  1. 1. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

    Författare :Nina Johansson; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

    Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER

  2. 2. Feruloyl esterases - Evaluation of their potential for biotechnological applications

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Cyrielle Bonzom; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-domain enzyme; acetyl esterase; enzyme immobilization; N-glycosylation; carbohydrate active enzyme family 1; acetyl xylan esterase; heterologous production; polysaccharide utilization loci; enzyme stability; feruloyl esterase;

    Sammanfattning : Owing to the current efforts to find sustainable alternatives to petrochemical based industries and technologies, enzymatic degradation and valorization of plant biomass has been attracting interest. Due to the complexity of plant biomass, an array of enzymes is required to hydrolyze it, including esterases. LÄS MER

  3. 3. Ribosomes and subunits from Escherichia coli studied by asymmetrical flow field-flow fractionation

    Detta är en avhandling från Technical Analytical Chemistry, Lund University

    Sammanfattning : In this thesis asymmetrical flow field-flow fractionation (FFF) separations of ribosomes and subunits have been studied. Ribosomal material was prepared from Escherichia coli (E. coli) cells and analyzed by the size separation technique. LÄS MER

  4. 4. Bio-based C-3 Platform Chemical: Biotechnological Production and -Conversion of 3-Hydroxypropionaldehyde

    Detta är en avhandling från Lund University

    Författare :Roya Rezaei; Lund University.; Lunds universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lactobacillus reuteri; 3-hydroxypropionic acid; biotransformation; Glycerol; 3-hydroxypropionaldehyde; In situ complexation;

    Sammanfattning : Demands for efficient, greener, economical and sustainable production of chemicals, materials and energy have led to development of industrial biotechnology as a key technology area to provide such products from bio-based raw materials from agricultural-, forestry- and related industrial residues and by-products. For the bio-based industry, it is essential to develop a number of building blocks or platform chemicals for C2-C6 chemicals and even aromatic chemicals. LÄS MER

  5. 5. Selenocysteine in proteins : Properties and biotechnological use

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Medical Biochemistry and Biophysics

    Författare :Linda Johansson; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selenocysteine; recombinant selenoprotein production; thioredoxin reductase; enzymology; protein labeling; mite allergy; mouse model;

    Sammanfattning : Selenocysteine (Sec), the 21st amino acid, exists in all kingdoms of life and has unique biochemical properties, such as high electrophilicity and low pKa. The highly increased reactivity of selenoenzymes compared to their sulfur-containing cysteine-dependent homologs is generally regarded as the evolutionary reason for having selenoproteins. LÄS MER
