  2. 11. Towards sustainable plastics : Microbial production of aromatic and aliphatic building blocks from biobased feedstock and plastic hydrolysate

    Author : Oliver Englund Örn; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell factories; Biobased plastics; Protocatechuic acid; Adipic acid; 4-Hydroxybyratate; 1; 4-Butanediol; PBAT; Enzymatic recycling; Synthetic promoter library;

    Abstract : The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material.

  4. 12. Engineered Alcohol Dehydrogenases for Stereoselective Chemical Transformations

    Author : Thilak Reddy Enugala; Mikael Widersten; Manfred T. Reetz; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alcohol dehydrogenase-A; biocatalysts; protein engineering; enzyme kinetics; sec-alcohols; ketones; stereoselectivity; regioselectivity; substrate selectivity and promiscuity.; Biokemi; Biochemistry;

    Abstract : Enzymes are biomolecules built from amino acids and catalyze the chemical transformations in a cell. Enzymes are by nature stereoselective, biodegradable, environmentally friendly, and can perform catalysis in aqueous solutions and at ambient temperatures. READ MORE

  5. 13. Polyelectrolyte Brush Electrodes for Protein Capture and Release

    Author : Gustav Ferrand-Drake Del Castillo; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pH-responsive interfaces; Polyelectrolyte brushes; protein immobilization; electrochemistry.;

    Abstract : Stimuli-responsive polyelectrolyte brushes switch as a function of pH between a charged and neutral state that affects their electrostatic interactions with other charged molecules like proteins. Adjustment of the pH results in the binding of large quantities of proteins making polyelectrolyte brushes widely used as biointerfaces. READ MORE

  6. 14. 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

  7. 15. 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
