  1. 1. Metabolic engineering strategies to increase n-butanol production from cyanobacteria

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Josefine Anfelt; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; biofuels; butanol; synthetic scaffold; CRISPRi; solvent tolerance; Biotechnology; Bioteknologi;

    Abstract : The development of sustainable replacements for fossil fuels has been spurred by concerns over global warming effects. Biofuels are typically produced through fermentation of edible crops, or forest or agricultural residues requiring cost-intensive pretreatment. READ MORE

  2. 2. Metabolic Engineering of Synechocystis PCC 6803 for Butanol Production

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rui Miao; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; biofuel; isobutanol; 1-butanol; metabolic engineering; protein engineering; Biokemi; Biochemistry;

    Abstract : There is an urgent demand for renewable alternatives to fossil fuels since the extraction and utilization cause a series of environmental problems in the world. Thus, the utilization of solar energy has attracted much attention in the last decades since there is excess amount of light on Earth. READ MORE

  3. 3. Zeolite adsorbents and catalysts for the recovery and production of biochemicals

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Abrar Faisal; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Adsorbents; Catalyst; Butanol; Arginine; ZSM-5; Chemical Technology; Kemisk teknologi;

    Abstract : Fossil based energy resources are dominating the world’s primary energy consumption for the last century. However, with decreasing crude oil reservoirs and the role they play in global warming by emitting greenhouse gases, the focus has been turned towards improved utilization of renewable resources and the need for new, sustainable fuels and chemicals is more urgent than ever.

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

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Lina Lindahl; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; butanol; inhibitors; lipidomics; Key words: Lignocellulose; Zygosaccharomyces bailii; molecular dynamics simulations; membrane permeability; carbon-14 uptake; ethanol; robustness;

    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

  5. 5. Experimental Study of Using Butanol or Octanol Blends as Alternative Fuels in Diesel Engines

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Tankai Zhang; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : With the increased travel demand, the consumption of fossil fuels, as the main energy source for transportation, has risen sharply over the last few decades. Fossil fuels are considered a non-renewable resource. In addition, burning them in internal combustion engines can generate a large amount of greenhouse gas (GHG) emissions. READ MORE
