2. 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

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

   Author : Maja Finnveden; Mats Martinelle; Katja Loos; KTH; []

   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

6. 4. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

   Author : Nina Johansson; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

   Abstract : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. READ MORE

7. 5. Dietary fibre production from oat hulls

   Author : Eva Schmitz; Bioteknik; []
