to crude oil are extreme environments for living organisms. Although being a
rich hydrocarbon source, crude oil is highly hydrophobic being inaccessible for
microorganisms and several byproducts of its degradation are highly toxic for
most living forms. Different prokaryote species have been found specifically
associated with diverse crude oil environments. The metabolic interactions
among these co-occurring species have not been fully deciphered yet.
Understanding how microbial consortia metabolize crude oil will constitute the
basis for designing biotechnological solutions for environmental applications
such as microbial enhanced oil recovery.
