stages, by first preparing an aqueous concentrate of the glucan, and diluting the concentrate on site with water to the use concentration.Type: GrantFiled: February 13, 2012Date of Patent: December 8, 2015Assignee: WINTERSHALL HOLDING GMBHInventors: Sebastian Briechle, Tillmann Faust, Stephan Freyer, Rajan Hollmann, Tobias Käppler, Bernd Leonhardt, Julia Kristiane Schmidt, Benjamin Wenzke, Foppe Visser
