“…Hydrogenophaga is known as an aerobic dechlorinating bacterium [44] that hydrogen can be used as electron donor for its autotrophic growth [45]. Hydrogenophaga strains have been isolated from textile wastewater treatment plants, PAH-contaminated river sediments, and haloaromatic-contaminated soils, con rming they are able to degrade various organic pollutants, such as 4-aminobenzenesulfonate, 4-chlorobenzoate, and high molecular weightpolycyclic aromatic hydrocarbons [46][47][48]. In addition, the abundance of Methyloversatilis and Ancylobacter increased under PFOA exposure.…”

The extensive application of per uoroalkyl and poly uoroalkyl substances (PFASs) causes their frequent detection in various environments. Nevertheless, the effects of PFASs exposure on environmental microorganisms still remain unknown. In current work, two typical PFASs, per uorooctanoic acid (PFOA) and per uorooctanesulfonic acid (PFOS), are selected to investigate their long-term effects on soil microbes. Microbial community structure and diversity were investigated by high-throughput sequencing and multiple statistical methods. Under 90-days of exposure, PFAS treatments increased the alphadiversity of soil microbial communities with PFOS treatment, followed by PFOA treatment. The long-term exposure of PFASs substantially changed the compositions of soil microbial communities. The most abundant phylum Proteobacteria decreased from 82.9% (without amended PFASs) to 62.1% (with PFOA treatment) and 77.8% (with PFOS treatment). As a comparison, the relative abundance of Bacteroidetes, Chloro exi, Acidobacteria, and Ignavibacteriae increased in the PFOA or PFOS groups. Comparative cooccurrence networks were constructed to investigate the biotic interactions in the two treatments. It was found that most taxonomy nodes in the PFOA and PFOS networks were associated with the genus Hydrogenophaga and Pseudoxanthomonas, respectively. The LEfSe analysis identi ed a set of core taxonomies (e.g., Azospirillum, Methyloversatilis, Ancylobacter, Hydrogenophaga, and Methylomonas) in the soil microbial communities and suggested their different preferences to PFAS exposures. Functional gene prediction suggested that the microbial metabolism processes, such as nucleotide transport and metabolism, cell motility, carbohydrate transport and metabolism, energy production and conversion, and secondary metabolites biosynthesis transport and catabolism, might be signi cantly inhibited under PFAS exposure, which may further affect soil ecological services.

“…All three isolates possessed putative catA genes encoding catechol dioxygenase, which may be involved not only in catechol metabolism, but also in CC degradation [ 17 , 57 ]. The catA genes of 19CS4-2 and 19C6 were located upstream of the cbeABCD gene cluster and probably formed an operon ( Figure 5 a).…”

“…3-Chlorobenzoate (3-CBA) is a halogenated compound used as a raw material for producing fertilizers and for several applications in industry. In addition, 3-CBA can be produced as a dead-end product when polychlorinated biphenyls (PCB) are metabolized by microorganisms and 3-CBA degradation is important for complete PCB degradation [ 17 ]. The degradation of 3-CBA is carried out mainly through microbial metabolism.…”

The compound 3-chlorobenzoate (3-CBA) is a hazardous industrial waste product that can harm human health and the environment. This study investigates the physiological and genetic potential for 3-chlorobenzoate (3-CBA) degradation. Six 3-CBA Gram-negative degraders with different degradation properties belonging to the genera Caballeronia, Paraburkholderia and Cupriavidus were isolated from the soil. The representative strains Caballeronia 19CS4-2 and Paraburkholderia 19CS9-1 showed higher maximum specific growth rates (µmax, h−1) than Cupriavidus 19C6 and degraded 5 mM 3-CBA within 20–28 h. Two degradation products, chloro-cis,cis-muconate and maleylacetate, were detected in all isolates using high-performance liquid chromatography and mass spectrometry. Genomic analyses revealed the presence of cbe and tfd gene clusters in strains 19CS4-2 and 19CS9-1, indicating that they probably metabolized the 3-CBA via the chlorocatechol ortho-cleavage pathway. Strain 19C6 possessed cbe genes, but not tfd genes, suggesting it might have a different chlorocatechol degradation pathway. Putative genes for the metabolism of 3-hydroxybenzoate via gentisate were found only in 19C6, which utilized the compound as a sole carbon source. 19C6 exhibited distinct characteristics from strains 19CS4-2 and 19CS9-1. The results confirm that bacteria can degrade 3-CBA and improve our understanding of how they contribute to environmental 3-CBA biodegradation.

A novel bacterial strain was isolated from industrially contaminated waste water. In the presence of crude oil, this strain was shown to reduce the rate of total petroleum hydrocarbons (TPH) up to 97.10% in 24h. This bacterium was subsequently identified by 16S rRNA gene sequence and affiliated to the Serratia genus by the RDP classifier. Its genome was sequenced and annotated, and genes coding for catechol 1,2 dioxygenase and naphthalene 1,2-dioxygenase system involved in aromatic hydrocarbon catabolism, and LadA-type monooxygenases involved in alkane degradation, were identified. Gas Chromatography-Mass Spectrometry (GC-MS) analysis of crude oil after biological treatment showed that Serratia sp. Tan611 strain was able to degrade n-alkanes (from C13 to C25). This bacterium was also shown to produce a biosurfactant, the emulsification index (E24) reaching 43.47 % and 65.22 %, against vegetable and crude oil, respectively. Finally, the formation of a biofilm was increased in the presence of crude oil. These observations make Serratia sp.Tan611 a good candidate for hydrocarbon bioremediation.
