  2. 1. 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

  4. 2. Biorefining of lignocellulose : Detoxification of inhibitory hydrolysates and potential utilization of residual streams for production of enzymes

    Author : Adnan Cavka; Leif J. Jönsson; John N. Saddler; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose.

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

    Author : Marie Holmgren; Anita Sellstedt; Mohammad Taherzadeh; Umeå universitet; []
    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.

    Abstract : Wood and wood products are of great economical and environmental importance, both in Sweden and globally. Biotechnology can be used both for achieving raw material of improved quality and for industrial processes such as biobleaching. READ MORE

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

    Author : Maher Abou-Hachem; Bioteknik; []
    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
