  1. 26. Fermentation of undetoxified dilute acid lignocellulose hydrolysate for fuel ethanol production

    Författare :Tomas Brandberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrolysate; lignocellulose; Saccharomyces cerevisiae; nitrogen limitation; microaerobic conditions; cell recirculation; continuous fermentation; Mucor indicus; ethanol; cell retention;

    Sammanfattning : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. LÄS MER

  3. 27. Effects of ethanol on the expression of immediate-early genes in nerve cells

    Författare :Wei-Qun Ding; Institutionen för laboratoriemedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuroadaptation; the central nervous system; AP-1; junD; junB; c-jun; fosB; c-fos; neuroblastoma SH-SY5Y; ethanol; immediate-early genes; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Immediate-early genes of the fos and jun families encode proteins that dimerize to form a complex of activator protein 1 and regulate the expression of a number of genes in the nervous system. Ethanol has previously been shown to induce alterations in expression of fos and jun genes in the brain. LÄS MER

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

    Författare :Ria Millati; Chalmers tekniska högskola; []
    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

  5. 29. On cholinergic mechanisms involved in ethanol reinforcement. A behavioral and neurochemical study in rodents

    Författare :Anna Larsson; Göteborgs universitet; []
    Nyckelord :Acetylcholine; Dopamine; Ethanol; Locomotor activity; Microdialysis; Nicotine; Nicotinic acetylcholine receptors; Rodents; Reward;

    Sammanfattning : Alcohol (ethanol) and smoking (nicotine) are commonly co-abused in human beings. Drugs of abuse interact with the brain mesolimbic dopamine system, an important part of the brain reward system. These dopaminergic neurons originate in the ventral tegmental area and project to e.g. LÄS MER

  7. 30. Energy efficiency measures in a kraft pulp mill converted to a biorefinery producing ethanol

    Författare :Rickard Fornell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; energy efficiency; process integration; biofuels; kraft pulp mill; ethanol;

    Sammanfattning : Large scale, sustainable production of ethanol biofuel will most likely require commercialization of processes using lignocellulosic raw materials. To date no commercial plant exists however, due to the difficulties in reaching production costs that can compete with 1st generation ethanol and fossil fuels. LÄS MER
