  1. 16. Novel resources enabling comparative regulomics in forest tree species

    Författare :David Sundell; Torgeir Hvidsten; Klaas Vandepoele; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comparative genomics; Web resource; Wood development; RNA-Seq; Forestry; Lignocellulose; Regulomics; High-spatial resolution; Populus tremula; Picea abies; Orthology.; biology; biologi; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ;

    Sammanfattning : Lignocellulosic plants are the most abundant source of terrestrial biomass and are one of the potential sources of renewable energy that can replace the use of fossil fuels. For a country such as Sweden, where the forest industry accounts for 10% of the total export, there would be large economical benefits associated with increased biomass yield. LÄS MER

  2. 17. Perspectives on future bioenergy use and trade in a European policy context

    Författare :Julia Hansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sweden; bioenergy trade; EU; policy; bioenergy; co-generation; renewable electricity; biomass; co-firing; district heating; biofuels for transportation; gasification;

    Sammanfattning : This thesis, which consists of five separate papers, analyses the possibilities for increasing the use and trade of bioenergy, in a European policy context. In Paper I we investigate whether different policy objectives underlying the promotion of bioenergy (cost-effective climate change mitigation, reduced dependency on imported fuels, and job creation) agree on which bioenergy options should be used.

  3. 18. Metabolic Control Points in Ethanolic Fermentation of Xylose by Saccharomyces cerevisiae

    Författare :David Runquist; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transcriptomics; Xylose reductase; Saccharomyces cerevisiae; Xylose; Ethanol; Transport; Lignocellulose;

    Sammanfattning : Baker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. LÄS MER

  4. 19. Biogas Production from Lignocelluloses : Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

    Författare :Anna Teghammar; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology;

    Sammanfattning : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. LÄS MER

  5. 20. Understanding and improving microbial cell factories through Large Scale Data-approaches

    Författare :Daniel Brink; Teknisk mikrobiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microbiology; lignocellulose; lignin; D-xylose; Saccharomyces cerevisiae; Pseudomonas putida; bioinformatics; genome assembly; flow cytometry; metabolic engineering; sugar sensing signalling;

    Sammanfattning : Since the advent of high-throughput genome sequencing methods in the mid-2000s, molecular biology has rapidly transitioned towards data-intensive science. Recent technological developments have increased the accessibility of omics experiments by decreasing the cost, while the concurrent design of new algorithms have improved the computational work-flow needed to analyse the large datasets generated.
