Abstract

Provided is a composition that may include an aqueous phase, and extremophilic bacteria having signal transduction chemotaxis machinery and nanoemulsion oil droplets including metal-silica nanoparticles attached to a surface thereof. Further provided is a method for treating an oil reservoir, that may include introducing into the oil reservoir an extremophilic bacteria having signal transduction chemotaxis machinery and nanoemulsion oil droplets including metal-silica nanoparticles attached to a surface thereof. Further provided is method for bacteria mediated enhanced oil recovery that may include introducing extremophilic bacteria downhole to an oil reservoir. The method may further include triggering cell lysis of the extremophilic bacteria, mobilizing the oil trapped by the biosurfactants released from lysed extremophilic bacteria, and producing the oil trapped by the biosurfactants from the oil reservoir.
