“…It is a complex mixture of hydrocarbons, many of which are classified as mutagenic, carcinogenic and teratogenic ( Liao et al, 2014 ; Schwarz et al, 2019 ). Oil hydrocarbons can be classified in four groups according with their solubility in organic solvents and water ( Han et al, 2018 ). These groups are described as: (i) saturated hydrocarbons (or alkanes, or aliphatic), including all the n- and branched alkanes and cycloparaffins, (ii) aromatic hydrocarbons, including monoaromatics such as BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) and polycyclic aromatic compounds (PAHs), (iii) resins, are compounds that contains sulfur, oxygen and nitrogen and that are dissolved in oil such as quinolines, pyridines, amides and sulfoxides, and (iv) asphaltenes, consisting of aggregates of molecules with naphthenic rings and condensed aromatic connected by paraffin chains ( Gentili et al, 2006 ; Costa et al, 2012 ; Wu et al, 2013 ; Abdel-Shafy and Mansour, 2016 ; Varjani, 2017 ; Shahsavari et al, 2019 ).…”

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.

“…On the other hand, the worldwide attention has been drawn to the sulfur content of diesel fuel as after combustion, the sulfur compounds in the fuel are converted to sulfur oxides (SOx), which cause acid rain and air pollution, as well as catalyst toxicity. Governments worldwide have noticed these concerns and have imposed new strict environmental regulations on fuel sulfur levels to minimize SOx emissions (15,16). Several approaches have been investigated to remove those heterocyclic sulfur compounds (14,(17)(18)(19)(20)(21)(22).…”

“…Indonesia is one of the world's oil producer countries that is able to produce oil up to 801.4 thousand barrels per day in 2017. Petroleum is a dark, sticky and viscous liquid which is composed of complex compound of hydrocarbons and non-hydrocarbons (Vieira et al 2007;Han et al 2018). Organic compounds that dominate the composition of petroleum are aliphatic and aromatic hydrocarbons (Rajaei et al 2013).…”

Abstract. Sari MA, Retnaningrum E. 2019. Hydrocarbon degradation by bacteria from rhizospheres of Imperata cylindrica at oil mining site in Wonocolo, Bojonegoro, Indonesia. Biodiversitas 20: 3422-3429. High oil mining activities cause environmental pollution at the oil mining site. Petroleum spills and waste to the river flow cause blackish discoloration along the riverbank and also some types of plants die. The utilization of rhizospheric bacteria (rhizobacteria) as a bioremediation agent is considered as appropriate for reducing petroleum contaminants. The purposes of this study were to analyze the ability of hydrocarbon degradation by selected rhizobacteria isolates, to identify molecularly and analyze the genetic relationship of hydrocarbon-degrading rhizobacteria based on 16S rRNA gene sequencing. The rhizobacteria of cogongrass (Imperata cylindrica L.) were isolated from oil mining site in Wonocolo, Kedewan, Bojonegoro, East Java, Indonesia. The 5 isolates of rhizobacteria were then cultured on Bushnell-Haas Mineral Salt (BHMS) medium with the addition of 0.015% crude oil for analyzing their growth based on their cell densities using the Total Plate Count method. The optimal rhizobacteria growth obtained (MTMW2 isolate) was selected and further analysed its ability for hydrocarbon degradation through measuring of Total Petroleum Hydrocarbon (TPH). Its rhizobacteria were then identified using 16S rRNA gene sequencing. The MTMW2 isolate revealed specific growth rate of 0.14 in BHMS medium with the addition of 0.015% crude oil. After 10 days of incubation, the isolates could degrade Total Petroleum Hydrocarbon in the medium as much as 96.1%. The results of molecular identification and phylogenetic tree construction showed that MTMW2 isolate was identified as Pseudomonas aeruginosa.
