  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

    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. Suberin based polyesters

    Author : Ann Olsson; Monica Ek; Mats Johansson; Margaretha Söderqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : In the wish to replace oil-based chemicals and materials with such based on biodegradable and renewable resources, this work has been performed. In a biorefinary concept, waste birch bark from paper pulp mills and timber production has been evaluated as a potential source for polyesters. READ MORE
