  2. 1. 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

  4. 2. Stable chlorine isotope analysis of chlorinated acetic acids

    Author : Milena Edith Ivansson; Henry Holmstrand; Örjan Gustafsson; Teresia Svensson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stable chlorine isotope analysis; chlorinated acetic acids; compound-specific isotope analysis;

    Abstract : Chlorinated acetic acids (CAAs) constitute a group of polar organic compounds that are ubiquitous in the environment. Their environmental occurrence has been extensively studied but their sources are still not well constrained. READ MORE

  5. 3. Atmospheric Corrosion of Historic Lead Organ Pipes

    Author : Annika Niklasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; conservation strategies; formiate; historical organs; organ pipe corrosion; lead; oak wood; formic acid; acetic acid; acetate;

    Abstract : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. READ MORE

  6. 4. Atmospheric Corrosion of Lead. The Influence of Organic acid Vapours and Inorganic Air Pollutants. A contribution Towards Understanding the Environmental Degradation of Historic Organ Pipes

    Author : Annika Niklasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organ pipe; formic acid; Atmospheric corrosion; lead formate; lead acetate; NaCl; lead; acetic acid;

    Abstract : This thesis presents different perspectives on the atmospheric corrosion of lead, aiming at a better understanding of the environmental degradation of historical organ pipes. Corroded organ pipes from the field have been analyzed and the environment inside the organ wind system has been mapped. READ MORE

  7. 5. 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
