“…The processes of DNA replication and repair were found to be vital for pathogens to effectively colonize the human host ( 34 , 35 ). Many studies have investigated key genes or factors involved in bacterial degradation of PAHs using omics research methods ( 36 – 38 ). Our study also offered a systematic method for filtering important gene categories by using comparative genomic methods.…”

This study provided the latest comparative genomic analysis on Stenotrophomonas maltophilia strains and focused on analyzing their genomic features that allow them to adapt to natural environments. In this study, we set S. maltophilia W18 as a typical PAH-degrading strain of this species. By discussing the genomic adaptative features of degrading PAH, we can predict genomic adaptative features of other S. maltophilia PAH-degrading strains since the core function of this species is stable.

“…23 Additionally, the global and overview maps covered almost all functional pathways of the microorganisms, and played an important role in the process of microbial metabolism of hydrocarbons. 24 Surfactant could not only enhance the bioavailability of PHs, but could also improve the carbon metabolism, which in turn promoted gene expression in the investigated microorganisms. 25 At the same time, the compatibility of the PH components and surfactants with the different bacteria in the mix was different, leading to different responses to the environmental condition and changes in the relative abundance of genetic information.…”

BACKGROUND: Surfactant-enhanced remediation (SER) has been widely applied to remove petroleum hydrocarbon (PH) pollutants, but there are few studies on the mechanism through which surfactants affect the hydrocarbon metabolite ability of microorganism. RESULTS: In this work, combination bacteria and surfactant were selected to remove PH, and the degradation bottleneck concentration of single-bacteria was 10 g L -1 according to the PH degradation rate. However, the degradation efficient of mixed-bacteria was further increased after adding surfactants. Among them, the PH degradation rate of Kocuria rosea + Bacillus odyssey and Microbacterium. sp + B. odyssey at the bottleneck concentration had been respectively reached to 81.58 ± 6.29% with tween-80 and 88.35 ± 7.58% with rhamnolipid. Compared with no surfactant, the relative abundance of global overmaps, amino acid metabolism, and carbohydrate metabolism was increased in adding tween-80 condition. However, when rhamnolipid was added, the relative abundance of ABC transporters, two-component system, and bacteria chemotaxis was clearly increased, indicating an improvement of transportation, absorption, and degradation of PH. Additionally, the gene abundance of alkB and nah was also significantly increased with above condition. Meanwhile, the gene abundance of alkB and nah was also significantly enhanced by above condition.CONCLUSION: This study offers new insights into the functional changes of mixed-bacteria during PH degradation in different surfactant-enhanced systems.

“…Polycyclic aromatic hydrocarbons (PAHs) are a series of harmful substances, which usually exist in petrochemical products, rubber, plastics, lubricating oil, rust-proof oil and organic compounds after incomplete combustion, and are carcinogens in the environment [1][2][3]. In 1979, 16 common PAHs were set on the priority list of pollutants controlled by the Environmental Protection Agency (US EPA), in which fluoranthene (FLT) is a high molecular weight PAHs with four fused rings [4,5].…”

“…Biological methods are often used to remediate groundwater and soil contaminated by FLT [2]. However, they are rarely applied in recent years because of the inferior water solubility of FLT and the difficulty of FLT degradation by microorganism [11][12][13][14][15].…”

In this study, the removal performance and degradation mechanisms of fluoranthene (FLT) in sodium percarbonate (SPC) activated by Fe(II) system were investigated, in which 97.5% removal of FLT could be achieved within 15 min when the concentrations of SPC and Fe(II) were 0.03 and 0.2 mM, respectively. The presence of HO•, O 2 − • and 1 O 2 was demonstrated by probe tests and electron paramagnetic resonance (EPR) detections, and scavenging experiments further proved that the leading reactive oxygen species (ROSs) contributed to FLT removal in SPC/Fe(II) system was HO•. The p-hydroxybenzoic acid analytical result (the reaction product between benzoic acid and HO•) found that 66.5% of HO• in the system was produced in the first 5 min of the reaction. Several intermediates of FLT were detected by GC-MS and three probable FLT degradation pathways were proposed. The effect of SPC dosage, Fe(II) concentration, initial solution pH and inorganic anions (Cl − and HCO 3 − ) on FLT degradation were assessed. 90.3% FLT was removed in actual groundwater when the dosages of SPC and Fe(II) were 0.15 and 1.0 mM, respectively. This result indicated that FLT removal could be improved by elevating the dosages of SPC and Fe(II) and adjusting the initial solution pH to 5.0, confirming the effective removal of FLT in actual groundwater in SPC/Fe(II) system. Overall, this study demonstrated that SPC/Fe(II) system has broad prospective in the remediation of FLT-contaminated groundwater.
