   Abstract : Biocatalysis is the branch of science at the intersection between chemistry and biology and specifcally dedicated to the application of natural evolvable catalysts, i.e. enzymes, in human-designed chemical processes. Among the array of promising biocatalysts, transaminases (EC 2. READ MORE

4. 2. Rational engineering of esterases for improved amidase specificity in amide synthesis and hydrolysis

   Author : Peter Hendil-Forssell; Mats Martinelle; Romas J. Kazlauskas; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Amidase; Biocatalysis; Enzyme; Esterase; Enzyme engineering; Lipase; Substrate specificity; Bioteknologi; Biotechnology;

   Abstract : Biocatalysis is an ever evolving field that uses enzymes or microorganisms for chemical synthesis. By utilizing enzymes that generally have evolved for specific reactions under mild conditions and temperatures, biocatalysis can be a more environmentally friendly option compared to traditional chemistry.

5. 3. Enzyme catalysis towards bio-based UV-curable buildingblocks

   Author : Maja Finnveden; Mats Martinelle; Katja Loos; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Enzyme; Enzymatic Polymerizations; Biocatalysis; Lipase; CalB; MsAcT; Substrate specificity; Selectivity; Polymer Chemistry; UV-curring; Bioteknologi; Biotechnology;

   Abstract : Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can be done to develop more environmental methods for producing them. READ MORE

6. 4. Immobilization of Enzymes in Mesoporous Silica for the Conversion of CO2 to Methanol

   Author : Milene Zezzi Do Valle Gomes; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biocatalysis; mesoporous silica; nitrogen sorption analysis; CO2 reduction; Immobilization;

   Abstract : Enzymes are powerful biomolecules able to catalyse chemical reactions under mild conditions and with high selectivity. However, their use in industrial processes is many times hindered due to their high costs and low stability. To overcome these problems the enzymes can be immobilized in an inert support material.
