Finally, the mangroves were dominated by representatives of Deltaproteobacteria, mainly Desulfobacteraceae and Synthrophobacteraceae, and were associated with high salinity and soil pore-water concentrations of ammonium (N-NH4+). These communities suggest methane consumption in freshwater wetlands, and sulfate reduction in deep soils of marshes and in mangroves. Our work contributes to the important goal of describing reference conditions for specific wetlands in terms of both bacterial communities and their drivers. This information may be used to monitor change and assess wetland health and function.The occurrence and removal of ten bisphenol analogues (BPs) in municipal wastewater treatment plants (WWTPs) and laboratory scale activated sludge bioreactor (ASBR) were studied. BIBR 1532 in vivo All targeted BPs except for tetrachlorobisphenol A (TCBPA) were detected in the four WWTPs (W1, W2, W3 and W4) in the ng/L and ng/g dry weight range in wastewater and activated sludge, respectively, indicating that in addition to BPA, the BPA substitutes were widely used in our daily life and industrial production. Discrepant results regarding the removal efficiencies of BPs by different wastewater treatment processes were obtained. The removal rates were 55.6%, 24.4%, -10.1%, 71.4%, 38.9%, 58.0%, 39.1% and 6.4% in W1, 65.4%, 32.8%, 44.7, -13.5%, 20.1%, -29.6%, -25.1% and 99.4% in W2, 11.6%, 48.8%, 38.9%, 22.0%, 99.0%, -29.2%, -56.5% and 32.6% in W3, 33.9%, 30.5%, 17.4%, -47.6%, 62.9%, 83.0%, 4.4% and -4.3% in W4, for BPA, BPB, BPE, BPF, BPS, BPZ, BPAF and BPAP, respectively. The removal of ten targeted BPs in lab-scale continuous flow conventional ASBR and the key factors were investigated. The simulated laboratory-scale ASBR were highly effective in removing BPA, BPB, BPE, BPF, BPM and BPS with removal efficiencies of >94.3%, while BPZ, BPAP, BPAF and TCBPA were recalcitrant to elimination in the stimulated bioreactor with removal efficiencies of 71.3 ± 13.7%, 55.1 ± 21.2%, 47.4 ± 9.5% and 45.3 ± 16.6%, respectively. Protonation, hydrophobicity and molecular features of BPs were critical for their elimination in wastewater.The degradation by bacteria has been considered the main process for eliminating nonhalogenated organophosphate esters (OPEs) from wastewater treatment plants (WWTPs), but limited research has reported the biodegradation processes and clarified the microbial-mediated mechanisms for nonhalogenated OPE degradation in WWTPs. The aim of this study was to monitor the biodegradation of the most common nonhalogenated OPEs, namely, tris(2-butoxyethyl) phosphate (TBOEP), tris (n-butyl) phosphate (TNBP) and trisphenyl phosphate (TPHP), under aerobic conditions by sludge cultures from a conventional sewage plant. The microbial cultures were enriched separately with each OPE from activated sludge cultures, and the presence of glucose significantly enhanced degradation of the OPEs during the enrichment. The removal ratios for the three OPEs reached 29.3-89.9% after 5 cycles (25 days) of cultivation, and the first-order degradation kinetics followed the order of TPHP > TBOEP > TNBP, with their half-lives ranging between 12.8 and 99.0 h. Pathways of hydrolysis, hydroxylation, methoxylation, and substitution were confirmed for the aerobic biodegradation of these nonhalogenated OPEs, but only di-alkyl phosphates (DAPs) largely accumulated in culture medium as the most predominant transformation products. Phylotypes in Klebsiella were significantly more abundant during OPE biodegradation than in the initial sludge, which indicated that these microorganisms are associated with the biodegradation of nonhalogenated OPEs in sludge culture. Biodegradation of all investigated nonhalogenated OPEs was associated with a significant reduction in the residual toxicity to Vibrio fischeri, indicating a rather positive ecotoxicological outcome of the aerobic biotransformation processes achieved by the enriched sludge culture.Pond-ditch circulation systems (PDCSs) were proved to be an appropriate operation selection in rural wastewater remediation. However, the biological dephosphorization process has not been investigated and quantified in PDCSs. In this study, PDCSs exhibited higher total phosphorus (TP) removal efficiencies (77.8%-97.4%). The activities of polyphosphate kinase (PPK) and exopolyphosphatase (PPX) tightly associated with phosphorus biological removal ranged from 0.356 to 11.844 μmol hydroxamic acid min-1 mg-1 protein, and 0.008 to 0.446 μmol p-nitrophenol min-1 mg-1 protein, respectively. Both PPK and PPX in PDCSs increased with time, peaked at day 30, and then declined, and were negatively correlated with sediment total phosphorus (STP), sediment inorganic phosphorus (SIP), P bound to Al/Fe/Mn oxides and hydroxides (NaOH-P), P associated with Ca (HCl-P), and organic matter (OM) (p less then 0.05). Results of high-throughput sequencing suggested that Bacillus (0.46%-19.77%) and Clostridium (0.40%-21.0%) genus miestimated indirect pathway influencing on biological dephosphorization process in PDCSs.Two factors complicate the ecological status classification of very large rivers in Europe according to the EU Water Framework Directive First, current assessment methods do not fully consider the specific ecology of very large rivers (such as lateral connectivity and the role of floodplains for ecological status). link2 Second, most of Europe's very large rivers have been severely altered by human activities such as flood protection, damming and navigation. The aim of our study is to develop an assessment method for very large rivers by identifying suitable biological metrics as the basis for multi-metric bioassessment using benthic invertebrates. Based on the pan-European typology of very large rivers by Borgwardt et al. (2019), we established a river type-specific assessment approach using invertebrate samples from 25 European countries and 94 very large rivers. The frequency and intensity of eight pressures jointly acting on the sampling sites were described, and a selection of suitable invertebrate community metrics were correlated with the pressure intensities to establish pressure-response relationships. The very large river types differ in terms of relevant pressures and pressure combinations, with the invertebrate communities distinctly responding to these pressure patterns. Neozoa dominance correlated strongly with 'navigation', being a major pressure at very large rivers, which entails severe hydro-morphological alterations such as channelization, riparian vegetation alteration and impoundment. link3 Under combined pressures, a critical community turnover became evident in terms of neozoa outnumbering EPT taxa and the ratio of hemilimnic invertebrates decreasing. We propose ten bioassessment metrics, including measures of biological diversity as well as newly generated indicators, for the development of a European type-specific assessment method for very large rivers.The Great Amazon Reef System (GARS) covers an estimated area of 56,000 km2 off the mouth of the Amazon River. Living rhodolith holobionts are major benthic components of the GARS. However, it is unclear whether environmental conditions modulate the rhodolith microbiomes. Previous studies suggest that environmental parameters such as light, temperature, depth, and nutrients are drivers of rhodolith health. However, it is unclear whether rhodoliths from different sectors (northern, central, and southern) from the GARS have different microbiomes. We analysed metagenomes of rhodoliths (n = 10) and seawater (n = 6), obtained from the three sectors, by illumina shotgun sequencing (total read counts 25.73 million). Suspended particulate material and isotopic composition of dissolved organic carbon (δ13C) indicated a strong influence of the Amazon river plume over the entire study area. However, photosynthetically active radiation at the bottom (PARb) was higher in the southern sector reefs, ranging from 10.1 to 14.3ds. The results confirm the conserved nature of rhodolith microbiomes even under pronounced environmental gradients. Subtle taxonomic and functional differences observed in rhodolith microbiomes may enable rhodoliths to thrive in changing environmental conditions.With the widespread application of rare earth elements (REEs) in environment safety, food and medicine, they accumulate in the ecosystem and different human organs where REEs exert certain biological effects. Low dose REEs are proved to perform antioxidant effects, while high concentration can cause oxidative stress. However, scant information about rational doses and underlying mechanism of REEs as oxidants/antioxidants were illustrated. To elucidate these problems, here we performed a study that the ICR mice were received 0.1, 0.2, 1.0, 2.0 and 20.0 mg/kg lanthanum nitrate (La(NO3)3) by gavage for 30 days, and then were given 12 mL/kg ethanol once to undergo acute ethanol-induced oxidative stress. The antioxidant enzymes, antioxidants, peroxides and related proteins in Keap 1/Nrf2/p62 signaling pathway were measured. The results showed that La(NO3)3 inhibited hepatic morphological alternations by histopathological examination. Meanwhile, elevated superoxide dismutase (SOD) and glutathione (GSH), coupled with decreased alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA) and protein carbonyl (PC) were observed in serum and liver tissues of mice by enzyme-linked immunosorbent assay test. Furthermore, western blot analysis demonstrated that oxidative stress was alleviated due to enhanced NF-E2-related factor 2 (Nrf2) and phosphorylated p62 expressions as well as lower Kelch-like ECH-associated protein-1 (Keap 1), followed by the activation of heme oxygenase 1 (HO-1), NAD(P)H quinone oxidoreductase 1 (NQO-1) and glutamate cysteine ligase, catalytic (GCLC) proteins. Our findings clearly highlighted that La(NO3)3 could restore the redox homeostasis disrupted by ethanol through provoking Keap 1/Nrf2/p62 signaling pathway, and the optimal dosages were 1.0 and 2.0 mg/kg.The persistence of antibiotic resistance genes (ARGs) under the aerobic vs. anaerobic conditions is unknown, especially under different fertilization. Towards this goal, a microcosm experiment was carried out with chemical fertilized and manured soil under aerobic and anaerobic conditions. High throughput qPCR was used to analyze ARGs with 144 primer sets and sequencing for microorganisms. Completely different dynamics of ARGs were observed in soil under aerobic and anaerobic conditions, regardless of the fertilization type. ARGs had different half-lives, even though they confer resistance to the same type of antibiotics. Aminoglycoside, chloramphenicol, macrolide - lincosamide - streptogramin B (MLSB) and tetracycline resistance genes were significantly accumulated in the aerobic soils. Anaerobic soil possessed a higher harboring capacity for exogenous microorganisms and ARGs than aerobic soil. The interaction between ARGs and mobile genetic elements (MGEs) in manured soil under aerobic condition was more pronounced than the anaerobic condition. These findings unveil that anaerobic soil could play a more positive role in reducing potential risk of ARGs in the farmland environment.
