Title
(EN) BIOCONVERSION OF SHORT-CHAIN HYDROCARBONS TO FUELS AND CHEMICALS
(FR) BIOCONVERSION D'HYDROCARBURES À CHAÎNE COURTE EN CARBURANTS ET PRODUITS CHIMIQUES
Abstract
(EN)
An engineered microorganism(s) with novel pathways for the conversion of short- chain hydrocarbons to fuels and chemicals (e.g. carboxylic acids, alcohols, hydrocarbons, and their alpha-, beta-, and omega-functionalized derivatives) is described. Key to this approach is the use of hydrocarbon activation enzymes able to overcome the high stability and low reactivity of hydrocarbon compounds through the cleavage of an inert C-H bond. Oxygen-dependent or oxygen-independent activation enzymes can be exploited for this purpose, which when combined with appropriate pathways for the conversion of activated hydrocarbons to key metabolic intermediates, enables the generation of product precursors that can subsequently be converted to desired compounds through established pathways. These novel engineered microorganism(s) provide a route for the production of fuels and chemicals from short chain hydrocarbons such as methane, ethane, propane, butane, and pentane.

L'invention concerne un ou des microorganismes obtenus par génie génétique comportant de nouvelles voies pour la conversion d'hydrocarbures à chaîne courte en carburants et en produits chimiques (par exemple des acides carboxyliques, des alcools, des hydrocarbures, et leurs dérivés fonctionnalisés en alpha, bêta et oméga). L'élément clé dans cette démarche est l'utilisation d'enzymes d'activation des hydrocarbures capables de venir à bout de la stabilité élevée et de la faible réactivité des composés d'hydrocarbures par clivage d'une liaison C-H inerte. Des enzymes d'activation dépendantes ou pas de l'oxygène peuvent être exploitées à cet effet : lorsqu'elles sont combinées à des voies appropriées pour la conversion d'hydrocarbures activés en intermédiaires métaboliques clés, celles-ci permettent la génération de précurseurs de produit qui peuvent ensuite être convertis en composés désirés par des voies déjà connues. Ce ou ces nouveaux microorganismes obtenus par génie génétique permettent la production de carburants et de produits chimiques à partir d'hydrocarbures à chaîne courte tels que le méthane, l'éthane, le propane, le butane et le pentane.
