  1. 1. Discovery and applications of family AA9 lytic polysaccharide monooxygenases

    Författare :Monika Tõlgo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lytic polysaccharide monooxygenases; cellulose; xylan; spruce; carbohydrate active enzymes; LPMO; lignocellulolytic enzyme cocktails; lignocellulose; polysaccharides; AA9; cellulose nanocrystals; thermophilic fungi;

    Sammanfattning : Auxililary activity family 9 lytic polysaccharide monooxygenases (abbreviated as AA9s or LPMO9s) are fungal mono-copper enzymes capable of oxidatively cleaving various plant cell wall oligo- and/or polysaccharides. LPMO9s are key components of lignocellulolytic enzyme cocktails used in today’s biorefineries to break down biomass into fermentable sugars. LÄS MER

  3. 2. Enzymes for selective decoupling of woody biomass: From fundamentals to industrial potential

    Författare :Jenny Arnling Bååth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulose; glucuronoyl esterase; polysaccharide acetylation; carbohydrate esterase family 15; woody biomass; materials biorefinery; enzyme accessibility; lignin-carbohydrate bonds; mannanase; galactoglucomannan;

    Sammanfattning : The need for an economy based on renewable materials has resulted in growing interest in the use of woody biomass in a wider field of application. However, the chemical complexity of lignocellulose and the dense structure of wood pose challenges in its processing. LÄS MER

  4. 3. Structuring plant cell materials using pre-treatments. Effects on texture and carotenoid accessibility

    Författare :Evelina Tibäck; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PG; degree of methoxylation; texture; carrot; Bostwick consistency index; microstructure; in vitro carotenoid accessibility; PME; tomato; carotenoid content;

    Sammanfattning : A high consumption of fruits and vegetables is considered beneficial and to support good health. To promote higher fruit and vegetable intake, attractive and nutritious fruit- and vegetable-based ready-to-eat products should be available on the market. A key property of an attractive food product is a palatable texture. LÄS MER

  5. 4. EVALUATION OF BIOLOGICAL STRATEGIES TO ENHANCE HYDROLYSIS DURING ANAEROBIC DIGESTION OF COMPLEX WASTE

    Författare :Dores Cirne; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; kontroll av utsläpp; Biotechnology; bioaugmentation; enzyme addition; Environmental technology; pollution control; FISH; cellulose; inhibition; lipids; Clostridium lundense; hydrolysis; complex substrate; Anaerobic digestion; renewable energy; Bioteknik; LCFA;

    Sammanfattning : Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the huge amounts of these types of waste generated annually.

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

    Författare :Mattias Persson; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
