“…Thus, halophilic microorganisms are the best alternatives to overcome this problem (Oren et al, 1992; Garcia et al, 2005; Fathepure, 2014; Kostka et al, 2014). In the last decade there has been an increasing interest in the development and optimization of bioremediation processes via halophiles to deal with hypersaline environments that are contaminated with organic pollutants (Margesin and Schinner, 2001a; Mellado and Ventosa, 2003; Peyton et al, 2004; Garcia et al, 2005; Cui et al, 2008; Mnif et al, 2009; Zhao et al, 2009; Bonfa et al, 2011; Smith et al, 2013; Fathepure, 2014; Kappell et al, 2014; Lamendella et al, 2014; Singh et al, 2014; Thomas et al, 2014). Some halophiles that have shown PAHs degrading property are depicted in Supplementary Table S1.…”

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.

“…The strain D15-8W degrades naphthalene, phenanthrene or anthracene as the sole source of carbon. Bonfá et al [144] have isolated several strains of Haloferax that degrade a mixture of the PAHs including naphthalene, anthracene, phenanthrene, pyrene and benzo[a] anthracene. Extremely halophilic archaeal strains of Haloferax, Halobacterium, and Halococcus isolated from a hypersaline coastal area of the Arabian Gulf not only degraded crude oil and n-octadecane as the carbon sources, but also grew on phenanthrene [111].…”

This article is a state-of-the-art review on the aerobic degradation of petroleum components that are commonly found in the environment. Numerous microorganisms have been isolated and their phylogeny and metabolic capacity to degrade a variety of aliphatic and aromatic hydrocarbons have been demonstrated. This review focuses on recent progress on how microbes degrade hydrocarbons and heteroaromatic components of petroleum contaminants directed towards better understanding of the aerobic degradation processes and their exploitation for bioremediation. The phylogenetic diversity of the oil-degrading microbes was also discussed.
