“…Application of thermotolerant and thermophilic bacteria for PAH degradation is beneficial, as elevated temperature causes increased diffusion of PAHs by decreasing viscosity, ultimately increasing the bioavailability of PAHs (Mehetre et al, 2019). Over the last decade, bacterial community analysis (Muangchinda et al, 2018;Yang et al, 2020), biochemical pathways in bacteria for PAH degradation (Chen et al, 2016;Vaidya et al, 2017), degradation-associated bacterial genes (Peng T. et al, 2018;Sangkharak et al, 2020), enzyme systems (Chen et al, 2016;Wu et al, 2020), and gene regulation of PAH degradation processes (Kan et al, 2020;Wu et al, 2020) have been researched enormously.…”

“…According to correlation statistics, all positively correlated taxa can be utilized in PAH bioremediation as they are resistant to PAHs and, conversely, negatively correlated taxa are sensitive to PAHs (Redfern et al, 2019). Muangchinda et al (2018) reported changes in the bacterial communities between original seawater and mixed PAH-degrading consortium SWO (developed from the same sea water) using high-throughput 16S rRNA gene sequencing. They found an increased proportion of Proteobacteria and decreased proportion of Bacteroidetes in consortium SWO along with lower Shannon and Simpson indices.…”

Polycyclic aromatic hydrocarbons (PAHs) are widespread across the globe mainly due to long-term anthropogenic sources of pollution. The inherent properties of PAHs such as heterocyclic aromatic ring structures, hydrophobicity, and thermostability have made them recalcitrant and highly persistent in the environment. PAH pollutants have been determined to be highly toxic, mutagenic, carcinogenic, teratogenic, and immunotoxicogenic to various life forms. Therefore, this review discusses the primary sources of PAH emissions, exposure routes, and toxic effects on humans, in particular. This review briefly summarizes the physical and chemical PAH remediation approaches such as membrane filtration, soil washing, adsorption, electrokinetic, thermal, oxidation, and photocatalytic treatments. This review provides a detailed systematic compilation of the eco-friendly biological treatment solutions for remediation of PAHs such as microbial remediation approaches using bacteria, archaea, fungi, algae, and co-cultures. In situ and ex situ biological treatments such as land farming, biostimulation, bioaugmentation, phytoremediation, bioreactor, and vermiremediation approaches are discussed in detail, and a summary of the factors affecting and limiting PAH bioremediation is also discussed. An overview of emerging technologies employing multi-process combinatorial treatment approaches is given, and newer concepts on generation of value-added by-products during PAH remediation are highlighted in this review.

“…Currently, the genetic basis of the catabolic pathways of the various PAHs remains poorly understood. Thus, the use of recent approaches as meta-taxonomics and metagenomics offers great potential to contribute with information to elucidate PAH degradation pathways ( Brennerova et al, 2009 ; Nyyssönen et al, 2009 ; Abbai and Pillay, 2013 ; Uhlik et al, 2013 ; Mason et al, 2014 ; Xu et al, 2014 ; El Amrani et al, 2015 ; Loviso et al, 2015 ; Ma B. et al, 2015 ; Techtmann and Hazen, 2016 ; Zafra et al, 2016 ; Duarte et al, 2017 ; Muangchinda et al, 2018 ; Tiralerdpanich et al, 2018 ; Wilhelm et al, 2018 ; Xu et al, 2018 ; Hidalgo et al, 2019 ). From now on, we will present the information available from several studies carried out to explore PAH biodegradation in natural or impacted environments rich in hydrocarbons.…”

“…There are many complete or almost complete sequenced genomes of cultured microorganisms which have functional potential metabolism for hydrocarbon degradation ( Ghosal et al, 2016 ). Nevertheless, scientists have long known that only about 1% of the total microbial communities has been cultivated ( Hugenholtz and Pace, 1996 ; Hugenholtz et al, 1998 ) and advances in the use of -omics techniques, like genomics, proteomics and metabolomics, in bioremediation studies have helped to improve the understanding of biodegradation processes ( Brennerova et al, 2009 ; Nyyssönen et al, 2009 ; Abbai and Pillay, 2013 ; Uhlik et al, 2013 ; Mason et al, 2014 ; Xu et al, 2014 , 2018 ; El Amrani et al, 2015 ; Loviso et al, 2015 ; Ma B. et al, 2015 ; Techtmann and Hazen, 2016 ; Zafra et al, 2016 ; Duarte et al, 2017 ; Muangchinda et al, 2018 ; Tiralerdpanich et al, 2018 ; Wilhelm et al, 2018 ; Hidalgo et al, 2019 ). Sequencing metagenomes from diverse contaminated environments (soils, aquifers, seawater) can help to providing insights into the ecology of the dominant and rare members and their functional potential for transformation of pollutant molecules such as PAHs and other hydrocarbons ( Blow, 2008 ; Ghosal et al, 2016 ).…”

Metagenomic Insights Into the Mechanisms for Biodegradation of Polycyclic Aromatic Hydrocarbons in the Oil Supply Chain

et al. 2020

Petroleum is a very complex and diverse organic mixture. Its composition depends on reservoir location and in situ conditions and changes once crude oil is spilled into the environment, making the characteristics associated with every spill unique. Polycyclic aromatic hydrocarbons (PAHs) are common components of the crude oil and constitute a group of persistent organic pollutants. Due to their highly hydrophobic, and their low solubility tend to accumulate in soil and sediment. The process by which oil is sourced and made available for use is referred to as the oil supply chain and involves three parts: (1) upstream, (2) midstream and (3) downstream activities. As consequence from oil supply chain activities, crude oils are subjected to biodeterioration, acidification and souring, and oil spills are frequently reported affecting not only the environment, but also the economy and human resources. Different bioremediation techniques based on microbial metabolism, such as natural attenuation, bioaugmentation, biostimulation are promising approaches to minimize the environmental impact of oil spills. The rate and efficiency of this process depend on multiple factors, like pH, oxygen content, temperature, availability and concentration of the pollutants and diversity and structure of the microbial community present in the affected (contaminated) area. Emerging approaches, such as (meta-)taxonomics and (meta-)genomics bring new insights into the molecular mechanisms of PAH microbial degradation at both single species and community levels in oil reservoirs and groundwater/seawater spills. We have scrutinized the microbiological aspects of biodegradation of PAHs naturally occurring in oil upstream activities (exploration and production), and crude oil and/or by-products spills in midstream (transport and storage) and downstream (refining and distribution) activities. This work addresses PAH biodegradation in different stages of oil supply chain affecting diverse environments (groundwater, seawater, oil reservoir) focusing on genes and pathways as well as key players involved in this process. In depth understanding of the biodegradation process will provide/improve knowledge for optimizing and monitoring bioremediation in oil spills cases and/or to impair the degradation in reservoirs avoiding deterioration of crude oil quality.

“…O petróleo é uma mistura complexa constituída de hidrocarbonetos saturados, hidrocarbonetos aromáticos (HPAs), resinas e asfaltenos, sendo os HPAs considerados perigosos devido a seus efeitos tóxicos, mutagênicos e carcinogênicos, sendo o solo um dos receptores desses contaminantes (Muangchinda et al, 2018). Diversos microrganismos são capazes de oxidar componentes do petróleo aerobicamente.…”

RESUMO-O presente estudo avaliou a biorremediação de um solo multicontaminado real, oriundo de uma região adjacente a uma refinaria. Os ensaios foram feitos em escala de microcosmos visando aplicação futura em biorreator de fase sólida. Foi utilizada a técnica de bioestimulação aliada ao uso dos surfatantes sintéticos TWEEN 80 e TRITON X-100 e do biossurfatante JBR210. Os melhores resultados de remoção de HTP foram obtidos para os ensaios contendo o surfatante sintético TWEEN 80 (concentração 0,1mg/g de solo), sendo este de 28,5%, seguido pelo uso do TRITON X-100 (concentração de 0,1mg/g de solo), alcançando 24,75%.
