Aromatic hydrocarbons like benzene, toluene, xylene, and ethylbenzene (BTEX) can escape into the environment from oil gas operations manufacturing industries posing significant health risks to humans wildlife. Unlike conventional clean-up methods used, biological approaches such as bioremediation provide a more energy labour-efficient environmentally friendly option for sensitive areas nature reserves cities, protecting biodiversity public health. BTEX contamination is often concentrated in subsurface of these locations where oxygen rapidly depleted, biodegradation relies on anaerobic processes. Thus, it critical understand characteristics has not been explored major extent. This review presents novel insights degradation mechanisms under conditions detailed description interconnection between them. follow four activation mechanisms: hydroxylation, carboxylation, methylation, fumarate addition. Hydroxylation one that explains transformation benzene phenol, toluene benzyl alcohol or p-cresol, 1-phenylethanol. Carboxylation benzoate thought be primary mechanism benzene. Despite being poorly understood, methylation also reported. Moreover, addition most widely reported mechanism, present ethylbenzene, xylene degradation. Further research efforts are required better elucidate new current alternative catabolic pathways. Likewise, comprehensive analysis enzymes involved well development advance tools omic reveal bottlenecks steps create effective on-site strategies address pollution.

Identification of Potentially Toxic Transformation Products Produced in Polycyclic Aromatic Hydrocarbon Bioremediation Using Suspect and Non-Target Screening Approaches

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: April 10, 2025

Polycyclic aromatic hydrocarbons (PAHs) are a class of ubiquitous environmental contaminants that can be remediated through physical, chemical, or biological means. Treatment strategies lead to the formation PAH-transformation products (PAH-TPs) that, despite having potential for adverse ecological and human health effects, unregulated understudied in monitoring remediation. Unavailability reference standards PAH-TPs limits ability identify by targeted methods. This study utilized suspect nontarget screening approaches produced bacterial culture, Rhodococcus rhodochrous ATCC 21198, using liquid chromatography-high resolution mass spectrometry. Open-source tools were used predict biotransformation products, PAH-TP structures from spectra, estimate hazards PAH-TPs. The workflow developed this allowed tentative identification 16 (confidence levels 2a 3), seven which not previously detected analysis. Several new transformation pathways our pure culture suggested PAH-TPs, including carboxylation, sulfonation up three hydroxylation reactions. A computational toxicity assessment indicated shared many hazard characteristics with their parent compounds, genotoxicity endocrine disruption, highlighting importance considering future PAH studies.
