  1. 1. Metabolic engineering of S. cerevisiae for the production of flavonoids

    Författare :Marta Tous Mohedano; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbial cell factories; high-value products; sustainability; cinnamic acid; plant natural products; Genetic engineering; yeast;

    Sammanfattning : The interest in the production of natural products such as flavonoids has been increasing during the last decade. Flavonoids have several attractive bioactivities including antitumoral, antioxidant or antimicrobial properties. To produce these high-value products, we usually recur to chemical synthesis or plant extraction. LÄS MER

  3. 2. Isolation, Synthesis and Structure-Activity Relationships of Antifeedants against the Pine Weevil, Hylobius Abietis

    Författare :Carina Eriksson; Christina Moberg; John Pickett; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pine weevil; Hylobius abietis; semiochemicals; antifeedant; feeding deterrent; feeding stimulant; bark extract; carboxylic acid; piperidine alkaloids; structure-activity; cinnamic aldehyde; benzaldehyde; Organic chemistry; Organisk kemi;

    Sammanfattning : The large pine weevil, Hylobius abietis L., is a major insect pest on conifer seedlings in northern Europe. Due to its feeding newly planted trees get girdled, resulting in high seedling mortality (up to 80%). As a consequence great financial losses to the forest industry occur. LÄS MER

  4. 3. Teratogenicity Involved in Experimental Diabetic Pregnancy

    Författare :Mattias Gäreskog; Parri Wentzel; Ulf Eriksson; Jonas Cederberg; Kari Teramo; Uppsala universitet; []
    Nyckelord :Cell biology; Diabetes; Pregnancy; PKC; Apoptosis; Rat; Embryopathy; Vitamin E; Folic acid; CHC; NAC; Cellbiologi;

    Sammanfattning : Maternal diabetes is associated with increased risk of growth disturbances and congenital malformations. The malformations rate in the offspring of diabetic mothers is 2-3 fold higher compared to infants of nondiabetic mothers. LÄS MER

  5. 4. Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application

    Författare :Torsten Malmström; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; enantioselective; SAP; hydrogenation; hydroformylation; catalysis; biphasic; rhodium; poly-ethylene imine; poly-acrylic acid; polymers; water-soluble; phosphines; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. LÄS MER

  7. 5. Towards renewable chemicals production in cyanobacteria

    Författare :Kateryna Kukil; Pia Lindberg; Yu Jianping; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; metabolic engineering; succinate; phenylpropanoids; laboratory evolution; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

    Sammanfattning : The intensive fossil fuel combustion by humanity resulted in the increase of atmospheric CO2 concentration creating the greenhouse effect, which in turn causes severe environmental problems. Thus, humanity should find solutions to decrease dependency on fossil hydrocarbons in order to lower CO2 emission into the atmosphere. LÄS MER
