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

   University dissertation from University of Borås: School of Engineering ; Chalmers University of Technology: Department of Chemical and Biological Engineering

   Author : Johan Westman; Högskolan i Borås.; [2014]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Recovery; Resursåtervinning; yeast; encapsulation; lignocellulose; ethanol; fermentation; flocculation; inhibitors; tolerance; xylose; co-utilisation; Resource Recovery; Yeast;

   Abstract : 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. READ MORE

4. 2. Catabolism of Pyrimidines in Yeast

   University dissertation from Department of Biology, Lund University

   Author : Anna Rasmussen; Lund University.; Lunds universitet.; [2014]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pyrimidine degradation; catabolism of pyrimidines; nucleic acid precursors; yeast; Lachancea kluyveri; URC pathway;

   Abstract : Pyrimidines are important precursors for nucleic acids, and constantly synthesized and degraded in the cell to maintain a balanced supply. Many microoganisms can also extract the nitrogens from the pyrimidine ring, and use them as a nitrogen source when “preferred” sources are absent. READ MORE

5. 3. RAP1 at the Yeast Telomere

   University dissertation from Johan Wahlin, Dep. of Cell and Organism Biology, Sölvegatan 29, 223 62 Lund, Sweden

   Author : Johan Wahlin; Lund University.; Lunds universitet.; [2002]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; DNA-binding; Saccharomyces; yeast; telomeric repeat; telomere; RAP1; repressor activator protein 1; Genetics; cytogenetics; Genetik;

   Abstract : Telomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. READ MORE

6. 4. Importance of the Clr2 protein in heterochromatin formation in the fission yeast Schizosaccharomyces pombe

   University dissertation from Uppsala : Uppsala universitet

   Author : Daniel Steinhauf; Uppsala universitet.; [2017]
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clr2; Yeast; Heterochromatin; Fission yeast; Schizosaccharomyces pombe; Biokemi; Biochemistry;

   Abstract : Epigenetics is an area of biology that studies heritable changes in gene ex- pression without any change in the DNA sequence. The most studied epige- netic mechanisms are DNA methylation, RNA interference and histone mod- ifications. READ MORE

7. 5. Chromosome synapsis and recombination in yeast meiosis

   University dissertation from Stockholm : Institutionen för molekylärbiologi och funktionsgenomik

   Author : Hasanuzzaman Bhuiyan; Stockholms universitet.; [2004]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; meiosis; recombination; synapsis; yeast; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

   Abstract : Meiosis is a cell division process that produces haploid gametes from diploid cells. Several important meiotic events take place during prophase of meiosis I, most important being homologous chromosome pairing, meiotic recombination and formation of the synaptonemal complex (SC).
