    Författare :Anton Pallin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fermentation of foodstuffs has beneficial effects on shelf life, taste and texture and possibly also health of the consumer. Products containing microbes with beneficial health effects for the host are defined as probiotics. LÄS MER

  3. 12. Glycerol derivatives in the hydrogen autotransfer reaction - Development of C-C and C-N bond forming reactions

    Författare :Anna Said Stålsmeden; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amination; organic synthesis; sustainable precursors; alkylation; hydrogen autotransfer; glycerol;

    Sammanfattning : Glycerol (1,2,3-propanetriol) is obtained as a byproduct in the biodiesel industry. In the quest for more sustainable starting materials for organic synthesis, glycerol with its three alcohol functionalities is a promising candidate. LÄS MER

  4. 13. Microbial production of 3-hydroxypropionic acid and poly(3-hydroxypropionate): Investigation of Lactobacillus reuteri propanediol utilization pathway enzymes

    Författare :Ramin Sabet Azad; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platform chemicals; biopolymers; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; glycerol; poly 3-hydroxypropionate ; polyhydroxyalkanoates; Escherichia coli; Lactobacillus reuteri; propanediol utilization pathway; propionaldehyde dehydrogenase; biotransformation; cofactor regeneration; NADH oxidase;

    Sammanfattning : Concerns regarding environmental issues such as greenhouse gas emissions and climate change have led to a shift within the research community and chemical and energy industry sectors for finding sustainable routes for producing fuels and chemicals from renewable resources, thereby minimizing our dependence on petroleum. The C3-chemical 3-hydroxypropionic acid has been identifed as a top candidate for the biobased chemical industry. LÄS MER

  5. 14. 13C-Enriched Dehydrogenation Polymers Used for Studying Light-Induced Yellowing of Lignocellulosic Materials

    Författare :Jim Parkås; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lignin model compounds; differentiating xylem; yellowing; Picea abies; 13C NMR spectroscopy; lignin; DHP; 13C-enrichment; solid state; spruce;

    Sammanfattning : This study deals with the use of selectively 13C-enriched dehydrogenation polymers (DHPs) as models of lignin in lignocellulosic materials for elucidating the reaction pathways involved in light-induced yellowing. Methods for the synthesis of coniferin, a precursor to lignin and DHP, selectively 13C-enriched in the aromatic ring (positions 1, 3, 4, and 5) have been developed. LÄS MER
