  1. 21. Evaluating Sugar Signaling during Xylose Oxidation in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Viktor Persson; [2020]
    Keywords : Saccharomyces cerevisiae; yeast; xylose oxidation; sugar signaling; biosensor; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : The sugar signaling state of cells oxidizing xylose was investigated through the chromosomal integration of the Weimberg pathway into previously established biosensor strains capable of monitoring the Snf3p/Rgt2p, SNF1/Mig1p, and cAMP/PKA pathways through the expression of HXT1, SUC2, and TPS1, respectively. Ultimately, two new strains were successfully developed containing both the Weimberg pathway and a biosensor for either HXT1 (TMB CB 112) or TPS1 (TMB CB 117). READ MORE

  3. 22. Development of bicistronic transcription and translation unit (TNT) for reliable expression of heterologous genes in Synechocystis PCC 6803

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Tereza Hubackova; [2020]
    Keywords : bicistronic design; BCD; Synechocystis PCC 6803; gene regulation; metabolic engineering;

    Abstract : Rational metabolic engineering requires tools for precise control of heterologous gene expression at predictable levels. Especially, regulatory genetic elements, such as promoters and ribosome binding sites, that can provide strong and reliable expression, are needed. READ MORE

  4. 23. Evolving Text Classifier Using Genetic Programming

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Hoang Ngo; Ema Eminagic; [2020]
    Keywords : genetic programming; evolutionary algorithm; evolutionary computation; text classification; n-grams; natural language processing; Technology and Engineering;

    Abstract : Text classification is one of the main tasks within the field of natural language processing, which has been growing significantly during the last decade with applications in different industries. Despite different approaches to text classification showing good results, such as Machine Learning and Deep Learning, their shortcomings give substance to the need for further research on other approaches.

  5. 24. Assessment of the Fluorescent Activities of Different Fluorescent Proteins for Potential Use as Biosensors in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Johan Davidsson; [2020]
    Keywords : Fluorescent proteins; Saccharomyces cerevisiae; Flow cytometry; CRISPR Cas9; Biosensors; Applied microbiology; Tillämpad mikrobiologi; Technology and Engineering;

    Abstract : Development of genetically modified microorganisms such as Saccharomyces cerevisiae for use as microbial cell factories to produce fine and bulk chemicals has lately proceeded very rapidly, much thanks to new gene editing methods based on a CRISPR/Cas9 system adapted from bacteria which increases the rate of genetic engineering. However, development of methods which enable fast and simple screening of the best performing strains with specific sought-after characteristics is not advancing at the same pace. READ MORE

  6. 25. Fast retuning of superconducting radiofrequency accelerating cavities in the European Spallation Source linear accelerator.

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofia Johannesson; [2020]
    Keywords : Accelerator; retuning; ESS; Technology and Engineering;

    Abstract : The aim of the degree project is to continue the work of PhD student YuanShuai Qin on creating a fast retuning of the ESS accelerator lattice in the event of an accelerating cavity being offline. The main goal of the project was evaluating and improving the retuning routine created by YuanShuai Qin. READ MORE
