  1. 1. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Robert Liao; [2023]
    Keywords : ;

    Abstract : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.

  3. 2. Ultrasound pre-treatment of wheat bran to improve arabinoxylan extraction

    University essay from SLU/Department of Molecular Sciences

    Author : Louise Lundquist; [2022]
    Keywords : Ultrasound; Arabinoxylan; wheat bran; alkaline extraction;

    Abstract : With increasing amounts of food waste and diet related diseases, the need to utilize our by-products of food for its health benefits and to limit the food waste has never been more prevalent. Wheat bran is a by-product from the wheat flour industry and contains a lot of dietary fibres which has a beneficial effect on human health. READ MORE

  4. 3. Evaluating Sugar Signaling during Xylose Oxidation in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Viktor Persson; [2020]
    Keywords : Saccharomyces cerevisiae; yeast; xylose oxidation; sugar signaling; biosensor; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The sugar signaling state of cells oxidizing xylose was investigated through the chromosomal integration of the Weimberg pathway into previously established biosensor strains capable of monitoring the Snf3p/Rgt2p, SNF1/Mig1p, and cAMP/PKA pathways through the expression of HXT1, SUC2, and TPS1, respectively. Ultimately, two new strains were successfully developed containing both the Weimberg pathway and a biosensor for either HXT1 (TMB CB 112) or TPS1 (TMB CB 117). READ MORE

  5. 4. SYNTHESIS OF β-D-RIBOPYRANOSIDES DERIVATIVES FROM β-D-XYLOPYRANOSIDE

    University essay from Lunds universitet/Kemiska institutionen

    Author : Christopher Musonda; [2018]
    Keywords : organic chemistry; organisk kemi; xylos; träsocker; proteoglykan; Chemistry;

    Abstract : The aim of this thesis was to synthesize various β-D-ribopyranoside derivatives with different C-4 functional groups, using D-xylose as the starting material. The desired modifications were deoxygenation, fluorination, methylation and epimerization of the C-4 hydroxyl group. READ MORE

  6. 5. FTIR- och Ramanspektroskopi som analysmetod för den kemiska sammansättningen av granved : en jämförelse

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Edward Carlsson; Douglas Kärrholmen; [2018]
    Keywords : vibrationsspektroskopi; korsvalidering; vedkemi; absorbtion; närinfraröd;

    Abstract : Den kemiska sammansättningen har en central påverkan på egenskaper och användningsområden för trä. För att kunna uppfylla dagens krav för vedens kemiska sammansättning krävs billiga och effektiva analysmetoder. READ MORE
