  2. 1. Acid Tolerance of Streptococcus Mutans Biofilms

    Author : Jessica Neilands; Malmö högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Abstract : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. READ MORE

  4. 2. Biobased Adipic Acid - Challenges in Establishing a Cell Factory

    Author : Emma Skoog; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 2-hexenedioic acid; enzyme engineering; 6-aminohex-2-enoic acid; S. cerevisiae; adipic acid pathway via lysine; cell factory; C. viswanathii; lignocellulose; biorefinery; tolerance; in silico docking; adipic acid;

    Abstract : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. READ MORE

  5. 3. CRISPRi/a for investigating yeast tolerance to inhibitors in lignocellulosic hydrolysates

    Author : Ibai Lenitz Etxaburu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic hydrolysates; ChIP-exo; Screening; Biosensor; Formic acid; Competitive growth assay; Yeast; Tolerance; CRISPRi a; Acetic acid;

    Abstract : Saccharomyces cerevisiae has immense potential as a cell factory in various biotechnological processes where biomass from agricultural industry residues is used as feedstock. Nonetheless, the inhibitors released during the pretreatment of the biomass makes lignocellulosic hydrolysates a challenging substrate for microorganisms. READ MORE

  6. 4. Exploring Saccharomyces cerevisiae’s responses to acetic acid and other inhibitors found in lignocellulosic hydrolysates

    Author : Maurizio Mormino; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; acetic acid biosensor; formic acid; CRISPRi screening; acetic acid; Saccharomyces cerevisiae; lignocellulosic inhibitor tolerance; differential gene expression;

    Abstract : The limited tolerance of the budding yeast Saccharomyces cerevisiae to lignocellulosic hydrolysate inhibitors is a key challenge to its use in biorefinery cell factories. Considerable resources have been invested in the isolation of yeast strains with better tolerance towards the inhibitors released during lignocellulose hydrolysis, such as acetic acid. READ MORE

  7. 5. Modelling of tolerance and rebound in normal and diseased rats

    Author : Christine Ahlström; Göteborgs universitet; []
    Keywords : feedback modelling; tolerance; rebound; pharmacokinetics; pharmacodynamics; dyslipidaemia; nicotinic acid; non-esterified fatty acids;

    Abstract : The development of rebound and tolerance is an important consideration when optimizing medical therapy, both with respect to drug dosing and adverse effects. By using quantitative approaches to study these processes, potential risks can be minimized. READ MORE
