  2. 1. Xylan degradation by the thermophilic bacterium Rhodothermus marinus. Characterization and function of a thermostable xylanase

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Mechanistic design of structural elements controlling proton pumping in cytochrone c oxidase

    Author : Håkan Sigurdson; Michael T. Wilson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biogeochemistry; biogeokemi;

    Abstract : Cytochrome c oxidase is the last component of the respiratory chain in mitochondria and many bacteria, where it catalyses the reduction of O2 to water. The structures of cytochrome c oxidases from a number of organisms such as bacteria and cow, are known and show remarkable similarities in both structure and function. READ MORE

  6. 4. Antimicrobial potential of Geobacillus sp. ZGt-1 isolated from Zara hot spring in Jordan : Piecing the puzzle of the antagonistic activity of a novel bacterial strain

    Author : Rawana Alkhalili; Bioteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermophiles; Geobacillus; antimicrobial potential; antimicrobial peptides; bacteriocins; lanthipeptides; toxin-antitoxin; genome sequence;

    Abstract : The problem of antibiotic resistance is rising continuously, creating a warning signal that calls for finding alternatives. Not only that, but there is also a rising demand for natural food preservatives. The pharmaceutical and food industry sectors are working on fulfilling these needs. This thesis is exploring possible solutions to these issues. READ MORE

  7. 5. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

    Author : Zubaida Gulshan Kazi; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

    Abstract : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. READ MORE
