  1. 6. Evolution of Yeast Respiro-Fermentative Lifestyle and the Underlying Mechanisms Behind Aerobic Fermentation

    University dissertation from Lund University, Department of Biology

    Author : Arne Hagman; Lunds universitet.; Lund University.; [2013]
    Keywords : aerobic fermentation; Crabtree effect; respiro-fermentation; ethanol production; yeast; central carbon metabolism; evolution of alternative lifestyles; Biologi; Biology;

    Abstract : Under aerobic conditions, most yeasts such as Kluyveromyces lactis, prefer the respiratory pathway and some, such as Saccharomyces cerevisiae prefer less energy efficient fermentative pathway for their energy metabolism. These two metabolic strategies are also known as Crabtree negative and Crabtree positive respectively, and the evolution of the latter has lately been explained by the “make-accumulate-consume” life strategy.

  2. 7. Elongation factor 2: A key component of the translation machinery in eukaryotes : Properties of yeast elongation factor 2 studied in vivo

    University dissertation from Stockholm : Wenner-Grens institut för experimentell biologi

    Author : Galyna Bartish; Stockholms universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elongation factor 2; yeast; ribosome; phosphorylation; Switch I; site-directed mutagenesis; functional complementation; NATURAL SCIENCES Biology Cell and molecular biology Cell biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Cellbiologi; Cellbiology; cellbiologi;

    Abstract : Synthesis of proteins is performed by the ribosome, a large ribonucleoprotein complex. Apart from the ribosome, numerous protein factors participate in this process. Elongation factor 2 (eEF2) is one of these factors. eEF2 is an essential protein with a mol. READ MORE

  3. 8. Bioreduction of Carbonyl Compounds to Chiral Alcohols by Whole Yeast Cells: Process Optimisation, Strain Design and Non-Conventional Yeast Screening

    University dissertation from Secretary, Applied Microbiology Lund University

    Author : Michael Katz; Lunds universitet.; Lund University.; [2003]
    Keywords : carbonyl; bicyclic diketone; yeast; candida; cerevisiae; reductase; ketone; reduction; whole cell; YMR226c; YDR368w; Microbiology; bacteriology; virology; mycology; Biokemisk teknik; Biochemical technology; mykologi; virologi; Mikrobiologi; bakteriologi; Kemi; Chemistry; Biologi; Biology;

    Abstract : Chiral building blocks are needed for the production of drugs and fine chemicals, which requires the use of several synthetic routes to produce a specific enantiomer of interest. One promising approach to introduce chirality into molecules is the stereo-selective whole cell bioreduction of carbonyl compounds or ketones to the corresponding chiral alcohols. READ MORE

  4. 9. Engineered Yeast as Biocatalyst for Stereoselective reductions of Dicarbonyl Compounds

    University dissertation from Applied Microbiology

    Author : Ted Johanson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2007]
    Keywords : Biologi; Biology; screening; chiral; process optimisation; metabolic engineering; dicarbonyl; biocatalysis; yeast; bioreduction; Biotechnology; Bioteknik;

    Abstract : Chiral building blocks are needed in the chemical and pharmaceutical industries for the production of fine chemicals and pharmaceuticals. The utilisation of microorganisms and enzymes to perform stereoselective reductions of carbonyl compounds is an efficient and widely applied method for the generation of chiral molecules. READ MORE

  5. 10. Silencing and DNA double-strand break repair in budding yeast

    University dissertation from Stockholm : Wenner-Grens institut för experimentell biologi

    Author : Andreas Kegel; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silencing; Reb1; DSB; NHEJ; Nej1; illegitimate recombination; yeast; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi;

    Abstract : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. READ MORE
