Title:
BIOLOGICAL METHOD FOR THE DEGRADATION OF COMPLEX MIXTURES OF HYDROCARBONS IN AN AQUEOUS PHASE
Document Type and Number:
WIPO Patent Application WO/2014/135735
Kind Code:
A3
Abstract:
The invention relates to a biological method for reducing the content of hydrocarbons present in an aqueous medium comprising a mixture of hydrocarbons, containing at least one aliphatic alkane; at least one polycyclic aromatic hydrocarbon (PAH); and at least one aromatic hydrocarbon selected from the group formed by benzene, toluene, ethylbenzene, o-xylene, m-xylene, p-xylene and the combinations thereof, comprising placing said aqueous medium contaminated by said mixture of hydrocarbons in contact with a bacterial mixture comprising at least one bacterium that degrades an aliphatic alkane; at least one bacterium that degrades an HAP; and at least one bacterium that degrades said aromatic hydrocarbon. The method can include a chemical or photochemical treatment prior to the biological treatment of the contaminated aqueous medium. The invention also relates to bacteria that can degrade said hydrocarbons.
