  2. 1. Hydrolases as Catalysts for Green Chemistry and Industrial Applications - Esterase, Lipase and Phytase

    Author : Yasser Gaber; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPLC-EAT; sustainable environment; mutation; metallo-enzyme; phytate; b-propeller; biodegraqdable; metrics; green chemistry; Novozym 435; CalB; solvent-free; kinetic resolution; Biocatalysis; rational design; PLE; esterase; clopidogrel; enantioselectivity;

    Abstract : The use of enzymes in industrial applications has been recognised for providing clean processes with minimal impact on the environment. This thesis presents studies on engineering of enzymes and enzyme-based processes in the light of green chemistry and environmental sustainability, and focuses on three hydrolases: esterase, lipase and phytase.

  5. 3. Chemo-enzymatic epoxidation: Activity and stability of Candida antarctica lipase B

    Author : Ulrika Törnvall; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Growing concerns about climate change and depleting fossil feedstocks are driving a shift within the chemical industry from energy-intensive processes to more environmentally sound and sustainable processing using renewable feedstocks. One such process is the utilization of lipases for the chemo-enzymatic epoxidation of vegetable oils and fatty acids. READ MORE

  6. 4. Chemo-Enzymatic Epoxidation of Unsaturated Fatty Acids

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; solvent-free process.; Candida antarctica lipase B esterification; chemo-enzymatic epoxidation; Unsaturated fatty acids; epoxides;

    Abstract : Epoxy fatty acids are useful molecules and find a number of applications e.g. as PVC plasticisers and stabilisers, additives in polyurethane production, reactive diluents in paints, corrosion protection agents, etc. READ MORE

  7. 5. Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

    Author : Amin Bornadel; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Abstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. READ MORE
