Abstract
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/strains of bacteria having an ability to utilize hydrocarbons as the only source of carbon; (ii) admixing the bacteria with a fatty substance and hydrocarbon oil to form an oleophilic suspension comprising a physiologically active bacterial culture of hydrocarbonoclastic bacteria, the fatty substance comprising an oleophilic nutrient as a source of nitrogen and phosphorus for the bacteria, and (iii) applying the oleophilic suspension of the bacteria to a free floating oil in an aqueous environment to disperse and remove free-floating oil therefrom.
