  1. 1. An Alkaline Active Endo-Xylanase from Bacillus halodurans S7:Molecular and Structural Aspects

    University dissertation from Biotechnology, Lund University

    Author : Gashaw Mamo; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; Biokemisk teknik; mutagensis; Biochemical technology; xylanase structure; glycoside hydrolase family 10 cloning; Bacillus halodurans; Xylanase; alkaliphiles;

    Abstract : A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. READ MORE

  2. 2. Thermostable Xylanases from Rhodothermus marinus

    University dissertation from Biotechnology, Lund University

    Author : Leif Dahlberg; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; characterization; application; xylanolytic bacteria; thermophile; thermostability; purification; thermostable xylanase; xylosidase; Rhodothermus marinus; xylanase; gene sequence; Biotechnology; Bioteknik;

    Abstract : Popular Abstract in Swedish Populärvetenskaplig sammanfattning Det magnifika skådespelet av erupterande geysrar, varma, rykande källor av skilda slag samt kokande lerpölar är en uppseendeväckande syn. Dessa extrema miljöer av hög temperatur och mycket låga pH-värden verkar långt ifrån livsbejakande. READ MORE

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

    University dissertation from Maher Abou Hachem, Kämnärsvägen 13, E105, 226 46 Lund, Sweden

    Author : Maher Abou-Hachem; Lunds universitet.; Lund University.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium-binding; modular; endoglucanase; thermostable; CBM; xylanase; Biotechnology; Bioteknik;

    Abstract : 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. READ MORE

  4. 4. Trametes versicolor as biodegrader and biocatalyst when using lignocellulose for ethanol production

    University dissertation from Umeå : Umeå Universitet

    Author : Marie Holmgren; Umeå universitet.; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; 5-carbon; 6-carbon; Trametes versicolor; xylose reductase; xylitol dehydrogenase; xylulokinase; phenolics; levulinic acid; HMF; furfural; biodegrader; biocatalyst; pretreatment; xylanase; beta-glucosidase;

    Abstract : Energy consumption has increased rapidly during the last century due to population growth and greater industrialization. Lignocellulosic-based biofuels are being developed as alternatives to fossil fuels. For many years the question of how 5-carbon sugars in biomass are utilized in nature has been a vexed one.

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

    University dissertation from Biotechnology, Lund University

    Author : Eva Nordberg Karlsson; Lunds universitet.; Lund University.; [1999]
    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 : Popular Abstract in Swedish Min avhandling består av sex delarbeten som redovisar olika undersökningar av ett värmestabilt enzym (xylanas). Detta enzym är isolerat från en bakterie (Rhodothermus marinus) som lever i varma källor (vid 55-77 °C) och enzymet förväntas alltså fungera vid dessa temperaturer. READ MORE
