“…Typical treatments include Fenton's reagent with hydrogen peroxide and ferrous iron, the less acidic modified Fenton's reagent, permanganate, persulfate, and ozone injection (Table 1). A number of review articles provide insight into the chemistry and proper application of oxidation regimens (Gates and Siegrist 1995;Kubal et al 2008;Rivas 2006;Seol et al 2003;Tsai et al 2008;Watts and Teel 2005). ISCO has been successfully used to oxidize and thus lower the concentration of petroleum-derived hydrocarbons (total petroleum hydrocarbons, TPH, Crimi and Taylor 2007;Gates and Siegrist 1995;Huang et al 2005;Jung et al 2005;Lee and Kim 2002), polyaromatic hydrocarbons (PAH; Lee and Hosomi 2001;Masten and Davies 1997;Nam et al 2001;Watts et al 2002), and chlorinated hydrocarbons (Huang et al 1999(Huang et al , 2005Hunkeler et al 2003;Northup and Cassidy 2008;Ormad et al 1994;Schnarr et al 1998;Siegrist et al 1999;Vella and Veronda 1993;Watts et al 1990).…”

Purpose In order to provide highly effective yet relatively inexpensive strategies for the remediation of recalcitrant organic contaminants, research has focused on in situ treatment technologies. Recent investigation has shown that coupling two common treatments-in situ chemical oxidation (ISCO) and in situ bioremediation-is not only feasible but in many cases provides more efficient and extensive cleanup of contaminated subsurfaces. However, the combination of aggressive chemical oxidants with delicate microbial activity requires a thorough understanding of the impact of each step on soil geochemistry, biota, and contaminant dynamics. In an attempt to optimize coupled chemical and biological remediation, investigations have focused on elucidating parameters that are necessary to successful treatment. In the case of ISCO, the impacts of chemical oxidant type and quantity on bacterial populations and contaminant biodegradability have been considered. Similarly, biostimulation, that is, the adjustment of redox conditions and amendment with electron donors, acceptors, and nutrients, and bioaugmentation have been used to expedite the regeneration of biodegradation following oxidation. The purpose of this review is to integrate recent results on coupled ISCO and bioremediation with the goal of identifying parameters necessary to an optimized biphasic treatment and areas that require additional focus. Conclusions and recommendations Although a biphasic treatment consisting of ISCO and bioremediation is a feasible in situ remediation technology, a thorough understanding of the impact of chemical oxidation on subsequent microbial activity is required. Such an understanding is essential as coupled chemical and biological remediation technologies are further optimized.

“…It is, however, very important to find rapid and effective solutions able to sanitize the interested areas from PAH pollutants in order to reduce the potential health risks (Krajčovičová & Eschenroeder 2007;Jennings 2012). Different kinds of chemical strategies are currently applied to clean the soil from PAH contaminations, of which the chemical oxidation using oxidants such as ozone, hydrogen peroxide, permanganate, and persulphate seems to be a promising technique (Bissey et al 2006;Rivas 2006;Ferrarese et al 2008).…”

Different abandoned industrial areas contaminated by polycyclic aromatic hydrocarbons (PAHs) are present in Slovakia. These environmental burdens are very dangerous to the health of human and environment. The bioremediation, based on the use of hydrocarbons degrading microorganisms, is a promising strategy to sanitize these polluted sites. The aim of this investigation was to assess the bacterial diversity of a PAHs-contaminated soil and to select the potential hydrocarbonoclastic bacteria which can be used for different bioremediation approaches. The bacterial strains were isolated on minimal medium agar supplemented with a mixture of PAHs. Seventy-three isolated strains were grouped by ribosomal interspacer analysis in 15 different clusters and representatives of each cluster were identified by 16S rRNA sequencing. The PAHs degradation abilities of all bacterial isolates were estimated by the 2,6-dichlorophenol indophenol assay and by their growth on minimal broth amended with a mixture of PAHs. Different kinds of strains, members of the genus Pseudomonas, Enterobacter, Bacillus, Arthrobacter, Acinetobacter and Sphingomonas, were isolated from the contaminated soil. Four isolates (Pseudomonas putida, Arthrobacter oxydans, Sphingomonas sp. and S. paucimobilis) showed promising PAHs-degrading abilities and therefore their possible employing in bioremediation strategies.

“…[9] has reported that soil pollution influences the activities of enzymes in the soil. The soluble compounds in diesel have been reported to be toxic to aquatic organisms, other animals and human beings [10], [11], [12], [13]. Bioistimulation involves nutrient enhancement of microbial breakdown of organic waste [14].Natural manure such as poultry manure,compost and artifitial manure such as fertilizer have been reported to improve microbial degradation of organic wastes [15], [16], [3].…”
