  2. 1. Fuel Ethanol Production from Corn Stover: Optimization of Steam Pretreatment and Improvement of Simultaneous Saccharification and Fermentation

    Author : Karin Öhgren; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuels and explosives technology; petrochemistry; Carbochemistry; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Energiforskning; corn stover; Energy research; prehydrolysis; enzymatic hydrolysis; SSF; SO2; steam pretreatment; Ethanol production; Petrokemi; bränslen; sprängämnen; pentose fermentation;

    Abstract : Fuel ethanol, produced from biomass, could well be tomorrow's replacement for gasoline. This thesis deals with the production of fuel ethanol from corn stover using an enzymatic process consisting of the following main steps: steam pretreatment of the raw material, enzymatic hydrolysis, fermentation of the sugars and ethanol refining.

    Abstract : In view of global climate change and the increasing energy demand there is a need for renewable energy resources. This thesis discusses an energy-driven biorefinery concept based on the agricultural residues corn stover and wheat straw. The work is divided into two main parts. READ MORE

  5. 3. Succinic acid production using metabolically engineered Escherichia coli

    Author : Christian Andersson; []
    Keywords : 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). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. READ MORE

  6. 4. Mutagenesis in wheat: An approach to make saline green!

    Author : Johanna Lethin; Göteborgs universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wheat; Mutagenesis; Salinity;

    Abstract : The raising salinity in the soils around the world have been widely studied during the last decades due to the massive loss in agricultural land. Today, nearly 8% of the world’s arable land can no longer be used for crop cultivation due to salt contaminations, and more than half of the countries in the world are affected. READ MORE

  7. 5. Biobased production of succinic acid by Escherichia coli fermentation

    Author : Christian Andersson; Gen Larsson; Luleå tekniska universitet; []
    Keywords : 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
