  1. 1. Efficient Conversion of Lignocellulose Hydrolysates- Yeast Tolerance and Redox Metabolism

    Author : Tobias Modig; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metabolism; Biokemi; metabolism; hyperosmotic stress; Biochemistry; S. cerevisiae; anaerobic growth; inhibitor tolerance; furfural; lignocellulose; HMF; Biotechnology; Bioteknik;

    Abstract : The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. READ MORE

  3. 3. Fermentation Inhibitors in the Production of Bio-ethanol: Detoxification of Lignocellulose Hydrolyzates and Physiological Effects of Furfural on Yeast

    Author : Ilona Sárvári Horváth; Chalmers University of Technology; []
    Keywords : detoxification; fermentation inhibitors; metabolic flux analysis; Saccharomyces cerevisiae; lignocellulose; ethanol; chemostat; furfural conversion;

    Abstract : Different strategies to overcome inhibitor problems in the production of bio-ethanol from lignocellulose hydrolyzates with the yeast Saccharomyces cerevisiae were examined. The strategies included detoxification prior to fermentation and in situ detoxification of furfural. A strain development for improved inhibitor tolerance was also initiated. READ MORE

  4. 4. Improving the Response of Saccharomyces cerevisiae to Lignocellulosic Hydrolysate Inhibitors in Ethanolic Fermentation

    Author : Joao Almeida; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; furfural; ethanol; fermentation; phenolics; furaldehyde; HMF; ADH1; xylose reductase; tolerance; Saccharomyces cerevisiae; Lignocellulosic hydrolysate inhibitors; ADH6;

    Abstract : The production of ethanol based on lignocellulosic biomass requires the fermentation of a hydrolysate containing hexose and pentose sugars in an inhibitory environment. In fact, the lignocellulosic hydrolysate obtained from pretreatment and hydrolysis of the raw material contains a variety of inhibitory compounds, including (i) the furaldehydes 5-hydroxymethyl-2-furaldehyde (HMF) and 2-furaldehyde (furfural), (ii) weak acids (e.

  5. 5. Ethanol from woodCellulase enzyme production

    Author : Zsolt Szengyel; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; FPA measurement; acetic acid; furfural; non-volatile; volatile; inhibition; pH; carbon source; liquid; solid; softwood; hardwood; cellulases; production; Kemiteknik och kemisk teknologi; Biotechnology; Bioteknik;

    Abstract : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. READ MORE
