  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

  3. 2. Production of bioethanol from wheat straw hydrolysate using reverse membrane bioreactor (rMBR)

    Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Jessica Khin San; [2018]
    Nyckelord :Reverse membrane bioreactor; wheat straw; fermentation; ethanol; furfural; diffusion rate;

    Sammanfattning : The second-generation bioethanol production in which lignocellulosic material is used as feedstock faces some difficulties. Lignocellulosic materials have to be pretreated prior to fermentation. LÄS MER
