Gasoline Contamination: Solutions Through Bioremediation

Gasoline, in particular, has been the focus of substantial biodegradation and bioremediation research. The gasoline components benzene, tolune, ethylbenzene, and xylene (together known as BTEX) are relatively easy to bioremediate for several reasons:
 * They are relatively soluble compared to other common contaminants and other gasoline components. They can serve as the primary electron donor for many bacteria widely distributed in nature.

They are rapidly degraded relative to other contaminants.

The bacteria that degrade BTEX grow readily if oxygen is available.
