  • Publication number: 20190010523
    Abstract: Disclosed is a process for producing at least one metabolite of interest by conversion of a pentose in a microorganism. The process includes at least: (i) an operation of culturing a recombinant microorganism expressing a synthetic pathway for pentose assimilation which includes at least the following steps: a) phosphorylation in position 1 of a pentose chosen from (D)-xylulose and/or (L)-ribulose, b) cleavage of the pentose-1-phosphate obtained at the end of step a), in order to obtain glycolaldehyde and dihydroxyacetone phosphate (DHAP), and (ii) an operation of recovering the at least one metabolite of interest obtained at the end of the culturing operation (i). Also disclosed is an associated microorganism.

  • Publication number: 20180272116
    Abstract: A bi-directional cannula for perfusing blood in two directions. The cannula has a distal opening in fluid communication with a cannula first lumen. The cannula has a secondary opening proximal of the distal opening, and may include a movable tubular extension selectively extendable from the cannula via the secondary opening. The tubular extension may be in fluid connection with the cannula first lumen and/or a cannula second lumen. The tubular extension may have distal and/or side openings, with the openings providing antegrade fluid perfusion. The cannula second lumen may be separate from the first lumen, so that perfusion can be selectively provided to just the cannula distal opening, just the secondary opening/tubular extension, or simultaneously to both the distal opening and secondary opening/tubular extension.

  • Patent number: 9605283
    Abstract: The invention relates to a modified microorganism for the production of PDO from a carbon substrate wherein the microorganism includes a three-step metabolic pathway including a first step of conversion of 2,4-dihydroxybutyrate (DHB) to obtain 2-oxo-4-hydroxybutyrate (OHB) by an enzyme having 2,4-DHB dehydrogenase activity, a second step of decarboxylation of the OHB to obtain 3-hydroxypropionaldehyde by an enzyme having 2-oxo-4-hydroxybutyrate decarboxylase activity, and a third step of reduction of the obtained 3-hydroxypropionaldehyde to obtain PDO with an enzyme having 3-hydroxypropionaldehyde reductase activity and the genes enabling the microorganism for the synthesis of DHB.
