  • Patent number: 8551748
    Abstract: Disclosed herein a process for upgrading the liquid hydrocarbon fuels by reducing aromatic content, sulfur content and nitrogen content wherein the process comprising isolating polycyclic aromatic hydrocarbon (PAH) transforming microbes and preparing biocatalyst by mutagenesis, contacting the biocatalyst with the liquid hydrocarbon fuel in an aqueous medium for transforming the aromatic, sulfur, and nitrogen containing compounds to polar substances, subjecting the mixture of biocatalyst and the liquid hydrocarbon fuel to a process of bioconversion, removing the polar substances by liquid-liquid extraction with a polar solvent to obtain dearomatized, desulphurised and denitrogenated liquid hydrocarbon fuel and recovering the upgraded liquid hydrocarbon fuel.

  • Publication number: 20090325271
    Abstract: Disclosed herein is a bio-assisted method for treatment of hydrocarbon contaminated soil employing novel microbes which are capable of decontaminating hydrocarbon contaminated soil having free flowing water or in slurry form or having large amount of gravels. The method comprises adding hydrocarbon releasing microbes followed by adding the microbes capable of degrading the released hydrocarbon to decontaminate the soil, wherein said microbes are grown separately in suitable vessels containing a suitable nutrient medium.

  • Publication number: 20090217571
    Abstract: 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.
