  1. 16. Functional studies of the TDH and GPD gene-products in the glycolytic flux and glycerol metabolism of Saccharomyces cerevisiae

    Författare :Hadi Valadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Growth rate; GPD; Sacchromyces cerevisiae; Glyceol; NADH; Anaerobiosis; TDH; Redox; Glycolysis;

    Sammanfattning : This thesis focuses on the physiology and control of the glycolysis and glycerol metabolism in the yeast Sacchromyces cerevisiae. The study is based on the relation ship between the first two reactions around the branch-point of the upper and lower part of glycolysis and the glycerol pathway. LÄS MER

  3. 17. 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.

  4. 18. Conversion of lignocellulose and crude glycerol to lipids by oleaginous yeasts - physiology and diversity

    Författare :Mikolaj Chmielarz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Oleaginous yeasts are organisms capable of accumulating lipids. Some of them can grow on various substrates considered to be too toxic for many other microorganisms. Crude glycerol (CG) and hemicellulose hydrolysate (HH) are two examples of such substrates. LÄS MER

  5. 19. Insights into genomics and gene expression of oleaginous yeasts of the genus Rhodoturula

    Författare :Giselle De La Caridad Martín Hernández; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Rhodotorula glutinis cluster includes oleaginous yeast species with high biotechnological potential as cell factories for lipid, carotenoid, and oleochemical production. They can grow on various low-cost residues, such as lignocellulose and crude glycerol. LÄS MER

  7. 20. Toxicity and biological impact of metal and metal oxide nanoparticles : Focus on the vascular toxicity of ultra-small titanium dioxide nanoparticles

    Författare :Narges Bayat; Susana Cristobal; Janeck James Scott-Fordsmand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanoparticles; Nanotoxicology; Ultra-small nanoparticles; Biochemistry; biokemi;

    Sammanfattning : The application of nanoparticles (NPs) in different technologies has led to tremendous advancement in those fields.  Moreover, there is growing interest in application of ultra-small NPs (USNPs) at 1-3 nm due to their distinct molecule like features. Parallel to these promises, there is a growing concern regarding their safety. LÄS MER
