  1. 16. Improving Stress Tolerance in Industrial Saccharomyces cerevisiae Strains for Ethanol Production from Lignocellulosic Biomass

    Författare :Valeria Wallace; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; lignocellulose; ethanol; inhibitors; temperature; stress tolerance;

    Sammanfattning : The present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors.

  3. 17. Technological innovation and industrial evolution : the emergence of industrial networks

    Författare :Anders Lundgren; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Technological innovation is one of the most important sources of corporate and industrial growth. Yet, we know notably little of the relationship between innovation and economic change. LÄS MER

  4. 18. Appraisal of strategies to improve thermophilic hydrogen production exploiting Caldicellulosiruptor species

    Författare :Eoin Byrne; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Caldicellulosiruptor; Hydrogen; osmotolerance; Biorefinery; Osmolarity; Adaptive laboratory evolution; Co-culture; Volumetric productivity; Methane; Polyhydroxybutyrate; Coprothermobacter proteolyticus;

    Sammanfattning : The transition from a fossil to a bio-based economy is of vital importance to stem the effects of ongoing climate change.This bio-based economy will necessitate the production of both biofuels and chemical compounds from biologicalsources. LÄS MER

  5. 19. On bacterial formats in protein library technology

    Författare :Per-Åke Löfdahl; Per-Åke Nygren; Mikael Widersten; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody molecule; β-lactamase; combinatorial library; green fluorescent protein GFP ; protein engineering; protein fragment complementation assay PCA ; selection; TEVprotease; TNF-α; Bioengineering; Bioteknik; Enzyme engineering; Enzymteknik;

    Sammanfattning : Millions of years of evolution have resulted in an immense number of different proteins, which participate in virtually every process within cells and thus are of utmost importance for allknown forms of life. In addition, there are several examples of natural proteins which have found use in applications outside their natural environment, such as the use of enzymes infood industry and washing powders or the use of antibodies in diagnostic, bioseparation or therapeutic applications.

  7. 20. Ethanol from lignocellulose : physiological effects of inhibitors and fermentation strategies

    Författare :Mohammad J Taherzadeh; Chalmers Univ of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetic acid; Agents; Cellulose; Enzyme inhibition; Feedback control; Fermentation; Hydrolysis; Metabolites; pH; Physiology; Wood; Yeast; Dilute acid hydrolyzate; Inhibitors; Lignocellulose; Physiological effects; Saccharomyces cerevisiae; Ethanol;

    Sammanfattning : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). LÄS MER
