    Författare :Ria Millati; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuous cultivation; galactose; Rhizopus; xylose; Rhizomucor; S cerevisiae; Mucor; M indicus; glucose; immobilisation; detoxification; arabinose; mannose; overliming; ethanol; dilute-acid hydrolysate;

    Sammanfattning : This thesis deals with the production of bio-ethanol, a sustainable alternative to fossil fuels, from dilute-acid lignocellulosic hydrolysate in a continuous immobilised cell system and fermentation of the hydrolysate by a zygomycete organism, M. indicus. LÄS MER

  2. 2. Molecular development of a thermostable β-glucosidase for modification of natural products

    Författare :Sami Khan; Lund University.; Lunds universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermotoga neapolitana; TnBgl1A; Mutagenesis; Flavonoid; Quercetin; Immobilisation; Chaperones;

    Sammanfattning : The gene encoding a β-glucosidase originating from the extreme thermophile Thermotoga neopolitana has been cloned and expressed in Escherichia coli. The aim was to produce a thermostable enzyme that could be used to remove sugar residues from glucosylated natural products classified as flavonoids by applying a method combining extraction in hot pressurized water with enzymatic hydrolysis.

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

    Detta är en avhandling från Mattias Persson Sölvegatan 39, kemicentrum, Lunds universitet

    Författare :Mattias Persson; Lund University.; Lunds universitet.; [2001]
    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

  4. 4. Properties and Applications of Temperature Sensitive Gels

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Matz Andersson; [1996]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Swelling kinetics; Poly N-isopropylacrylamide gel; NiPAAm; Immobilisation; Hydrogels; Gel extraction; Flory-Huggins; Diffusion; Controlled Release; Kemiteknik och kemisk teknologi;

    Sammanfattning : The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. LÄS MER

  5. 5. Molecular And Cellular Networks in Critical Illness Associated Muscle Weakness Skeletal Muscle Proteostasis in the Intensive Care Unit

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Varuna Chaminda Banduseela; Uppsala universitet.; [2012]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chaperones; autophagy; intensive care unit; heat shock proteins; protein synthesis; proteostasis; ER stress; gene expression; sepsis; neuromuscular blockers; corticosteroids; immobilisation; mechanical ventilation; Molekylär cellbiologi; Molecular Cellbiology; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Critical illness associated muscle weakness and muscle dysfunction in intensive care unit (ICU) patients lead to severe morbidity and mortality as well as significant adverse effect on quality of life. Immobilization, mechanical ventilation, neuromuscular blocking agents, corticosteroids, and sepsis have been implicated as important risk factors, but the underlying molecular and cellular mechanisms remain unclear.
