  1. 11. Deciphering regulatory mechanism influencing qepA efflux pump expression in Escherichia coli

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Jonas Gockel; [2020]
    Nyckelord :qepA; gene regulation; quinolone resistance; class 1 integron; lexA;

    Sammanfattning : QepA is a plasmid-mediated efflux pump found in some strains of Escherichia coli, in which it significantly elevates the resistance against quinolones. The protein has similarities with 14-TMS major facilitator superfamily transporters and is situated in the inner membrane of the bacteria. LÄS MER

  3. 12. Effect of iron redox state on crystallization behaviour of Fayalite slags

    Master-uppsats, KTH/Materialvetenskap

    Författare :Paolo Mai; [2020]
    Nyckelord :Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

    Sammanfattning : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. LÄS MER

  4. 13. Studying genetics of leaf shape variation in Arabidopsis lyrata

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Carina Kvernes Macpherson; [2019]
    Nyckelord :Arabidopsis lyrata; Arabidopsis arenosa; leaf shape; RCO genes; genotype; phenotype; gene sequence variation;

    Sammanfattning : The relationship between leaf and its environment has resulted in a tremendous diversification of leaf shape within and between plants species, which is important to cope with the differing environmental conditions. Arabidopsis lyrata is a prime model plant that shows leaf shape variation within species and between related species. LÄS MER

  5. 14. Increased expression of therapeutic proteins by identification of 3'-UTRs from high expressing genes in CHO cells

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Alexander Westlund; [2019]
    Nyckelord :Mammalian cell; CHO; E. coli; protein expression; plasmid; transformation; Fc-fusion protein; flow cytometry; FACS; transfection; mRNA; UTR; gene engineering;

    Sammanfattning : Therapeutic proteins, a.k.a. biopharmaceuticals, are most commonly produced in expression systems derived from Chinese Hamstery Ovary (CHO) cells, thanks to great capacity of post-translational modifications like secretation, folding and glycosylation. LÄS MER

  7. 15. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
