5. 4. Towards renewable chemicals production in cyanobacteria

   Författare :Kateryna Kukil; Pia Lindberg; Yu Jianping; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Synechocystis PCC 6803; metabolic engineering; succinate; phenylpropanoids; laboratory evolution; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Sammanfattning : The intensive fossil fuel combustion by humanity resulted in the increase of atmospheric CO2 concentration creating the greenhouse effect, which in turn causes severe environmental problems. Thus, humanity should find solutions to decrease dependency on fossil hydrocarbons in order to lower CO2 emission into the atmosphere. LÄS MER

7. 5. New Roads for an Ancient Enzyme : Whole-Cell Studies and New Cofactors for [FeFe] Hydrogenases

   Författare :Marco Lorenzi; Gustav Berggren; Hannah Shafaat; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; [FeFe] hydrogenases; hydrogen; catalysis; photocatalysis; spectroscopy; whole-cell; semi-artificial enzymes; Chemistry with specialization in Molecular Biomimetics; Kemi med inriktning mot molekylär biomimetik;

   Sammanfattning : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. LÄS MER
