In addition to degrading benzene, ethylbenzene, toluene, and xylene (major components of gasoline), Pseudomonas putida also breaks down styrene, which means it may someday be used for biodegradation of polystyrene (more commonly known by its trademark, Styrofoam). Besides being useful for bioremediation, Pseudomonas putida is symbiotic with some plants, encouraging their growth and protecting them from pathogenic bacteria. It is also a major food source for springtails. Pseudomonas putida is generally nonpathogenic, but is closely related to the important human pathogen, Pseudomonas aeruginosa, making it a useful model for studying that bacterium.
