1. 6. Teknisk utvärdering av en ny miljövänlig förbehandlingsmetod av biomassaavfall med utspädd salpetersyra

   Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

   Författare :Li Zhi; Oliver Murgårdh; [2012]
   Nyckelord :lignin; cellulosic ethanol; sweet liquor; pre-treatment; dilute nitric acid pulping; SSF; SHF; cellic ctec2; yeast; NABC; bio-refining;

   Sammanfattning : Bio-refining of renewable resources such as waste biomass into value added products has increased rapidly over the last decades. The aim is to find new environmentally friendly yet economically feasible ways of replacing current utilization of non renewable resources. LÄS MER

3. 7. Integrated production of bioethanol and biogas from agricultural residue : comparison of pretreatment methods using mass flow and energy yields analysis

   Master-uppsats, SLU/Dept. of Molecular Biology (until 131231)

   Författare :Debebe Yilma Dererie; [2010]
   Nyckelord :lignocellulose; biofuel; bioenergy; biorefinery; biogas; ethanol; pretreatment; enzymatic saccharification; fermentation;

   Sammanfattning : Lignocellulosic biomasses are believed to reduce the conflict for resource between food and energy production that was criticized in the first generation biofuel production. The aims of this study were two; the first being to compare the effects of three lignocellulose pretreatment methods, lime pretreatment and two steam pretreatment methods, either with or without prior acid impregnation, on the production of bioethanol and biogas from oat straw.

4. 8. Fermentation of lignocellulosic material by the alternative industrial ethanol yeast Dekkera bruxellensis

   Magister-uppsats, SLU/Dept. of Microbiology

   Författare :Emily South; [2010]
   Nyckelord :lignocellulosic mateial; steam explosion; aspen sawdust; enzymatic saccharification; ethanol production; Saccharomyces cerevisiae J672; Dekkera bruxellensis CBS 11269;

   Sammanfattning : Bioethanol is one alternative energy fuel that can be produced from different types of biomass. Second generation bioethanol comes from fermentation of lignocellulosic material and can be seen as a more environmental friendly alternative as e.g. forest residues and agricultural by-products are used.

5. 9. Identification of proteins expressed by the root-rot fungus Heterobasidion annosum when growing on lignocellulose

   Master-uppsats, SLU/Dept. of Molecular Biology (until 131231)

   Författare :Xiaoyu Wang; [2009]
   Nyckelord :Heterobasidion annosum; peptide mapping; lignocellulose; cellulase; cellobiohydrolase; wood degradation; white-rot fungus;

   Sammanfattning : The Root-rot fungus, Heterobasidion annosum, is a major pathogen on spruce and pine trees and is estimated to cause up to 20 % production loss in the forest industry in the temperate region. The genome of H. annosum has recently been sequenced and a total of ~280 carbohydrate-active enzymes have been predicted so far. LÄS MER
