A method for removal of free-floating oil from an aqueous environment by bio- dispersion and bio-utilization comprising the steps of: (i) isolating species or strain of bacteria having an ability to utilize hydrocarbons as the only source of carbon; (ii) admixing the bacterium with a fatty substance and hydrocarbon oil to form an oleophilic suspension of the bacterium; (iii) applying the oleophilic suspension of bacteria to a free floating oil in an aqueous environment to disperse and remove free-floating oil therefrom. An oleophilic suspension comprising a fatty substance and a physiologically active bacterial culture of hydrocarbonoclastic bacteria for removing free floating oil from an aqueous environment by bio-dispersion followed by bio-utilization.

La présente invention concerne l'élimination par bio-dispersion et bio-utilisation d'une huile flottant librement dans un environnement aqueux selon un procédé qui consiste à : (i) isoler une espèce ou une souche de bactérie caractérisée par l'aptitude à utiliser les hydrocarbures comme seule et unique source de carbone ; (ii) mélanger la bactérie à une substance grasse en vue de former une suspension bactérienne oléophile ; et (iii) appliquer cette suspension bactérienne oléophile dans un milieu aqueux pour disperser et éliminer l'huile flottante libre. L'invention concerne également une suspension oléophile comprenant une substance grasse et une culture bactérienne physiologiquement active de bactéries capables de provoquer la rupture de la structure hydrocarbonée utilisée pour l'évacuation, par bio-dispersion suivie de bio-utilisation, d'huile flottant librement dans un environnement aqueux.
