The indiscriminate use of pesticide could potentially impact on the long-term food production, environmental and human health in the delta. READ MORE

  2. 12. Lipases as Biocatalysts in Organic Media. Influence of Enzyme Preparation and Reaction Conditions on Activity and Selectivity

    University dissertation from Mattias Persson Sölvegatan 39, kemicentrum, Lunds universitet

    Author : Mattias Persson; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biochemical technology; Bioteknik; Biotechnology; water activity; temperature; enantioselectivity; immobilisation; organic solvents; lyophilisation; Lipases; Accurel EP-100; Biokemisk teknik; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : The discovery that enzymes can function in organic solvents has broadened the scope of biocatalysis, making enzymes highly useful tools for organic chemists. The widespread use of enzymes as catalysts in organic solvents has, however, been limited by the low activity obtained for enzymes in organic solvents compared to aqueous solutions. READ MORE
