  4. 7. 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

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

    Author : Tobias Modig; Avdelningen 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

  6. 9. Ethanol from Lignocellulose: Physiological Effects of Inhibitors and Fermentation Strategies

    Author : Mohammad Taherzadeh Esfahani; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fermentation; dilute-acid hydrolyzate; ethanol; hydroxymethyl furfural; furfural; acetic acid; lignocellulose; fed-batch; yeast; pantothenate; control; inhibition; HMF;

    Abstract : Fermentative ethanol production from dilute-acid hydrolyzates of wood using the yeast Saccharomyces cerevisiae was investigated. Of known inhibitors in hydrolyzates, acetic acid, furfural and hydroxymethyl furfural (HMF) were found in the highest concentrations (up to about 10 g/l). READ MORE

  7. 10. Fermentation of undetoxified dilute acid lignocellulose hydrolysate for fuel ethanol production

    Author : Tomas Brandberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrolysate; lignocellulose; Saccharomyces cerevisiae; nitrogen limitation; microaerobic conditions; cell recirculation; continuous fermentation; Mucor indicus; ethanol; cell retention;

    Abstract : Important aspects of ethanol production from undetoxified dilute acid lignocellulose hydrolysate are covered in this thesis, which primarily focuses on the use of Saccharomyces cerevisiae (Baker's yeast) as the biocatalyst. Nine different strains of S. READ MORE
