Aromatic compounds are among the most prevalent and persistent pollutants in the environment. Petroleum-contaminated soil and sediment commonly contain a mixture of polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatics. Aromatics derived from industrial activities often have functional groups such...
Here, we describe three alternative strategies used by microorganisms to degrade aromatic compounds. All three of these methods involve the use of CoA thioesters and ring cleavage by hydrolysis. However, these strategies are based on different ring activation mechanisms that consist of either formation...
Utilized in the bacterial degradation of toxic aromatic compounds, the enzyme’s crystal structure indicates that intermediates are shuttled directly between active sites through a hydrophobic intermediary channel, providing an unreactive environment in which to move the reactive acetaldehyde intermediate fro...
32. Based on the molecular formulas derived from FT-ICR MS, four types of functional compounds with declining photoreactivity and aromaticity, including combustion-derived polycyclic aromatics (CA), vascular plant-derived polyphenols (Pol.), highly unsaturated and phenolic compounds (Uns.) and ...
Sugars, alcohols, (di-)carboxylic acids, amino acids and aromatic compounds were not fermented and no external electron acceptors were used. Strain VenChi2(T) is a Gram-negative, strictly anaerobic, coccoid rod; it does not employ the classical hydroaromatic pathway of aerobic bacteria for the...
This review focuses on bacterial degradation pathways of selected aromatic compounds. Catabolic pathways of naphthalene, fluorene, phenanthrene, fluoranthene, pyrene, and benzo[a]pyrene are described in detail. Bacterial catabolism of the heterocycles dibenzofuran, carbazole, dibenzothiophene, and di...
2.3. Photocatalytic Degradation of Aromatic Compounds The photocatalytic activities of the S-TiO2 photocatalysts were evaluated in degradation experiments with three water-soluble aromatic compounds: phenol (PhOH, Chart 1 I), 4,4′-isopropylidenebisphenol (BPA, Chart 1 II), and 4,4′-isopropylidenebi...

Herein, a series of electron-Fenton catalysts with three size-dependent Co species (single atom, cluster, nanoparticle) were designed for electro-Fenton degradation of aromatic compounds. In the heterogeneous-homogeneous coupled electro-Fenton (HHC-EF) system, the Co-N bond accelerated electron transf...
