“…Previous studies indicated that Roseovarius was involved in the degradation of crude oil and PAH degradation in seawater [61,72,73]. The genus Paracoccus was previously found in activated sludge from a petrochemical plant and was proven to be capable of simultaneous nitrification and denitrification [54,74]. The study of Qian et al [75] confirmed the sulfatereduction coupling PAH degradation of Desulfovibrio and Petrimonas.…”

A massive volume of produced water (PW) generated in the process of oil extraction must be treated effectively due to its threat to the ecosystems and human health. Different biological treatment technologies have been used in wastewater treatment plant (WWTP) systems to treat PW. However, their influence on treatment performance has not been investigated. In this study, three PW treatment plants (PWTPs) with different treatment technologies were compared in the following aspects: microbial community structure and assembly, functional genes, and the spread of antibiotic resistance genes (ARGs). The results indicated that different biological treatment technologies led to the variations in the diversity and composition of the microbial community. Phylogenetic bin-based null model analysis (iCAMP) revealed that different treatment technologies deterministically drove the assembly of microbial communities, especially the genera associated with the removal of petroleum hydrocarbons. The results of the metagenomic analysis showed that the genes related to the degradation of alkanes and aromatic hydrocarbons were the most abundant in PWTP3, suggesting it had the highest petroleum degradation potential. In addition, the highest abundance of ARGs in PWTP1 indicated the potential facilitation of ARG dissemination in activated sludge systems. Network analysis indicated that the dissemination of ARGs in the PWTPs might be mediated by transposases.

“…It could be seen that the degradation of β-HCH was improved by only the mixture of A1 and J1 compared with that of the single bacteria, while the degradation of β-HCH by the other mixtures was generally reduced. Jing et al [32] screened three strains of ammoniaoxidizing bacteria from sludge and found that these three strains enhanced the conversion of ammonia nitrogen from 23.3 mg/L/d to 47.09 mg/L/d with a significant effect after compounding by experiments. Virgilio et al [33] found that certain mixtures of bacteria could significantly enhance the degradation of some pesticides.…”

Three degradation strains that can utilize β-Hexachlorocyclohexanes (β-HCH) as the sole carbon source were isolated from the soil substrate of constructed wetland under long-term β-HCH stress, and they were named A1, J1, and M1. Strains A1 and M1 were identified as Ochrobactrum sp. and strain J1 was identified as Microbacterium oxydans sp. by 16S rRNA gene sequence analysis. The optimum conditions for degradation with these three strains, A1, J1, and M1, were pH = 7, 30 °C, and 5% inoculum amount, and the degradation rates of 50 μg/L β-HCH under these conditions were 58.33%, 51.96%, and 50.28%, respectively. Degradation characteristics experiments showed that root exudates could increase the degradation effects of A1 and M1 on β-HCH by 6.95% and 5.82%, respectively. In addition, the degradation bacteria A1 and J1 mixed in a ratio of 1:1 had the highest degradation rate of β-HCH, which was 69.57%. An experiment on simulated soil remediation showed that the compound bacteria AJ had the best effect on promoting the degradation of β-HCH in soil within 98 d, and the degradation rate of β-HCH in soil without root exudates was 60.22%, whereas it reached 75.02% in the presence of root exudates. The addition of degradation bacteria or degradation bacteria-root exudates during soil remediation led to dramatic changes in the community structure of the soil microorganisms, as well as a significant increase in the proportion of aerobic and Gram-negative bacterial groups. This study can enrich the resources of β-HCH degrading strains and provided a theoretical basis for the on-site engineering treatment of β-HCH contamination.

“…In modern industry and life, pollution of water resources has become a serious environmental problem, and the discharge of wastewater has increased, in which the pollution caused by ammonia nitrogen in water bodies has attracted widespread attention. [1][2][3] Ammonia nitrogen wastewater comes from a wide range of sources, and is potentially hazardous to water ecosystems and human health. Conventional wastewater treatment methods may not be effective in removing ammonia nitrogen and have limitations, [4][5][6] so there is a need to find more efficient and environmentally friendly solutions.…”
