Petroleum-based products are the major source of  energy for industry and

daily life. The technology commonly used for the soil remediation includes

mechanical, burying, evaporation, dispersion,  and washing. However, these

Technologies are expensive and can lead to incomplete decomposition of

contaminants (Zaid A. Pirzada.2015) The Bioremediation technique is a

pollution treatment technology that uses biological systems to catalyse the

destruction or transformation of various chemicals to less harmful forms. The

global market of bioremediation  is becoming increasingly wider and more

successful because it is regarded as a clean technology. (Nalinee

Kumar.et.al,.2013) It is also important because micro-organisms die when

there are no more pollutants to use as substrate. Bioremediation is a versatile process because it can be adapted to suit the specific needs of each site.
