  1. 1. Analysis and Valorization of Bark from Silver Birch, Scots Pine, and Norway Spruce : Compositional analysis of bark from common Swedish trees in forestry, to optimize sustainability procedures and monetary value of bark residue

    Kandidat-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Isak Lindbäck; [2022]
    Nyckelord :;

    Sammanfattning : Silver birch, Scots pine, and Norway spruce are the three most common types of trees in Sweden and make up to 90% of standing volume in Swedish forests (Skogsstyrelsen 2015, 3). With millions of cubic meters of wood being cut down annually, bark and other residues that cannot be used for sawn timber is left over and burnt for energy. LÄS MER

  3. 2. Signal peptide exchange for higher expression of Bjerkandera adusta Loosenin 1 in P. pastoris

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Linus Brinkenstråhle; [2018]
    Nyckelord :Loosenin; cellulose; signal peptide; expansin; Pichia pastoris; recombinant expression;

    Sammanfattning : The protein Loosenin 1 from the wood degrading fungus Bjerkandera adu-sta (BaLOOS1) has been shown to loosen up recalcitrant biomass and en-hance enzymatic saccharification. BaLOOS1 is the only loosenin protein that has been biochemically characterised so far. LÄS MER

  4. 3. Potential of Steam Pretreated Jerusalem Artichok Stem for Ethanol Production

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Adam Eliasson; [2017]
    Nyckelord :SSF; Simultaneous Saccharification and Fermentation; Lignocellulose; Bioethanol; Second generation Bioethanol; Steam Explotion; Jerusalem Artichoke; Enzymatic Hydrolysis; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : To reach the goals set for the reduction of green house gas by the European Union the use of fossil fuels has to be reduced. To do this alternative fuels such as bioethanol have to substitute fossil fuels. LÄS MER

  5. 4. Combined production of bioethanol and biogas from wheat straw

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Victor Gustafson; [2015]
    Nyckelord :lactic acid; chemical engineering; biogas; enzymes; enzymatic hydrolysis; energy recovery; ethanol red; bioethanol; wheat straw; steam pretreatment; inhibitors; kemiteknik; Technology and Engineering;

    Sammanfattning : Currently the production cost of lignocellulosic ethanol is considered to be relatively high. Large fractions of the production cost come from the raw material and the energy consumed in the distillation. Therefore it is desirable to have a process that yields high concentration of ethanol and maximizes the utilization of the biomass. LÄS MER

  7. 5. Saccharification of lignocellulose

    Kandidat-uppsats, Malmö högskola/Fakulteten för hälsa och samhälle (HS)

    Författare :Mohamed Warsame; [2012]
    Nyckelord :Wheat straw; Saccharification; Cellulose; Hemicellulose; Pretreatment; Lignocellulose;

    Sammanfattning : Den ökande efterfrågan på energi och den förväntade nedgången i råoljeproduktion har lett till ett enormt sökande efter nya energikällor.Cellväggen i växter består till stor del av lignocellulosa som i sin tur innehåller cellulosa och hemicellulosa. Dessa polysackarider är av stor betydelse för sökandet efter förnyelsebar energi. LÄS MER
