  1. 1. Development of a Novel Biocatalytic Cascade for the Valorisation of 5-(Hydroxymethyl)furfural

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Johannes Johansson; [2022]
    Nyckelord :Biocatalysis; Enzyme immobilization; 5- Hydroxymethyl furfural; Transaminase; Galactose Oxidase; Biokatalys; Enzym-immobilisering; 5- hydroxymetyl furfural; Transaminas; Galaktosoxidas;

    Sammanfattning : Den nära förestående bristen på fossila resurser i kombination med deras associerade miljöfarlighet betonar behovet av utveckling av alternativa, mer hållbara kemikalier. I denna studie utvecklades en enzymatisk kaskad för förädling av 5-(hydroxymetyl)furfural (HMF) till 5-(aminometyl)-2-furfuraldehyd (AMFA). LÄS MER

    Sammanfattning : Food waste is gradually becoming a serious global issue in recent decades. It is reported that more than 1.3 billion tonnes of food consisting of around 50 % meat products are wasted every year on a global scale, while there are more than 800 million of the global population who are starving at the same time.

  4. 3. Generation and characterization of a prostate-specific membrane antigen positive eukaryotic cell system for phage selection

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Linda Ehrenborg; [2021]
    Nyckelord :PSMA; Affibody molecules; Directed evolution; phage display; flow cytometry; PSMA; affibody; riktad evolution; fagdisplay; flödescytometri;

    Sammanfattning : Prostate cancer is one of the most common cancer types worldwide. However, current diagnostic approaches and treatments are invasive and unspecific. Prostate-specific membrane antigen (PSMA) is an ideal biomarker for prostate cancer and can act as a target for therapeutic or diagnostic agents. LÄS MER

  5. 4. Biosensor based on immobilized amine transaminase for detection of amphetamine

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Clara Öh; [2020]
    Nyckelord :amine transaminases ATA ; enzyme immobilization; biosensor; covalent immobilization; ionic immobilization; amphetamine; histidine-tagged enzyme; Poly methyl methacrylate PMMA ;

    Sammanfattning : Amine transaminases (ATA) catalyse the transfer of an amino group from one molecule and replaces a ketone or aldehyde with the amino group, the amino group on the amino-donor is replaced with a ketone or aldehyde. This enzyme, ATA from Chromobacterium violaceum, has previously been used to catalyse the reaction involving amphetamine, therefore, it might be possible to use this enzyme to convert amphetamine and the product absorbs in the UV spectrum and can therefore be measured spectrophotometrically.

  7. 5. Nanolithography with molecules using advanced scanning probe microscopy methods

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan Jirlén; [2018]
    Nyckelord :cSPL; AFM; nanolithography; enzyme; starch; amylase; immobilization;

    Sammanfattning : The possibilities of novel catalytic scanning probe lithography (cSPL) on starch using α-amylase was investigated. For this thin homogeneous layers of starch with good coverage were prepared by spin coating a starch solution on a silicon base. LÄS MER
