Hydrocarbon-degrading bacteria are phylogenetically and physiologically diverse and employ layered strategies to sense hydrocarbons, respond transcriptionally, and then move toward an oil source. They then produce biopolymers that increase hydrocarbon bioavailability. This SnapShot highlights how these bacteria respond to and then remove hydrocarbon contaminants from the environment.
