2. 1. 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. 2. Chemoenzymatic synthesis of anionic alkyl glycosides

   Author : NGOC NGO; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkyl glycosides; laccase; TEMPO; oxidation; cyclodextrin glucanotransferases;

   Abstract : Growing concerns for environmental issues and product safety for users have shifted research interests towards the use of renewable resources and climate-neutral processes. The enzymatic approach having high selectivity under mild reaction conditions is promising, and the nature-originating products are well accepted. READ MORE

5. 3. Enzymatic Synthesis of Alkyl Glycosides. New Applications for Glycoside Hydrolases

   Author : David Svensson; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CGTase; cyclodextrin glycosyltransferase; alkyl glycoside; enzyme stabliity; enzymatic synthesis; enzyme immobilisation; surfactant; glycosylation;

   Abstract : The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. READ MORE

6. 4. Lewis acid promoted endocyclic cleavage of glycosides and related acetals

   Author : Roger Olsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; halichomycin; allylation; carbene; hydrogen bond; organozinc; organotitanium; furanosides; organoaluminium; pyranosides; glycosides; stereoselective; endocyclic cleavage; nucleophilic ring opening; ab initio; Organic chemistry; Organisk kemi;

   Abstract : This thesis is a summary of five papers concerning endocyclic cleavage of glycosides and related acetals. Simple lactol ethers undergo endocyclic cleavage to give acyclic chain extended products on treatment with organoaluminium and organotitanium reagents. READ MORE

7. 5. Novel Retaining Glycoside Hydrolases : Potential candidates for transglycosylation and hydrolysis

   Author : Zubaida Gulshan Kazi; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glycoside hydrolase; transglucosylation; alkyl glycoside; cyclodextrin glucanotransferase; Rhodothermus marinus; xylanases; hydrolysis; beta-glucosidases;

   Abstract : Our society is moving towards renewable resources, where biomass, rich incarbohydrates, is producing chemicals and fuel. However, there are severallimitations when it comes to valorisation of the carbohydrates from renewablebiomass. READ MORE
