  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. Exploring and exploiting plant biomass degradation by Bacteroidetes

    Author : Cathleen Kmezik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polysaccharide utilization locus; plant biomass degradation; carbohydrate esterases; multidomain enzymes; Bacteroidetes; PUL transfer; carbohydrate-active enzymes; xylan;

    Abstract : Bacteroidetes bacteria have evolved to become excellent biomass degraders. They achieved this by applying carbohydrate-active enzymes (CAZymes) and organizing genes connected to the degradation of specific polysaccharides into discrete gene cassettes, so-called polysaccharide utilization loci (PULs).

  5. 3. Structural and functional investigation of underexplored carbohydrate-active enzyme families

    Author : Andrea Seveso; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbohydrate-active enzymes; lytic polysaccharide monooxygenase; plant biomass degradation; copper radical oxidases; carbohydrate esterase; protein structure determination; protein structure prediction;

    Abstract : The known consequences of the current fossil-based economy require a transition towards a bio-based economy. Development of biorefineries in which plant biomass can be utilized as a renewable source of energy and building blocks to produce both commodities and high-value products, is a key step in this transition.

  6. 4. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry

    Author : Arieh Cohen; Avdelningen för arbets- och miljömedicin; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ESI-MS; Polysaccharides; Hydrolysis; Cellulases; Starch Hydrolases; Enzymatic Degradation; Enzymes; Substituent Distribution; Modified Cellulose; Mass Spectrometry; Modified Starch; Analytical chemistry; Analytisk kemi; HPAEC-PAD;

    Abstract : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. READ MORE

  7. 5. Heterologous expression, characterization and applications of carbohydrate active enzymes and binding modules

    Author : Åsa Kallas; Tuula T. Teeri; Edward A. Bayer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Populus; xyloglucan endotransglycosylase; carbohydrate binding modules; endo- 1; 4 -b-xylanase; Escherichia coli; Pichia pastoris; N-glycosylation; fiber analysis; Bioengineering; Bioteknik; Wood fibre and forest products; Träfiber- och virkeslära;

    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
