  1. 1. Recombinant expression of the cowpea chlorotic mottle virus

    University essay from Lunds universitet/Kemiska institutionen

    Author : Amanda Willas; [2019]
    Keywords : Biokemi; Biochemistry; Viruskapsid; Viruscaspid; CCMV; Chemistry;

    Abstract : All viruses are composed of both genetic material and a capsid. The capsid is composed by identical protein subunits and the purpose is protection of the genetic material, in this case RNA. READ MORE

  2. 2. Purification and refolding of a novel dipeptidyl peptidase III

    University essay from Linköpings universitet/Kemi

    Author : Lennie Jansson; [2019]
    Keywords : dipeptidyl peptidase III; DPP III; purification; refolding; protein; Arg-Arg-2NA;

    Abstract : There is a continuous search for novel enzymes to complement the abilities of today’s commercially available enzyme and find tailor-fit alternatives to suit the diverse array of bio-based industries. One application could be to increase biogas yield by finding substrate degrading proteases that can be added to the anaerobic digestion process and survive degradation themselves. READ MORE

  3. 3. Essential oils and phenolic compounds as food preservatives

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Erika Häggman; [2019]
    Keywords : Origanum; Thymus; thymol; carvacrol; secondary metabolites; bacteria; foodborne; phenols; antimicrobial;

    Abstract : Recent studies have shown that consumers are increasingly choosing food items without synthetic preservatives or additives. In order to find alternatives to address the food industry’s need of ensuring food safety, this essay focuses on the possible use of natural preservatives derived from antiseptic plants. READ MORE

  4. 4. Polyvinylalcohol-carbazate (PVAC) inhibits bacteria growth

    University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Author : Jakob Syk; [2019]
    Keywords : Turbidity; spectrophotometric assay; FITC; antibodies; qPCR;

    Abstract : Abstract Introduction This study evaluated the effect of the polymer polyvinylalcohol-carbazate (PVAC) on the bacteria Escherichia coli, Staphylococcus aureus, Staphylococcus epidermidis and Pseudomonas aeruginosa. PVAC is a polymer with a carbazate moiety that neutralizes free aldehydes and has shown great promise in stabilizing erythrocytes during long term storage. READ MORE

  5. 5. Development of a single-molecule tracking assay for the lac repressor in Escherichia coli

    University essay from Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Author : Oscar Broström; [2019]
    Keywords : Escherichia Coli; Single-molecule fluorescence microscopy; In vivo tracking; In vivo; lac repressor; LacI; Bifunctional rhodamine B; E. coli; In vivo;

    Abstract : Gene regulation by transcription factors are one of the key processes that are important to sustain all kinds of life. In the prokaryote Escherichia coli this has shown to especially crucial. The operator sequence to which these transcription factors bind to are very small in comparison to the whole genome of E.
