  1. 16. Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production

    Författare :Raquel Perruca Foncillas; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Biosensors; Flow cytometry; Bioethanol production; Lignocellulosic biomass; Xylose; Strain engineering; Lignocellulosic ethanol; Lignocellulosic inhibitors; Furfural;

    Sammanfattning : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. LÄS MER

  3. 17. 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

  4. 18. Exploring strategies to improve volumetric hydrogen productivities of Caldicellulosiruptor species

    Författare :Thitiwut Vongkampang; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor kronotskyensis; volumetric hydrogen productivity; non-diauxic; acrylic fibres; cell immobilization; chitosan; biofilm; c-di-GMP; cellobiose; xylose; consolidated bioprocessing; heat-treated wheat straw;

    Sammanfattning : Ongoing consumption of fossil-based fuels generates a massive amount of greenhouse gases. This may lead to global warming that is currently threatening human society and wild animal habitats. Hydrogen is an energy carrier with the highest energy content per weight compared to other all fuels and no carbon dioxide is released when combusted. LÄS MER

  5. 19. Ethanol production from lignocellulose using high local cell density yeast cultures. Investigations of flocculating and encapsulated Saccharomyces cerevisiae

    Författare :Johan Westman; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yeast; encapsulation; lignocellulose; ethanol; fermentation; flocculation; inhibitors; tolerance; xylose; co-utilisation; Resource Recovery; Resursåtervinning; Resource Recovery;

    Sammanfattning : Efforts are made to change from 1st to 2nd generation bioethanol production, using lignocellulosics as raw materials rather than using raw materials that alternatively can be used as food sources. An issue with lignocellulosics is that a harsh pretreatment step is required in the process of converting them into fermentable sugars. LÄS MER

  7. 20. Synthesis of Conformationally Restricted Oligosaccharides

    Författare :Michael Wilstermann; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Streptococcus suis; E. coli; neoglycolipid; ganglioside-lactam; xylose; methylene acetal; sialic acid; Conformational Restriction; galabiose; Organic chemistry; Organisk kemi;

    Sammanfattning : Gangliosides are sialic acid-containing glycosphingolipids that often are present in increased amounts on tumor cells. Since the gangliosides are hydroxy-acids, they can form lactones. The lactones have been suspected to be more immunogenic than the open forms, but are in practise poor immunogens due to their ease of hydrolysis. LÄS MER
