2. 21. Transglycosylation by Glycoside Hydrolases - Production and modification of alkyl glycosides

   Author : Pontus Lundemo; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Glycoside hydrolases; Cyclodextrin glucanotransferases; β-glucosidases; Alkyl glycosides; Thermotoga neapolitana; Organic reaction media;

   Abstract : To enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. READ MORE

4. 22. Exploiting enzyme promiscuity for rational design

   Author : Cecilia Branneby; Karl Hult; Alex Zaks; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Candida antarctica lipase B; alanine racemase; substrate specificity; reaction specificity; enzyme catalytic promiscuity; Biokemi; Biochemistry; Biokemi;

   Abstract : Enzymes are today well recognized in various industrial applications, being an important component in detergents, and catalysts in the production of agrochemicals, foods, pharmaceuticals, and fine chemicals. Their large use is mainly due to their high selectivity and environmental advantage, compared to traditional catalysts. READ MORE

5. 23. Multidimensional engineering for the production of fatty acid derivatives in Saccharomyces cerevisiae

   Author : Yating Hu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein engineering; Saccharomyces cerevisiae; fatty acid derivatives; metabolic engineering; tolerance; transporter;

   Abstract : Saccharomyces cerevisiae , also known as budding yeast, has been important for human society since ancient time due to its use during bread making and beer brewing, but it has also made important contribution to scientific studies as model eukaryote. The ease of genetic modification and the robustness and tolerance towards harsh conditions have established yeast as one of the most popular chassis in industrial-scale production of various compounds.

6. 24. Influencing anaerobic digestion early stage processes for increased biomethane production from different substrate components

   Author : Anna Odnell; Bettina Muller; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Finding alternatives to petroleum-based energy sources is of interest since it could reduce the emissions of net carbon dioxide to the atmosphere by increasing the usage of renewable energy sources. To do so improvements are needed in the renewable energy production sector. READ MORE

7. 25. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood

   Author : Charlotte Tengborg; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; recirculation of process streams; detoxification; inhibition; hydrolysis conditions; enzymatic hydrolysis; Ethanol production; steam pretreatment; softwood; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

   Abstract : The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. READ MORE
