摘要： The present invention relates to a method for the production of an olefin from at least one renewable natural raw material. More specifically, the present invention refers to a method whereby is obtained ethylene or propylene at high yield and high productivity by means of the anodic electrodecarboxylation reaction of carboxylic acids, respectively propionic acid and butyric acid, produced from fermentation, preferably of sugars. The method for generating the olefin is simple, has a low cost, and provides low emissions of greenhouse gasses of fossil origin.

摘要： The invention provides fermentative methods for producing n-propanol. The methods of the invention involve providing a suitable carbon source, a microorganism expressing the dicarboxylic acid pathway, reducing equivalents, and at least one gene coding for an enzyme that catalyzes the conversion of propionate/propionyl-CoA into n-propanol. The methods further involve contacting the carbon source and reducing equivalents with the microorganism under conditions favorable for the production of n-propanol. Also provided are methods for producing propylene and polypropylene from the n-propanol and microorganisms suitable for use in the methods of the invention
