  1. 1. Ethanol from woodCellulase enzyme production

    Author : Zsolt Szengyel; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; FPA measurement; acetic acid; furfural; non-volatile; volatile; inhibition; pH; carbon source; liquid; solid; softwood; hardwood; cellulases; production; Kemiteknik och kemisk teknologi; Biotechnology; Bioteknik;

    Abstract : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. READ MORE

  2. 2. Enzyme catalysis towards bio-based UV-curable buildingblocks

    Author : Maja Finnveden; Mats Martinelle; Katja Loos; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Enzyme; Enzymatic Polymerizations; Biocatalysis; Lipase; CalB; MsAcT; Substrate specificity; Selectivity; Polymer Chemistry; UV-curring; Biotechnology; Bioteknologi;

    Abstract : Polymeric materials are found in virtually all areas of daily life; they are found in everything from packages keeping our food safe to the buildings where we spend our days, and the production is a worldwide industry. Although polymeric materials play a big part in sustainable solution’s, a lot can be done to develop more environmental methods for producing them. READ MORE

  3. 3. Building blocks for polymer synthesis by enzymatic catalysis

    Abstract : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. READ MORE

  4. 4. Dietary fibre production from oat hulls

    Author : Eva Schmitz; Bioteknik; []

    Abstract : The current threats of climate change connected to the unsustainable consumption of fossil resources paired with an increasing world population demands the exploration of alternative raw materials for the production of food, fuel and specialty chemicals. Agricultural waste streams present suitable sources due to their availability in large quantities at low costs without competing with current food production. READ MORE

  5. 5. Feruloyl esterases - Evaluation of their potential for biotechnological applications

    Author : Cyrielle Bonzom; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-domain enzyme; acetyl esterase; enzyme immobilization; N-glycosylation; carbohydrate active enzyme family 1; acetyl xylan esterase; heterologous production; polysaccharide utilization loci; enzyme stability; feruloyl esterase;

    Abstract : Owing to the current efforts to find sustainable alternatives to petrochemical based industries and technologies, enzymatic degradation and valorization of plant biomass has been attracting interest. Due to the complexity of plant biomass, an array of enzymes is required to hydrolyze it, including esterases. READ MORE
