  1. 1. 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

  2. 2. Modelling and Optimisation of Integrated Biotechnical Processes -Application to the Fermentative Production of Lactic Acid from Wheat Flour

    Author : Christina Åkerberg; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; economy; wheat flour; starch; lactic acid; kinetics; simulation; modelling; optimisation; Kemiteknik och kemisk teknologi;

    Abstract : Biotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. READ MORE

  3. 3. Continuous ethanol production from dilute-acid hydrolyzates : detoxification and fermentation strategy

    Author : Ronny Purwadi; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The production of fuel ethanol from cellulosic biomass is of growing interest around the world. Lignocellulosic residuals can be used to produce transportation fuel, with the overall process having little net production of greenhouse gases. READ MORE

  4. 4. Biobased production of succinic acid by Escherichia coli fermentation

    Author : Christian Andersson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Abstract : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). The present thesis illustrates different aspects of biobased succinic acid production by a metabolically engineered E. coli strain. READ MORE

  5. 5. Metabolic Control Points in Ethanolic Fermentation of Xylose by Saccharomyces cerevisiae

    Author : David Runquist; Teknisk mikrobiologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transcriptomics; Xylose reductase; Saccharomyces cerevisiae; Xylose; Ethanol; Transport; Lignocellulose;

    Abstract : Baker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. READ MORE
