Mainly based on the use of microorganisms to degrade pollutants, bioremediation appears as a green solution and perfectly adapts to organic pollutants like hydrocarbons. Generally, the aliphatic hydrocarbons have low chemical reactivity and bioavailability. However, they can be degraded by some microorganisms. The biodegradation of a pollutant can be observed by measuring the concentration of consumed oxygen and produced carbon dioxide.
