  1. 6. Exploratory study of ion pair liquid chromatography separation methods and sample preparation procedures – for quantification of amount 5’capped and uncapped mRNA

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Felicia Lindström; [2023]
    Nyckelord :;

    Sammanfattning : Using ion pair chromatography, separation and analysis of shorter mRNA fragments was possible. The aim of the study was to develop a separation method for quantitation of 5’capped versus uncapped mRNA. Cleavage of mRNA was performed by complementary probes and the enzyme RNase H which created shorter mRNA fragments containing the 5’ end. LÄS MER

  3. 7. Identification of Vanadium-Binding Ligands in White Wine

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Freja T Trybom; [2023]
    Nyckelord :Vanadium; LD converter slag; wine; food waste; recycling.;

    Sammanfattning : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. LÄS MER

  4. 8. A novel approach for functionalising and separating Tröger's Base Analogues

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Emil Jakobsson; [2023]
    Nyckelord :Tröger s Base; Synthesis; Chromatography; Supramolecular chemistry; Diastereomers; Organic chemistry; Chemistry;

    Sammanfattning : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. LÄS MER

  5. 9. Geobacillus 7349 – A new potential biosurfactant producing microorganism

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Zhuoying Deng; [2023]
    Nyckelord :biosurfactant; rhamnolipids; HPLC; HPAEC-PAD; bacteria growth; downstream purification; liquid-liquid extraction; biotechnology; Chemistry;

    Sammanfattning : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. LÄS MER

  7. 10. Cultivation of Yarrowia lipolytica on a hydrolysate based on food waste

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Hanna Norrman; [2023]
    Nyckelord :Yarrowia lipolytica; hydrolysate; food waste; fish feed; volatile fatty acids;

    Sammanfattning : Interest in replacing fish oil and fish meal as fish feed ingredients with more socially, environmen-tally, and economically sustainable alternatives has increased in recent years. One such alternative could be the use of yeast biomass. LÄS MER
