  2. 1. Evaluation of biosensors and flow cytometry as monitoring tools in lignocellulosic bioethanol production

    Author : Raquel Perruca Foncillas; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saccharomyces cerevisiae; Biosensors; Flow cytometry; Bioethanol production; Lignocellulosic biomass; Xylose; Strain engineering; Lignocellulosic ethanol; Lignocellulosic inhibitors; Furfural;

    Abstract : The significant environmental impact of the current fossil fuel-based industry is a major concern for society. Consequently, various initiatives are being undertaken to establish a more sustainable industrial model. READ MORE

  4. 2. 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

  5. 3. Short-term adaptation of S. cerevisiae to lignocellulosic inhibitors: Underlying metabolic and physiological changes

    Author : Marlous van Dijk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic inhibitor tolerance; second generation bioethanol; short-term adaptation; differential gene expression; industrial yeast strains;

    Abstract : The limited tolerance of Saccharomyces cerevisiae (budding yeast) to inhibitors present in lignocellulosic hydrolysates is a major challenge in second-generation bioethanol production. Short-term adaptation of the yeast to lignocellulosic hydrolysates during cell propagation has been shown to improve its tolerance, and thus its performance in lignocellulose fermentation. READ MORE

  6. 4. Towards membrane engineering as a tool in cell factory design: A case study on acetic acid tolerance in Saccharomyces cerevisiae

    Abstract : The sustainable production of fuels, chemicals, and materials using renewable resources is a necessity if we are to reduce our ecological footprint and the rate of climate change. Lignocellulosic biomass, the major constituent of plant cell walls, is a renewable raw material with great potential due to its high abundance. READ MORE

  7. 5. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose

    Author : Andreas Rudolf; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Fermentation; Lignocellulose; Hydrolysis; Bioethanol;

    Abstract : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. READ MORE
