  2. 1. Trametes versicolor as biodegrader and biocatalyst when using lignocellulose for ethanol production

    Author : Marie Holmgren; Anita Sellstedt; Mohammad Taherzadeh; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; 5-carbon; 6-carbon; Trametes versicolor; xylose reductase; xylitol dehydrogenase; xylulokinase; phenolics; levulinic acid; HMF; furfural; biodegrader; biocatalyst; pretreatment; xylanase; beta-glucosidase;

    Abstract : Energy consumption has increased rapidly during the last century due to population growth and greater industrialization. Lignocellulosic-based biofuels are being developed as alternatives to fossil fuels. For many years the question of how 5-carbon sugars in biomass are utilized in nature has been a vexed one.

  4. 2. The Biodiversity of Hydrogenases in Frankia : Characterization, regulation and phylogeny

    Author : Melakeselam Leul Zerihun; Anita Sellstedt; Kornel Kovács; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Frankia; immunoblotting; gene expression; uptake hydrogenase; hydrogen-evolving hydrogenase; nickel; phylogeny; Molecular biology; Molekylärbiologi;

    Abstract : All the eighteen Frankia strains isolated from ten different actinorhizal host plants showed uptake hydrogenase activity. The activity of this enzyme is further increased by addition of nickel. Nickel also enhanced the degree of hydrogenase transfer into the membranes of Frankia, indicating the role of this metal in the processing of this enzyme. READ MORE

  5. 3. Autotrophic and heterotrophic culture of Nordic microalgae in wastewater for lipid production

    Author : Jean Claude Nzayisenga; Anita Sellstedt; Francesco G. Gentili; Christiane Funk; Ashton Keith Cowan; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is well established that society’s main means for producing energy, the combustion of fossil fuels, is unsustainable and contributes to global warming. Microalgae have high potential for the production of biodiesel and energy source that can at least partially replace fossil fuels. READ MORE
