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

   Författare :Andrea Seveso; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 3. Strategies for the Discovery of Carbohydrate-Active Enzymes from Environmental Bacteria

   Författare :Johan Larsbrink; Vincent Bulone; Harry Brumer; Birte Svensson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CAZyme discovery; xyloglucan; polysaccharide-utilisation locus; microbiota; α-xylosidase; GH31; transglucosidase; human gut; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

   Sammanfattning : The focus of this thesis is a comparative study of approaches in discovery of carbohydrate-active enzymes (CAZymes). CAZymes synthesise, bind to, and degrade all the multitude of carbohydrates found in nature. LÄS MER

5. 4. Exploring and exploiting plant biomass degradation by Bacteroidetes

   Författare :Cathleen Kmezik; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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).

7. 5. Discovery and applications of family AA9 lytic polysaccharide monooxygenases

   Författare :Monika Tõlgo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lytic polysaccharide monooxygenases; cellulose; xylan; spruce; carbohydrate active enzymes; LPMO; lignocellulolytic enzyme cocktails; lignocellulose; polysaccharides; AA9; cellulose nanocrystals; thermophilic fungi;

   Sammanfattning : Auxililary activity family 9 lytic polysaccharide monooxygenases (abbreviated as AA9s or LPMO9s) are fungal mono-copper enzymes capable of oxidatively cleaving various plant cell wall oligo- and/or polysaccharides. LPMO9s are key components of lignocellulolytic enzyme cocktails used in today’s biorefineries to break down biomass into fermentable sugars. LÄS MER
