Abstract
The accumulation of all kinds of releases into the environment has become a major concern for several decades. It resulted in a strong awareness in the world. The race might seem unwinnable given the tremendous increase in industrial activity, consumption and development of intensive agriculture. One of the most formidable of global pollution by synthetic chemicals is in the growth of emissions of hydrocarbons in the environment. The impact of this pollution on the environment and health is particularly linked to the spread of dangerous molecules in the environment and their transfer into the groundwater and the food chain. The treatments used for soil remediation are numerous, and for years now, new technologies are developing. In the field, the techniques of heat treatment and physical-chemical are most common. And biological techniques that use the power of decontaminating microorganisms are often considered as reserved for a narrow class of compounds such as petroleum hydrocarbons . The removal of oil from the terrestrial environment requires the involvement of various biotic and biotic factors. Among these factors, biodegradation by microorganisms, particularly bacteria is the most important natural process in cleaning. The phenomenon of biodegradation represents all the mechanisms of transformation of a contaminant in various by-products by the action of microorganisms.
