“…Sediments, the primary reservoir for hydrophobic contaminants, are natural sinks and environmental reservoirs for PAHs in the aquatic environment, and they offer an irreplaceable aid in the development of sediment quality criteria (Santana et al, 2015). Therefore, a comprehensive study of PAH behavior in aquatic environments has been of great concern because riverine and estuarine areas receive considerable amounts of pollutant inputs from terrestrial drainage, which could potentially threaten aquatic organism (Tavakoly Sany et al, 2014;Zhang et al, 2015;Dudhagara et al, 2016).…”

“…Last few years, PAHs are compounds of intense public concern due to their thermodynamic stability of benzene moiety and potentially deleterious effects on human, environment and ecological health. The cleanup of such type of pollutant using innate metabolic capability of bacteria is a promising approach for bioremediation of recalcitrant compound [1,2]. Microbial degradation can be increased by manipulating nutritional requirements.…”

International Journal of Marine Biology and Research Open Access Research Article the variables can eliminate these limitations of "one factor at time" approach. Statistical method has several advantages as being rapid, reliable, less expensive, screening of number of variables, understanding of effect of variable at various coded level [3]. Numbers of statistical models are available amongst them Plackett-Burman (PB) and Response Surface Methodology (RSM) is most widely used statistical models. Two level fractional factorial designs (PB design) is used for the screening of the variable with small number of experimental runs instead of using more extensive factorial design, which would furnish more detail explanation [4]. The present paper discusses screening of suitable medium components for degradation of anthracene by Sphingobium yanoikuyae strain ANT3D using Plackett-Burman design. Materials and Methods Organism and Medium Multiple PAHs degrading isolate S. yanoikuyae strain ANT3D was selected for optimization of BH medium components as MgSO 4 , CaCl 2 , KH 2 PO 4 , K 2 HPO 4 , NH 4 NO 3 , and FeCl 3. The S. yanoikuyae strain ANT3D was routinely grown on BH medium amended with anthracene at concentration of 50 mg/ L and stored at 4°C until use [5]. Enrichment and isolation of PAHs degrading bacteria using selective media Soil samples were collected from crude oil contaminated saline sites near Gulf of Kutch, Jamnagar coast (latitude 22°34'17.50" °N, 70°10'53.00" °E, longitude) Gujarat, India. Isolation of PAHs degrading bacteria was executed by using various selective media and techniques as described below: Nagel and Andreesen's (NA) [6] and Bushnell-Hass (BH) [7] media were used for enrichment of PAHs degrading bacteria from crude oil polluted marine sediment samples. For this, 1g of polluted sediment samples were added to 10 mL BH medium in test tube and vortexed for 1 min.

“…Due to their widespread presence in the air, soil and sediments, they have attracted a lot of attentions in different studies. These compounds should be eliminated from the environment because evidences indicate that PAHs mixtures are teratogenic, mutagenic and carcinogenic to humans [3]. Different methods such as biological, thermal, physical, chemical and solidification can be applied for soil remediation [4].…”

BackgroundBiological methods of polycyclic aromatic hydrocarbons (PAH) contamination elimination typically involve the transformation of contaminants to non-toxic materials by microorganisms and plants and appear to be the most effective methods available.MethodsIn this study, Bacillus licheniformis and Bacillus mojavensis isolated from oil-contaminated soils were inoculated onto Festuca arundinacea seeds before planting in the pot and 3 weeks after planting by syringe injection into the rhizospheric zone in order to study the elimination of PAHs from Festuca’s rhizosphere in the greenhouse. Some physical and chemical properties of the soil, PAH concentrations, seeds germination percentage, root and shoot biomasses of the treated samples were examined.ResultsThe results showed that the treated samples inoculated with both bacteria had a significantly higher percentage of seed germination and root and shoot biomass compared to other treatments. The concentration of some PAHs reduced significantly (Pvalue < 0.05) in the rhizosphere of the treated samples inoculated with both bacteria compared to in contaminated soils. Concentrations of some PAHs (eg. Naphthalene, Phenanthrene, Benzo[a]anthracene and Dibenzo[a,h]anthracene) even reached below the detection limit of the method. The PAHs concentrations in the treated samples inoculated with bacteria was decreased significantly (Pvalue < 0.05). Therefore, the results showed the high efficiency of the Festuca and bacterial inoculation in eliminating PAHs from the soil.ConclusionAccording to the results, the partnership of Festuca with B. licheniformis and B. mojavensis isolates displayed positive effect on PAHs dissipation and can be effective cleanup technology with high performance.
