  1. 1. Production and investigation of highly thermophilic multi-domain carbohydrate-active enzymes

    Författare :Daniel Krska; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure; xylanase; carbohydrate esterase; multidomain enzymes; carbohydrate-active enzymes; thermostable enzymes; plant biomass degradation; Caldicellulosiruptor;

    Sammanfattning : With the looming threat of climate change caused largely by an excess of carbon dioxide in the atmosphere, recent scientific efforts have focused on the substitution of fossil fuels and other polluting compounds with more environmentally conscious choices. To this end, the investigation of biomass as both a renewable source of energy and as a chemical basis to produce high-value products is being extensively investigated. LÄS MER

  3. 2. Diversity of thermostable DNA enzymes from Icelandic hot springs

    Författare :Sigridur Hjorleifsdottir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermophiles; microbial diversity; SSU rRNA; Thermus; hot springs; Biotechnology; Bioteknik; Biochemistry; enzymologi; Proteiner; enzymology; metabolism; Proteins; DNA enzymes; Biokemi;

    Sammanfattning : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. LÄS MER

  4. 3. Glycoside hydrolases from extremophiles isolated in Iceland. alpha-L-Rhamnosidases and pectin degrading enzymes

    Sammanfattning : Extreme environments (high and low temperature, high and low pH, etc.) are inhabited by a vast and diverse flora of microorganisms, which are adapted to these environments (extremophiles). LÄS MER

  5. 4. Glycoside hydrolases from Rhodothermus marinus Modular organisation and structure-function relationships

    Författare :Maher Abou-Hachem; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium-binding; modular; endoglucanase; thermostable; CBM; xylanase; Biotechnology; Bioteknik;

    Sammanfattning : The thermophilic bacterium Rhodothermus marinus produces several thermostable glycoside hydrolases. The studies presented in this thesis were performed on two enzymes, belonging to glycoside hydrolase families 10 and 12, produced by this microorganism. The family 10 xylanase, Xyn10A, is modular in architecture consisting of five domains or modules. LÄS MER
