“…It has been shown that both metal dosage and exposure time yielded a significant effect on the ability of removal of low molecular weight PAHs like fluorene and phenanthrene by the alga, whereas for high molecular weight PAHs like fluoranthrene, pyrene and BaP, the removal efficiency was not affected by the presence of metals. Patel et al (2016) recently reported the biodegradation of anthracene and pyrene by Anabaena fertilissima ( Patel et al, 2016 ), while Takáčová et al (2014) reported the biodegradation of BaP by the microalgae Chlorella kessleri . Removal and transformation of seven high molecular weight PAHs in water was reported by live and dead cells of a freshwater microalga, Selenastrum capricornutum under gold and white light irradiation.…”

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.

“…Malik and Ahmed, (2012) studied the removal of petroleum hydrocarbons using a bacterial consortium and found a 51 to 68% degradation efficiency on polyaromatic fractions (anthracene, naphthalene, phenanthrene and pyrene) with a total concentration of 14784 ppb after 24 days (Malik and Ahmed, 2012). Also, Patel et al, (2016) used the strain Anabaena fertilissima for 16 days and found a removal of 46% for anthracene and 33% for pyrene, at concentrations of 5 mg L -1 and 3 mg L -1 , respectively (Patel et al, 2016). Obayori et al, (2014) studied the degradation of two different grades of engine oil namely SAE 40W and SAE 20W 50 by Pseudomonas aeruginosa LP5 and observed higher degradation rate in the first 12 days than the last 9 days.…”

This study investigates motor oil (3, 5, 7.5 and 10% (v v)) as a sole carbon source for the production of Alcanivorax borkumensis in shake flasks and a 5 L bench-scale fermenter in comparison to the standard media. Shake flask studies showed a significant and higher cell growth (p=0.000038), lipase (p = 0.006900) and alkane hydroxylase production (p = 0.000921) by Alcanivorax borkumensis when motor oil was used as the substrate. Based on Tukey post-hoc tests, 5% motor oil concentration was selected as the optimal substrate concentration. The 5 L fermenter experiments conducted using motor oil at 5% (v v) concentration, under controlled conditions exhibited significant and higher alkane hydroxylase and lipase activities (55.6 U mL (p = 0.018418) and 208.30 U mL (p = 0.020087), respectively) as compared with those of motor oil at 3% (v v) and n-hexadecane at 3% (v v) concentration which was used as control. Cell growth was significantly higher when motor oil (3 or 5%) was used as a substrate (p = 0.024705). Enzymatic degradation tested on two different polycyclic aromatic hydrocarbons (PAHs) contaminated groundwaters showed 37.4% removal after 5 days with a degradation rate of 196.6 ppb day and 82.8% removal after 10 days with a degradation rate of 217.54 ppb day for the 1st site and an almost complete biodegradation with 95% removal and 499.02 ppb day removal rate after only 5 days for the 2nd site.

The objective of this study was to analyze the effect of two grass species, i.e. red fescue (Festuca rubra) and tall fescue (F. arundinacea), on the functional and genetic diversity of soil-dwelling microorganisms and on the enzymatic activity of soil not polluted and polluted with diesel oil. Grasses were examined for their effectiveness in accelerating degradation of PAHs introduced into soil with diesel oil. A growing experiment was conducted in Kick-Brauckman pots. The soil not polluted and polluted with diesel oil (7 cm3 kg-1 d.m.) was determined for the count of bacteria, colony development index, ecophysiological diversity index, functional diversity (using Biolog system), genetic diversity of bacteria (using NGS), enzymatic activity, and content of hydrocarbons. Study results demonstrated disturbed homeostasis of soil. The toxic effect of diesel oil on grasses alleviate with time since soil pollution. The yield of the first swath of red fescue decreased by 98% and that of tall fescue by 92%, whereas the yields of the second swath decreased by 82% and 89%, and these of the third swath by 50% and 47%, respectively. Diesel oil diminished also the functional and genetic diversity of bacteria. The use of grasses significantly decreased contents of C6-C12 (gasoline total), C12-C35 mineral oils, BTEX (volatile aromatic hydrocarbons), and PAHs in the soil, as well as enabled restoring the microbiological equilibrium in the soil, and increased functional and genetic diversity of bacteria. For this reason, both analyzed grass species, i.e. Festuca rubra and F. arundinacea, may be recommended for the remediation of soil polluted with diesel oil.
