  1. 16. Thermostable Phytase from a Bacillus sp.: Heterologous Production, Mutation, Characterization and Assay Development

    Författare :Tran Thi Thuy; Bioteknik; []
    Nyckelord :ß-propeller phytase; recombinant protein; site-directed mutagenesis; phytate;

    Sammanfattning : Phytase is an important enzyme in the food/feed industry. It catalyzes the hydrolysis of phytate, an anti-nutrient compound present in cereals and grains, to release orthophosphate and myo-inositol-6-phosphate with lower degrees of phosphorylation. LÄS MER

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

    Författare :Roya Rezaei; Bioteknik; []
    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. 19. Xylan degradation by the thermophilic bacterium Rhodothermus marinus. Characterization and function of a thermostable xylanase

    Författare :Eva Nordberg Karlsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fed-batch cultivation; kraft pulp; bleaching; glycosyl hydrolase family 10; recombinant xylanase; polysaccharide binding domain; Biotechnology; Bioteknik;

    Sammanfattning : A gene encoding a multidomain xylanase from the thermophilic bacterium Rhodothermus marinus has been cloned, sequenced and produced in Escherichia coli . The gene product was found to be a 109 kDa protein consisting of five domains. LÄS MER

  7. 20. Cloning and characterization of human glutaredoxins

    Författare :Mathias Lundberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Reactive oxygen species, ROS, are generated in cells during aerobic metabolism. High and sustained levels of ROS pose a serious threat to all major cellular components, DNA, proteins mid lipids whereas controlled and physiological concentrations play a central role as a second messenger signal molecule involved in cell functions including, differentiation, proliferation, and apoptosis.
