  1. 1. Laccases and Oxalate-Degrading Enzymes Heterologous Expression and Novel Applications in Lignocellulose Processing

    Författare :Pierre Cassland; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; virology; mycology; Mikrobiologi; virologi; mykologi; bacteriology; Microbiology; Lignocellulose Processing; Heterologous expression; Laccases; Oxalate-Degrading Enzymes; bakteriologi;

    Sammanfattning : Lignocellulose constitutes a vast renewable resource for the production of, for example, paper and bioethanol. The potential of using laccase and oxalate-degrading enzymes in novel applications for the processing of lignocellulose was investigated in this work. LÄS MER

  3. 2. Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings

    Författare :Benny Palmqvist; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulose; Bioethanol; High solid loadings; Biomass rheology; Enzymatic hydrolysis; Simultaneous Saccharification and co-Fermentation;

    Sammanfattning : Fuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. LÄS MER

  4. 3. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose

    Författare :Erfan Oliaei; Lars Berglund; Tom S. C. Lindström; Fredrik Berthold; ‪Maria Soledad Peresin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.

  5. 4. Process development for platform chemical production from agricultural and forestry residues

    Författare :David Nickel; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Biorefinery; pretreatment; lignocellulose; multi-feed SSCF; preadaptation; multi-scale variability analysis; platform chemicals; lactic acid; logging residues; mixed feedstocks; ethanol;

    Sammanfattning : As part of a bio-based economy, biorefineries are envisaged to sustainably produce platform chemicals via biochemical conversion of agricultural and forestry residues. However, supply risks, the recalcitrance of lignocellulosic biomass, and inhibitor formation during pre­treatment impair the economic feasibility of such biorefineries. LÄS MER

  7. 5. 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
