Summary:Disclosed herein is a method for producing ultra-low-sulfur content hydrocarbon fuel and product thereof. The method comprises selective biocatalytic oxidation of sulfur containing compounds present in the fuels employing enzyme lipase as biocatalyst in presence of controlled and incremental amount of hydrogen peroxide and carboxylic acid without using water or any co-factor for the reactivity of said enzymes. L'invention concerne un procédé de production de combustibles à hydrocarbures à très faible teneur en soufre et les combustibles ainsi obtenus. Le procédé selon l'invention comporte l'oxydation biocatalytique sélective de composés contenant du soufre présents dans des combustibles, au moyen de lipases enzymatiques en tant que biocatalyseurs, en présence d'une quantité commandée et incrémentielle de peroxyde d'hydrogène et d'acide carboxylique, sans utiliser d'eau ou tout autre cofacteur pour la réactivité desdites enzymes.
