  2. 1. Pretreatment and enzymatic saccharification of lignocellulose : formation and effects of pseudolignin

    Author : Monica Normark; Leif Jönsson; Sandra Winestrand; Torbjörn Lestander; Wilfred Vermerris; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pretreatment; enzymatic saccharification; ionic liquid; torrefaction; pseudolignin; Analytical Chemistry; analytisk kemi;

    Abstract : Production of advanced biofuels, green chemicals, and bio-based materials from renewable lignocellulosic biomass would contribute to decreased dependence on fossil resources and to sustainable development. The overall aim of the investigations was to explore how preprocessing and pretreatment technologies affected the chemical composition of cellulosic materials and their susceptibility to enzymatic saccharification, which is one of the major routes for biorefining of lignocellulose.

    Abstract : Methods have been studied for the production of chiral alcohols, which are of importance in organic synthesis of pharmaceuticals, agro-chemicals and fragrances, etc., through the enzymatic or microbial reduction of ketones. READ MORE

  5. 3. Modeling of enzyme kinetics on polymeric substrates by simulation : Enzymatic hydrolysis of cellulose

    Author : Veljo Sild; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Biopolymers are an essential constituent of living matter. To develop new products and processes based on enzyme production and modification and hydrolysis of biopolymers, enzymes with well understood mechanism are required. It is impossible to derive a universal analytical model for every particular enzyme/polymer system. READ MORE

  7. 5. Aldolases for Enzymatic Carboligation : Directed Evolution and Enzyme Structure-Function Relationship Studies

    Author : Huan Ma; Mikael Widersten; Wolf-Dieter Fessner; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aldolase; 2-deoxyribose-5-phosphate aldolase; fructose-6-phosphate aldolase; directed evolution; enzyme dynamics; Biokemi; Biochemistry;

    Abstract : The research summarized in this thesis focuses on directed evolution and enzyme mechanism studies of two aldolases: 2-deoxyribose-5-phosphate aldolase (DERA) and fructose-6-phosphate aldolase (FSA).Aldolases are nature’s own catalysts for one of the most fundamental reactions in organic chemistry: the formation of new carbon-carbon bonds.
