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. EVALUATION OF BIOLOGICAL STRATEGIES TO ENHANCE HYDROLYSIS DURING ANAEROBIC DIGESTION OF COMPLEX WASTE

   Author : Dores Cirne; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; kontroll av utsläpp; Biotechnology; bioaugmentation; enzyme addition; Environmental technology; pollution control; FISH; cellulose; inhibition; lipids; Clostridium lundense; hydrolysis; complex substrate; Anaerobic digestion; renewable energy; Bioteknik; LCFA;

   Abstract : Anaerobic digestion (AD) offers considerable potential in the production of energy from renewable sources, and is being increasingly recognised as a sustainable technology for the treatment of waste. The production of energy from waste such as municipal solid waste (MSW), lipid-rich waste, and agricultural biomass and waste may play an important role in the production of renewable energy given the huge amounts of these types of waste generated annually.

5. 3. Molecular Simulation of Enzyme Catalysis and Inhibition

   Author : Sinisa Bjelic; Johan Åqvist; Adrian J. Mulholland; Uppsala universitet; []
   Keywords : Theoretical chemistry; enzyme catalysis; enzyme inhibition; computer simulations; molecular dynamics; empirical valence bond method; structure-based inhibitor design; Teoretisk kemi;

   Abstract : The reaction mechanisms for the hemoglobin degrading enzymes in the Plasmodium falciparum malaria parasite, plasmepsin II (Plm II) and histo-aspartic protease (HAP), have been analyzed by molecular simulations. The reaction free energy profiles, calculated by the empirical valence bond (EVB) method in combination with molecular dynamics (MD) and free energy perturbation (FEP) simulations are in good agreement with experimental data.

6. 4. Methane and Volatile Fatty Acids Production from Toxic Substrate

   Author : - Lukitawesa; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

   Abstract : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. READ MORE

7. 5. Cognitive function studied in animal models of schizophrenia

   Author : Erik Pålsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phencyclidine; nitric oxide; prepulse inhibition; latent; nitric oxide; prepulse inhibition; latent inhibition; habituation; NMDA receptor; rat; mouse; cognition; schizophrenia;

   Abstract : Cognitive dysfunction is considered a core deficit of schizophrenia, which currently lacks effective pharmacological treatment. In order to identify novel and more effective drug treatments, translational experimental animal models of cognitive dysfunction are required. Schizophrenia-like symptoms can be induced in humans by phencyclidine (PCP). READ MORE
