“…Many different bacterial genera previously isolated from PAH-contaminated sites belong to Sphingomonas (Pinyakong et al, 2000), Paracoccus (Teng et al, 2010), Mycobacterium (Luo, 2008), Comamonas (Goyal and Zylstra, 1996), Pseudomonas (Jacques et al, 2005;Santos et al, 2008), Burkholderia (Juhasz et al, 1997), Janibacter (Zhang et al, 2009), and Sphingobium (Cunliffe and Kertesz, 2006). Enrichment of PAH-degraders is a common phenomenon during the course of PAH biodegradation (Guo et al, 1997;Piskonen et al, 2005).…”

Polycyclic aromatic hydrocarbons (PAHs) are common contaminants in a municipal solid waste (MSW) composting site. Knowledge of changes in microbial structure is useful to identify particular PAH degraders. However, the microbial community in the MSW composting soil and its change associated with prolonged exposure to PAHs and subsequent biodegradation remain largely unknown. In this study, anthracene was selected as a model compound. The bacterial community structure was investigated using terminal restriction fragment length polymorphism (TRFLP) and 16S rRNA gene clone library analysis. The two bimolecular tools revealed a large shift of bacterial community structure after anthracene amendment and subsequent biodegradation. Genera Methylophilus, Mesorhizobium, and Terrimonas had potential links to anthracene biodegradation, suggesting a consortium playing an active role.

“…However, Abd-Elsalam, Hafez, and Hussain (2009), concluded that Escherichia coli, Alcoligenes sp., and Thiobacter subterraneus were efficient isolates for degrading anthracene and phenanthrene. A number of studies have reported extensively on a variety of other bacterial species that have been isolated and noted to posses the ability to utilize PAHs as energy source (Cerniglia, 1992;Kiyohara, Nagao, & Yana, 1982;Sahseverino, Applegate, King, & Sayler, 1993;Zhao, Wu, & Wang, 2009;Zhang et al, 2009;Ling et al, 2011;Zhao et al, 2008). Some microorganisms mainly from the genera Pseudomonas and Mycobacterium have been found capable of transforming and degrading PAHs under aerobic conditions (Mrozik, Piotrowska-Seget, & Łabużek, 2008).…”

The demand for processed petroleum products and agricultural produce has exposed our environment to polycyclic aromatic hydrocarbons (PAHs) contamination. PAHs stick to solid sediments and are ubiquitous including soil, water and air. Their presence in these media creates problems because consuming products obtained from these sources could be deleterious to human health since several of these compounds (benz(a)anthracene, benzo(a)pyrene, chrysene etc) have been implicated in causing tumors in animals and cancer in humans. The present review describes several remediation techniques which are efficient and cost effective in removing PAHs from the environment. Some of these conventional clean-up methods are not only environmental friendly; they also present a novel approach in reducing the ability of PAHs to cause prospective risk to humans and the ecosystem.

“…Similar to other low molecular weight (LMW) PAHs such as naphthalene and phenanthrene, anthracene can be degraded by a wide variety of microorganisms. Isolated bacteria capable of anthracene metabolism include organisms from both Gram-positive (Dean-Ross et al, 2001;Khan et al, 2002;Zeinali et al, 2007;Zhang et al, 2009;Zeng et al, 2010;Ling et al, 2011) and Gram-negative genera (Story et al, 2004;Jacques et al, 2005;Baboshin et al, 2008;Arulazhagan and Vasudevan, 2011;Jin et al, 2012), and several fungi have been described that are capable of transforming anthracene (Wu et al, 2010;Acevedo et al, 2011). However, only recently have culture-independent methods been applied to directly link uncultivated or uncharacterized bacteria to the metabolism of anthracene in contaminated environments.…”

Stable-isotope probing was previously used to identify bacterial anthracene-degraders in untreated soil from a former manufactured gas plant site. However, subsequent pyrosequence analyses of total bacterial communities and quantification of 16S rRNA genes indicated that relative abundances of the predominant anthracene-degrading bacteria (designated Anthracene Group 1) diminished as a result of biological treatment conditions in lab-scale, aerobic bioreactors. This study identified Alphaproteobacterial anthracene-degrading bacteria in bioreactor-treated soil which were dissimilar to those previously identified. The largest group of sequences was from the Alterythrobacter genus while other groups of sequences were associated with bacteria within the order Rhizobiales and the genus Bradyrhizobium. Conditions in the bioreactor enriched for organisms capable of degrading anthracene which were not the same as those identified as dominant degraders in the untreated soil. Further, these data suggest that identification of polycyclic aromatic hydrocarbon-degrading bacteria in contaminated but untreated soil may be a poor indicator of the most active degraders during biological treatment.
