“…Phenol is a kind of typical xenobiotic compound, and the predicted function of "xenobiotics biodegradation and metabolism" is relevant to xenobiotic degradation (Tian et al 2020). In previous studies, with the increase in phenol concentration, the xenobiotic degradation function was improved (He et al 2021;Tian et al 2020;Wu et al 2019). In this study, xenobiotic degradation function declined over 30 days in river sediments as phenol was eliminated.…”

Phenol is widely used in industrial processes and has microbial toxicity. However, the effects of a phenol spill on the microbial community are not clear. The present study explored the changes of bacterial communities in river and fish pond sediments after a phenol spill. The bacterial richness and diversity in river sediments were lower on day 30 (36 days after the spill) than on day 0, while they increased in fish pond sediments. The structures and functions of bacterial communities in both river and fish pond sediments were changed, and a more dramatical variation was detected in fish pond sediments. In river sediments, Proteobacteria, Chloroflexi, Acidobacteria, Bacteroidetes, and Nitrospirae were the major bacterial phyla, and Chloroflexi was enriched. In fish pond sediments, genera Brevibacillus dominated bacterial communities initially, and bacterial composition showed a dramatic change on day 30. Most predicted metabolism functions, as well as genetic information processing functions of translation, replication, and repair, were enhanced in both river and fish pond sediments, while they showed an opposite change trend for xenobiotic degradation function. This work could strengthen our understanding of the effects of phenol spills on sediment bacterial communities in both lotic and lentic ecosystems.

“…Phenol can alter the microbial community structure in manmade ecosystems (Gomez-Acata et al 2017;Pereira et al 2014;Poirier et al 2016;Wu et al 2019). But the shift in bacterial community structure in natural ecosystems induced by phenol is still unknown.…”

“…For further exploring the BaP biodegradation pathway, Wu, Wang et al (2019) investigated that Geobacter , Diaphorobacter and Tissierella_Soehngenia were the dominant bacterial community in anaerobic activated sludge whereas Thauera , Dyella and Rhodanobacter were majored in aerobic activated sludge associated with biodegradation of BaP with phenol as co‐substrate in case of CWW treatment. Further result showed that the phenol as co‐substrate in the process of BaP degradation induced bacterial diversity, the dominant one of which may have the ability to degrade BaP even polycyclic aromatic hydrocarbons.…”

This paper provides an overview of activated sludge related to suspended growth processes for the year 2019. The review encompasses process modeling of activated sludge, microbiology of activated sludge, process kinetics and mechanism, nitrogen and phosphorus control, design, and operation in the activated sludge field. The fate and effect of xenobiotics in activated sludge, including trace organic contaminant and heavy metal xenobiotics, which had influence on the growth of suspended sludge, are covered in this review. Compared to past reviews, many topics show increase in activity in 2019. These include, biokinetics process of aerobic granular sludge formation, pyrolysis kinetic mechanism of granular sludge. These topics are referred to formation and disintegration of granular sludge. Other sections include activated sludge settling model, toxicity resistant microbial community, nitritation-anammox processes for nitrogen removal, and respirometry used in the operation of real wastewater treatment plant are especially highlighted in this review.

The contents of ammonium, phenolic compounds, sulfides (S 2− ), total phosphorus (TP), and total nitrogen (TN) were analyzed by the colorimetric methods with a spectrophotometer (Genesys TM-5, Spectronic Inc., USA) [9]. The concentration of CN − was measured by the pyridine-pyrazolone method after distillation [9].…”

The pre-aerobic process of coking wastewater treatment has strong capacity of decarbonization and detoxification, which contribute to the subsequent dinitrogen of non-carbon source/heterotrophic denitrification. The COD removal rate can reach > 90% in the first aerobic bioreactor of the novel O/H/O coking wastewater treatment system during long-term operation. The physico-chemical characteristics of influent and effluent coking wastewater in the first aerobic bioreactor were analyzed to examine how they correlated with bacterial communities. The diversity of the activated sludge microbial community was investigated using a culture-independent molecular approach. The microbial community functional profiling and detailed pathways were predicted from the 16S rRNA gene-sequencing data by the PICRUSt software and the KEGG database. High-throughput MiSeq sequencing results revealed a distinct microbial composition in the activated sludge of the first aerobic bioreactor of the O/H/O system. Proteobacteria, Bacteroidetes, and Chlorobi were the decarbonization and detoxification dominant phyla with the relative abundance of 84.07 ± 5.45, 10.89 ± 6.31, and 2.96 ± 1.12%, respectively. Thiobacillus, Rhodoplanes, Lysobacter, and Leucobacter were the potential major genera involved in the crucial functional pathways related to the degradation of phenols, cyanide, benzoate, and naphthalene. These results indicated that the comprehensive understanding of the structure and function diversity of the microbial community in the bioreactor will be conducive to the optimal coking wastewater treatment.
