Much of the early work on the microbial utilization of petroleum hydrocarbons, conducted in the s and s, was done with the goal of using hydrocarbons as substrates for producing microbial biomass (Shennan, ; Champagnat, ; Champagnat and Llewelyn, ; Cooney et al., ; Ballerini, ).Petroleum was viewed as an inexpensive carbon source and single cell protein   Specific challenges of in situ bioremediation: Bioremediation techniques have been tested in laboratories with good results but the transfer to the field has been often quite difficult (Sturman et al., ; Allard and Neilson, ).?doi=rjet   For the preparation of soil extract and the enrichment of naphthalene- BTEX (benzene, toluene, ethyl benzene, and o- m- p-xylene)- and aliphatic hydrocarbon-degrading bacteria, soil Abstract.

This dependency on fossil fuels has resulted in serious environmental issues in recent times. Petroleum contaminated soils must be treated to ensure that human health and the environment remain :// Bioremediation is a viable mechanism for treating soils contaminated with petroleum hydrocarbons.

Bioremediation strategies range from encouraging natural biodegradation processes (biostimulation) to supplementing the existing system with microorganisms able to degrade the contamination (bioaugmentation) and to monitoring and verifying natural processes (natural attenuation).

Permeable reactive barriers (PRBs) technology has received a great deal of attention for in-situ groundwater bioremediation in past decades. In this regard, calcium peroxide (CaO 2) as an oxygen releasing compound (ORC) can slowly release oxygen and remediate hydrocarbon pollution by enhancement of the aerobic reactions in the subsurface ://.
