  1. 16. Hydrodynamics considerations in cells systems from ocean flow to perfusion cultivation process

    Författare :Caijuan Zhan; Véronique Chotteau; Jeffrey Chalmers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microorganism; cells; hydrodynamics; turbulence; numerical simulation; CFD; Resonance; Wave bioreactor; ATF; TFF; perfusion; design feeding strategy; Bioteknologi; Biotechnology;

    Sammanfattning : Microorganisms and animal cells are grown surrounded by fluid, which is providing them with nutrients and removing their waste products. In nature and industry processes, cells/microbes can be subject to aggressive environments, such as turbulent flow or shear flow. LÄS MER

  3. 17. Novel Synthetic Biology Tools for Metabolic Engineering of Saccharomyces cerevisiae

    Författare :Siavash Partow; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yeast promoter; MVA pathway; Metabolic engineering; Multi-copy plasmid.; Synthetic biology; S. cerevisiae; MEP pathway;

    Sammanfattning : The most well characterized eukaryote model organism Saccharomyces cerevisiae is not only preferred as a microbial cell factory for synthesis of industrial products, e.g. bioethanol, but this eukaryote host system is also defined as a robust scaffold for commercial production of diverse chemicals e.g. LÄS MER

  4. 18. Fermentation of lignocellulosic material : a study on bacterial contamination and yeast physiology

    Författare :Emma Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; yeast physiology; energy metabolism; Lignocellulosic bioethanol; bacterial contamination;

    Sammanfattning : Progressive depletion of oil and conventional fossil fuels, an increased energy demand and an increased struggle for national energy security has led to the development of alternative biobased fuels, bioethanol being one of them. Bioethanol can be made from many different raw materials, and based upon this are classified as 1st generation and 2nd generation. LÄS MER

  5. 19. Development of Molecular Biology and Bioinformatics Tools : From Hydrogen Evolution to Cell Division in Cyanobacteria

    Författare :Fernando Lopes Pinto; Peter Lindblad; Röbbe Wünschiers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; hydrogen; RNA; bioinformatics; RT-PCR; RACE; transcription; Molecular biology; Molekylärbiologi; Bioinformatics; Bioinformatik; Molecular Biology; Molekylärbiologi;

    Sammanfattning : The use of fossil fuels presents a particularly interesting challenge - our society strongly depends on coal and oil, but we are aware that their use is damaging the environment. Currently, this awareness is gaining momentum, and pressure to evolve towards an energetically cleaner planet is very strong. LÄS MER

  7. 20. Microbial DNA Sequencing in Environmental Studies
