2. 1. The kinetics of cellulose enzymatic hydrolysis : Implications of the synergism between enzymes

   Author : Priit Väljamäe; Jan-Christer Janson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Acetobacter; Cellobiohydrolase; Cellobiose; Cellulase; Cellulose; Diffusion; Endoglucanase; Hydrolysis; Inhibition; Kinetics; Model; Product; Substrate; Surface; Synergism; Trichoderma reesei; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

   Abstract : The hydrolysis kinetics of bacterial cellulose and its derivatives by Trichoderma reesei cellulases was studied. The cellulose surface erosion model was introduced to explain the gradual and strong retardation of the rate of enzymatic hydrolysis of cellulose. READ MORE

4. 2. The role of the thromboinflammatory response under hemolytic conditions : pathophysiological mechanisms and therapeutic inhibition

   Author : Alexandra Gerogianni; Per H. Nilsson; Camilla Mohlin; Tom Eirik Mollnes; Kristina Nilsson Ekdahl; Mihály Józsi; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hemolysis; heme; thromboinflammation; biomaterials; complement inhibition; LVAD; IONPs; Biomedical Sciences; Biomedicinsk vetenskap; Immunologi; Immunology;

   Abstract : In blood circulation, the complement and the coagulation cascades, together with platelets and endothelial cells form a complex network of crosstalk. When dysregulated, these interactions can lead to inflammation in combination with thrombosis (thromboinflammation) and the manifestation of pathophysiological complications. READ MORE

5. 3. Do you dare to think outside the box? : Impacts of alcohol, negative affect and evaluation apprehension on inhibition of creative performance

   Author : Nina Svensson; Per Kristensson; Renée Perrin-Wallqvist; Ingegerd Carlsson; Karlstads universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Creativity; inhibition; group work; alcohol; emotion; creative self-efficacy; evaluation apprehension; Psykologi; Psychology;

   Abstract : Conditions relating to evaluation apprehension, alcohol and affect were investigated in relation to creative performance. Study I compared group work with individual work, and control conditions were compared with de Bono creativity-enhancing techniques. READ MORE

6. 4. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

   Author : Tarek Dishisha; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

7. 5. Fermentative hydrogen and methane productions using membrane bioreactors

   Author : Julius Akinbomi; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

   Abstract : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.
