  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. Valorization Of Whole Stillage With Filamentous Fungi Cultivation Using Membrane Bioreactors

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Gülru Bulkan; [2018]
    Nyckelord :whole stillage; membrane bioreactor; filamentous fungi cultivation;

    Sammanfattning : A significant by-product of bioethanol plants is whole stillage, commonly used to produce animal feed due to its nutritious value, has a potential to be used to produce various value-added products while eliminating a costly process step is an alternative approach. In this study, production and separation of additional ethanol, fungal biomass and enzyme were successfully achieved with the cultivation in membrane bioreactors in batch process condition. LÄS MER

  4. 3. Brödrester till bioetanol och djurfoder

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

    Författare :Eh Hser Nay Theimya; [2018]
    Nyckelord :Bioethanol; liquefication; fermentation; animal feed; Bioetanol; förvätskning; fermentering; djurfoder;

    Sammanfattning : Idag produceras bioetanol från grödor som sockerrör, majs, vete osv. Det är ett etiskt dilemma att använda potentiell mat för produktion av bränsle när det samtidigt som det råder matbrist i många länder. En bättre lösning är att använda restprodukter istället. I projektet utnyttjades restprodukter som bröd. LÄS MER

  5. 4. 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

  7. 5. 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
