Biodegradation of Petroleum Hydrocarbons and The Factors Effecting Rate of Biodegradation |Biomedgrid

In the recent decade, environmental pollution of petroleum and petrochemical products has attracted much attention. In the modern world, contamination of natural environment with oil products causes soil pollution. Therefore, petroleum hydrocarbons have been shown harmful effects on the environment and particularly to human beings. Earlier, many traditional techniques were used to treat such hydrocarbons on large scale. However, bioremediation technique is considered environment friendly due to relatively low cost and utilizing a natural microbial to reduce the concentrations and toxicity of various chemicals, aromatic, and aliphatic hydrocarbons. In this context, certain bacterial strains have been demonstrated to be able to breakdown chemical compounds present in petroleum products. The goal of this review paper is to discuss the most possible ways for biodegradation of petroleum hydrocarbons and highlight the environmental conditions which affecting the rate of biodegradation. In conclusion, by optimizing the environmental conditions such as oxygen, temperature, pH, moisture etc and other nutrients will maximize the hydrocarbon quickly in the natural environment.
