2. 1. Ethanol Production from Lignocellulosic Materials: Potential of Continuous Cultivation, Immobilisation, and Zygomycetous Fungi

   Author : Ria Millati; Chalmers tekniska högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

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

   Author : Sami Khan; Bioteknik; []
   Keywords : Thermotoga neapolitana; TnBgl1A; Mutagenesis; Flavonoid; Quercetin; Immobilisation; Chaperones;

   Abstract : 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.

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

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

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

   Author : Varuna Chaminda Banduseela; Lars Larsson; Gustavo Nader; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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.

7. 5. Enzyme Printed Fabrics : Bio‐functionalisation of Synthetic Textiles by Digital Inkjet Printing

   Author : Tuser Biswas; Vincent Nierstrasz; Junchun Yu; Tzanko Tzanov; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital printing; inkjet; enzyme; printhead; rheology; immobilisation; piezoelectric; drop-on-demand; resource-efficient textiles; biological ink; lysozyme; tyrosinase; polyphenol oxidase; polyethylene terephthalate; polyester; polyamide-6; 6; nylon; surface modification; plasma; antimicrobial; antibacterial; Textil och mode generell ; Textiles and Fashion General ;

   Abstract : This thesis explores the possibilities of printing enzymes using resource-efficient technologies to promote the binding of other proteins and biomaterials on synthetic textiles. This strategy can be used to develop advanced textiles for applications, for example, in antimicrobial, drug delivery and biosensing. READ MORE
