“…The addition of small amount of biosurfactant, which increases the bioavailability of PAHs, or some merely toxic chemicals, like salicylic acid, which induce PAHs catabolic operons may enhance biodegradation of PAHs in the environment. It has been seen that organic amendments influence the indigenous microbial community as well as efficiency of bioremediation of PAHs in contaminated soil (Gandolfi et al, 2010; Loick et al, 2012; Lukić et al, 2016; Rein et al, 2016). So adjustment of organic matter content of a polluted site with exogenous addition of compost or other substances like buffalo manure, food and vegetables waste may enhance the bioremediation efficiency of PAH polluted site.…”

Polycyclic aromatic hydrocarbons (PAHs) include a group of organic priority pollutants of critical environmental and public health concern due to their toxic, genotoxic, mutagenic and/or carcinogenic properties and their ubiquitous occurrence as well as recalcitrance. The increased awareness of their various adverse effects on ecosystem and human health has led to a dramatic increase in research aimed toward removing PAHs from the environment. PAHs may undergo adsorption, volatilization, photolysis, and chemical oxidation, although transformation by microorganisms is the major neutralization process of PAH-contaminated sites in an ecologically accepted manner. Microbial degradation of PAHs depends on various environmental conditions, such as nutrients, number and kind of the microorganisms, nature as well as chemical property of the PAH being degraded. A wide variety of bacterial, fungal and algal species have the potential to degrade/transform PAHs, among which bacteria and fungi mediated degradation has been studied most extensively. In last few decades microbial community analysis, biochemical pathway for PAHs degradation, gene organization, enzyme system, genetic regulation for PAH degradation have been explored in great detail. Although, xenobiotic-degrading microorganisms have incredible potential to restore contaminated environments inexpensively yet effectively, but new advancements are required to make such microbes effective and more powerful in removing those compounds, which were once thought to be recalcitrant. Recent analytical chemistry and genetic engineering tools might help to improve the efficiency of degradation of PAHs by microorganisms, and minimize uncertainties of successful bioremediation. However, appropriate implementation of the potential of naturally occurring microorganisms for field bioremediation could be considerably enhanced by optimizing certain factors such as bioavailability, adsorption and mass transfer of PAHs. The main purpose of this review is to provide an overview of current knowledge of bacteria, halophilic archaea, fungi and algae mediated degradation/transformation of PAHs. In addition, factors affecting PAHs degradation in the environment, recent advancement in genetic, genomic, proteomic and metabolomic techniques are also highlighted with an aim to facilitate the development of a new insight into the bioremediation of PAH in the environment.

“…During the 140 days of treatment, temperatures reached thermophilic range in RBM and RFKW, while temperatures in RSS and RFVW were lower and limited to mesophilic range. Based on results of Lukić et al [23], the operating temperature in RBM reached 23,56,56,26,25,26, and 24°C at the day 0, 14, 28, 56, 84, 112, and 140 of experimental activities, respectively. A peak of temperature was reached after 29 days at 56.6°C followed by the cooling and maturation stages of the process.…”

“…Accordingly, in the study of Antizar-Ladislao et al [3] B(a)P removal was not reached through mineralization during composting at 38°C in soil amended with green waste, while in this study B(a)P removal reached even 33 % during composting at lower temperature in soil amended with SS. Nonetheless, temperature profile in RSS was in the range of mesophilic stage throughout the treatment with a peak at 30°C [23]. Further, the equal amount of B(k)F removal, which is also recalcitrant organic pollutant and difficult to be removed from PAH contaminated soil, was reached in RSS, i.e.…”

“…Moreover, the nutrient content of an organic waste has to be considered as an important parameter during the treatment of PAH removal. Actually, Lukić et al [23] have shown that SS contained the lowest C:N ratio and the highest content of soluble fraction and protein compared to BM, FKW, and FVW. Accordingly, the treatment amended with SS was the most successful in PAH removal compared to other three treatments amended with organic wastes which contained a less favorable nutrient content.…”

The removal of polycyclic aromatic hydrocarbons (PAHs) from a spiked OECD (Organisation for Economic Co-operation and Development) artificial soil was investigated. Laboratory-scale thermally insulated bioremediation reactors were used to implement biostimulation strategy of composting. The selected PAHs included anthracene, chrysene, benzo(k)fluoranthene, and benzo(a)pyrene with an initial concentration of 658 mg of USEPA 16 PAHs kg -1 soil (d/w). The contaminants' removal was improved by amending the contaminated soil with four different types of fresh organic waste. After 140 days of incubation, the removal of three-ring and fourring PAHs in all reactors was higher than five-ring PAHs. The reactor displaying a mesophilic phase during bioremediation ended with a removal of 89 and 59 % for threering and four-ring PAHs, respectively. In contrast the reactor displaying a thermophilic phase ended with 71 and 41 % removal for three-ring and four-ring PAHs, respectively. The highest five-ring PAH removal was obtained for reactors with buffalo manure and sewage sludge amendments (40 and 33 %, respectively), while food and kitchen waste and fruit and vegetable waste amendments showed less efficiency (26 and 8 %, respectively). Microtox Ò test data indicated lower toxicity in reactor amended with sewage sludge considering that this setup reached the highest PAH removal and DHA (dehydrogenase activity) compared to others.

“…An important factor is the maturity grade of the organic matter applied; stable compost can accelerate PAH degradation because humic matter facilitates the desorption of the PAH, increasing their availability for microorganisms (Sayara et al 2010). In addition, the application of compost involves nutrients and organic soluble carbon input in soil, which results in biostimulation of soil microorganisms and enhances organic pollutants degradation (Tyagi et al 2011;García-Delgado et al 2015c, b;Lukic et al 2016).…”

This work assesses the suitability of three commercial activated carbons (AC) and their combination with olive mill waste compost (AC+C) as amendments for the remediation of two different contaminated soils.The treatments were applied to a mining soil and their ability to immobilize trace elements was evaluated.Besides, the efficiency of the amendments to degrade and reduce the availability of polycyclic aromatic hydrocarbons (PAH) was investigated in a soil from a wood creosote treatment plant. To this aim, trace elements mobility and PAH degradation and availability were evaluated. Ecotoxicological assays were performed to assess potential toxicity risks in the untreated and the amended soils. In the mining soil, the AC were able to immobilize metals and As but the AC+C treatments were more effective than AC. In the PAH-polluted soil, AC treatments promoted the degradation of high molecular weight PAH but the AC+C amendments further enhanced the degradation of total PAH and reduced the availability of those with 3-rings. The ecotoxicological tests demonstrated an improvement of soil quality when AC and compost were applied together. In conclusion, the co-application of AC and compost reduces the mobility of potentially toxic elements in the polluted mine soil and enhances PAH degradation and reduces PAH availability in the creosote-contaminated soil.
