  1. 1. Production of 5-ketogluconic acid using recombinant strains of Gluconobacter oxydans

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

    Författare :Aakash Reddy Murugadasan; [2022]
    Nyckelord :Gluconobacter oxydans; Escherichia coli; 5-Keto-D-gluconic acid; Alcohol dehydrogenase; Biotechnology; Biology and Life Sciences;

    Sammanfattning : 5-Keto-D-gluconic acid (5-KGA) is a valuable compound that has a wide range of applications in the chemical and food industries and is commonly used as a precursor for manufacturing tartaric acid (TA). Industrial production of 5-KGA through chemical approaches was practiced in the early 1920’s and was dropped immediately due to several drawbacks because of its complicated process that resulted in lower 5-KGA yield and higher accumulation of impure gluconic acid.

  3. 2. Exploring an alternative metabolic pathway for production of adipic acid - a study on homocitrate synthase

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Damaride Stallone; [2019]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Adipic acid is considered as the most valuable dicarboxylic acid with industrial use; however, its production is heavily petroleum-based. This non-natural metabolite can be produced de novo through different metabolic pathways, one of which is the alpha-ketoacid elongation pathway. LÄS MER

  4. 3. Enabling factors to make ocean wave power a competitive renewable energy source : case studies on modern wave energy companies in Scotland and Sweden

    Master-uppsats, SLU/Dept. of Economics

    Författare :Frencis Karagjozi; Gary Parker; [2016]
    Nyckelord :collaboration; competitive strategy; enabling factors; ocean wave power; renewable energy; wave power technology;

    Sammanfattning : Wave power represents a major source of potential energy to address the global energy demand and modern climate issues. Although it has a huge potential, the current status shows that the source has not been harvested on a commercial scale yet. LÄS MER

  5. 4. Amino Alcohols from Asymmetric Transfer Hydrogenation of α-Amido-β-Keto Esters Possessing Olefins: Formal Total Synthesis of Sphingosine

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Elin Stridfeldt; [2012]
    Nyckelord :Asymmetric transfer hydrogenation; asymmetric catalysis; anti-β-hydroxy-α-amino ester; Sphingosine; cross metathesis;

    Sammanfattning : In this thesis a methodology to synthesize anti-β-hydroxy-α-amino esters possessing olefins has been investigated. The developed procedures originate from two already established procedures in which α-amido-β-keto esters, which do not contain olefins, has been stereoselectively reduced to the corresponding anti-β-hydroxy-α-amino alcohols via asymmetric transfer hydrogenation coupled with dynamic kinetic resolution.

  7. 5. Datorbaserad analys av enzymdesign för Diels-Alder  reaktioner

    Magister-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Philip Olsson; [2011]
    Nyckelord :Diels-Alder; Enzyme Design; Quantum Chemistry; Density Functional Theory DFT ; Protein Docking;

    Sammanfattning : This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. LÄS MER
