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

    Författare :Josefine Anfelt; Elton P. Hudson; Mathias Uhlén; Patrik R. Jones; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cyanobacteria; metabolic engineering; biofuels; butanol; synthetic scaffold; CRISPRi; solvent tolerance; Bioteknologi; Biotechnology;

    Sammanfattning : 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. LÄS MER

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

    Författare :Rui Miao; Peter Lindblad; Pia Lindberg; Felix Ho; Shota Atsumi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; biofuel; isobutanol; 1-butanol; metabolic engineering; protein engineering; Biokemi; Biochemistry;

    Sammanfattning : 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. LÄS MER

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

    Författare :Abrar Faisal; Mattias Grahn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Adsorbents; Catalyst; Butanol; Arginine; ZSM-5; Chemical Technology; Kemisk teknologi;

    Sammanfattning : 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.

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

    Författare :Lina Lindahl; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. Improving cyanobacteria productivity: From theory to assay

    Författare :Kiyan Shabestary; Elton P. Hudson; Daniel Ducat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metabolic engineering; growth-coupling; growth-arrest; cyanobacteria; CRISPRi; CRISPRi library; flux balance analysis; genome-scale model; butanol; lactate; isoprene; Bioteknologi; Biotechnology;

    Sammanfattning : Bio-based production of biochemicals and biofuels holds great promises for the transition towards a more sustainable society. With increasing levels of carbon dioxide (CO2) in the atmosphere, cyanobacteria stand apart as natural catalysts directly converting CO2 and light to product. LÄS MER
