  1. 11. 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

  3. 12. Ethanol Production from Cellulosic Biomass by Encapsulated Saccharomyces cerevisiae

    Författare :Farid Talebnia; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; encapsulated cells; ethanol; s.cerevisiae; dilute-acid hydrolyzate; in situ detoxification; furfural; orange peels; experimental design; immobilization; limonene;

    Sammanfattning : Unstable oil markets with rising environmental concerns have revived widespread interest in production of fuel ethanol from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cheap ethanol production. However, due to recalcitrant structure of these materials, pretreatment is a prerequisite. LÄS MER

  4. 13. Carbohydrate-specific, boronate-containing copolymers: from sugar-sensing to cell adhesion

    Författare :Marina Kuzimenkova; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface grafting; chemisorption; boronic acid; carbohydrates; affinity; chromatography; smart polymers; biomimetics; hydrogels; molecular recognition; diffusion; sugar-sensing; cell adhesion;

    Sammanfattning : Carbohydrates play a major role in many cell recognition events and metabolic pathways of living organisms. Synthetic carbohydrate receptors are of great interest for the chemical design of sugar sensors, materials for cell separation, cell immobilization, drug delivery and other biomedical/biotechnological applications.

  5. 14. QCM-D – with focus on biosensing in biomolecular and cellular systems

    Författare :Erik Nilebäck; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; QCM-D; biomolecular interactions; cell-surface interaction; glycosaminoglycans; viscoelasticity; cell morphology; Quartz crystal microbalance with dissipation monitoring; surface chemistry; protein conformation;

    Sammanfattning : The high degree of complexity in biological systems is being investigated in greater and greater detail by increasingly sophisticated sensing approaches. The quartz crystal microbalance with dissipation monitoring (QCM-D) technique stands out in this context, by probing the viscoelastic properties at interfaces. LÄS MER

  7. 15. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

    Författare :Tarek Dishisha; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

    Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER
