“…Although several diol isomers are produced from a specific PAH, only a single type of ring cleavage mechanism is reported for each isomer (Pinyakong et al , 2000; Moody et al , 2001). A Gram-positive bacteria species, however, can metabolize 1,2-dihydroxyanthracene through both pathways (Dean-Ross et al , 2001). In the case of Mycobacterium species, ortho -ring cleavage was commonly observed during the transformation of 9,10-dihydroxyphenanthrene and 4,5-dihydroxypyrene (Moody et al , 2001; Vila et al , 2001).…”

“…Diphenic acid is an ortho -cleavage product of 9,10-dihydroxyphenanthrene catalyzed by intradiol dioxygenase (Moody et al , 2001; Kim et al , 2005; Zeinali et al , 2008). Although the possible presence of intradiol cleavage enzyme was expected from the study with anthracene (Dean-Ross et al , 2001) and the ortho -cleavage of 3,4-dihydroxyphenanthrene was recently proposed by Kim et al (2005), such a pathway and the corresponding metabolites have been confirmed. Diphenic acid is one of the most dominant metabolite of phenanthrene by Mycobacterium (Vila et al , 2001).…”

“…Various bioremediation methods of PAHs have been studied (Pradhan et al , 1998; Daane et al , 2001; Parrish et al , 2004). Anthracene, phenanthrene, and pyrene have been used as model PAHs to study various aspects of their degradation by microorganisms, including bioavailability, metabolism, genetics, and compatibility with other remediation methods (Friedrich et al , 2000; Pinyakong et al , 2000; Dean-Ross et al , 2001; Piskonen and Merja, 2004; Stingley et al , 2004). …”

“…Fluoranthene is also considered as a pollution indicator [6]. Biodegradation of PAHs by bacteria is well documented but such knowledge on fungi is limited [7][8][9][10][11]. A variety of bacteria can degrade certain PAHs completely to CO 2 and metabolic intermediates [12,13].…”

The biodegradation of fluoranthene, a high molecular weight polycyclic aromatic hydrocarbon (PAH), was investigated in submerged culture using the wood decaying fungus isolated from forest locality in Gujarat, India. The basidiomycete fungal isolate was found to have an ability to grow on sabaroud dextrose agar containing 50 mgl(-1) of each naphthalene, anthracene, acenaphthene, benzo (a) anthracene, pyrene, flouranthene, carbazole, and biphenyl. The involvement of extracellular fungal peroxidases such as manganese peroxidase (MnP) and laccase (Phenol oxidase) in the degradation of fluoranthene was studied. On the eighth day of incubation 54.09% of 70 mg l(-1) fluoranthene was removed. There after no PAHs removal was observed till the 20th day of the incubation period. The isolate was identified as Pleurotus ostreatus by 18S rRNA, 5.8S rRNA, and partial 28S rRNA gene sequencing. To the best of our knowledge this is the first time Pleurotus ostreatus have been reported to degrade such a high concentration of fluoranthene within much lower time period of incubation. Depletion in the residual fluoranthene in the culture medium was determined by HPLC. Attempts were made to identify the degradation product in the culture medium with the help of FT-IR, NMR, and HPTLC analysis. In the present study positive correlation between fluoranthene degradation and the ligninolytic enzyme (MnP and laccase) production is observed, thus this isolate can play an effective role for bioremediation of PAHs contaminated sites.

“…The ability of bacteria to utilise individual PACs as carbon and energy sources has been well documented (Ahn et al 1999;Cerniglia 1992;Dean-Ross et al 2001). In addition, there are numerous studies into the bacterial community dynamics of petroleum-degrading populations (Stoffels et al 1998;Vinas et al 2005).…”

Enrichment and identification of polycyclic aromatic compound-degrading bacteria enriched from sediment samples

The degradation of polycyclic aromatic compounds (PACs) has been widely studied. Knowledge of the degradation of PACs by microbial populations can be utilized in the remediation of contaminated sites. To isolate and identify PAC-degrading bacteria for potential use in future bioremediation programmes, we established a series of PAC enrichments under the same experimental conditions from a single sediment sample taken from a highly polluted estuarine site. Enrichment cultures were established using the pollutants: anthracene, phenanthrene and dibenzothiophene as a sole carbon source. The shift in microbial community structure on each of these carbon sources was monitored by analysis of a time series of samples from each culture using 16S rRNA polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). Significantly, our findings demonstrate that shifts in the constituent species within each degradative community are directly attributable to enrichment with different PACs. Subsequently, we characterized the microorganisms comprising the degradative communities within each enrichment using 16S rRNA sequence data. Our findings demonstrate that the ability to degrade PACs is present in five divisions of the Proteobacteria and Actinobacteria. By determining the precise identity of the PAC-degrading bacterial species isolated from a single sediment sample, and by comparing our findings with previously published research, we demonstrate how bacteria with similar PAC degrading capabilities and 16S rRNA signatures are found in similarly polluted environments in geographically very distant locations, e.g., China, Italy, Japan and Hawaii. Such a finding suggests that geographical barriers do not limit the distribution of key PAC-degrading bacteria; this finding is in accordance with the Baas-Becking hypothesis "everything is everywhere; the environment selects" and may have significant consequences for the global distribution of PAC-degrading bacteria and their use in bioremediation.
