  1. 1. Construction and Characterization of 3rd Generation Saccharomyces cerevisiae Strains for PHB production form Xylose

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Pálína Haraldsdóttir; [2018]
    Nyckelord :Applied microbiology; Teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. LÄS MER

    Sammanfattning : This paper discusses the potential of gasoline, ethanol and methanol ternary blend as an alternative passenger car fuel in Sweden. Sweden has set various targets aimed to reduce its GHG emissions and to increase the share of renewables in the transportation sector. LÄS MER

  4. 3. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emelie Graham; [2015]
    Nyckelord :Ecosystem Science; Physical Geography; 2nd generation biofuels; furans; tropospheric chemistry; ozonolysis; atmospheric kinetics; computational chemistry; IR Spectroscopy; Atmospheric Science Biochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. LÄS MER

  5. 4. Cost benefit and risk analysis of biofuel production in Pakistan

    Master-uppsats, SLU/Dept. of Economics

    Författare :Asma Naureen; [2013]
    Nyckelord :biofuel; cost benefit analysis; Pakistan; feedstock; Jatropha; Corn; Switchgrass; Sugarcane;

    Sammanfattning : To meet rising demand of energy, bioenergy is getting great attention in an energy-deficient country; Pakistan. In this respect, food and non-food feedstocks are being examined economically, environmentally and in terms of energy balance. Work in this thesis deals with supply side analysis of liquid bioenergy options in Pakistan. LÄS MER

  7. 5. Sustainable Production of Fuel : A Study for Customer Adoption of 2nd Generation of Biofuel

    Master-uppsats, Företagsekonomiska institutionen

    Författare :Ying Jin; [2010]
    Nyckelord :customer adoption; biofuel;

    Sammanfattning : Abstract Finding a new fuel to substitute gasoline which reducing rapidly every year, is an urgent problem in the world. In this situation, biofuel is considered to be one kind of new fuel which make no pollution. Nowadays, 1st generation biofuel is familiar with people and adopted by customers, which make it have a stable market share. LÄS MER
