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

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Pálína Haraldsdóttir; [2018]
    Keywords : Applied microbiology; Teknisk mikrobiologi; Technology and Engineering;

    Abstract : 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. READ MORE
