“…Sequencing reads were quality checked (FastQC; Andrews, 2010) and trimmed (PRINSEQ-Lite; Schmieder and Edwards, 2011) before assembling the mate pairs using PANDA-SEQ (Masella et al, 2012). Annotations were made against the UNIPROTKB database (Leinonen et al, 2006), including protein sequences for bacteria, archaea, and fungi using BLASTX software (best hits with e value < 10 −4 ). All steps were performed using custom scripts.…”

Potential for phenol biodegradation in cloud waters

et al. 2018

Abstract. Phenol is toxic and can be found in many environments, in particular in the atmosphere due to its high volatility. It can be emitted directly from manufacturing processes or natural sources, and it can also result from benzene oxidation. Although phenol biodegradation by microorganisms has been studied in many environments, the cloud medium has not been investigated yet as the discovery of active microorganisms in cloud is rather recent. The main objective of this work was to evaluate the potential degradation of phenol by cloud microorganisms. Phenol concentrations were measured by GC-MS on two cloud samples collected at the PUY station (summit of Puy de Dôme, 1465 m a.s.l., France): they ranged from 0.15 to 0.21 µg L−1. The strategy for investigating its potential biodegradation involved a metatranscriptomic analysis and metabolic screening of bacterial strains from cloud water collected at the PUY station for phenol degradation capabilities (from the 145 tested strains, 33 were isolated for this work). Among prokaryotic messenger RNA-enriched metatranscriptomes obtained from three cloud water samples, which were different from those used for phenol quantification, we detected transcripts of genes coding for enzymes involved in phenol degradation (phenol monooxygenases and phenol hydroxylases) and its main degradation product, catechol (catechol 1,2-dioxygenases). These enzymes were likely from Gammaproteobacteria, a dominant class in clouds, more specifically the genera Acinetobacter and Pseudomonas. Bacterial isolates from cloud water samples (Pseudomonas spp., Rhodococcus spp., and strains from the Moraxellaceae family) were screened for their ability to degrade phenol: 93 % of the 145 strains tested were positive. These findings highlight the possibility of phenol degradation by microorganisms in clouds. Metatranscriptomic analysis suggested that phenol could be biodegraded in clouds, while 93 % of 145 bacterial strains isolated from clouds were able to degrade phenol.

“…Finally, ultrahigh-resolution mass spectrometry has been recently used to get a better identification of the dissolved organic compounds. Using GCxGC-HRMS technique, more than 100 semi-volatile compounds were detected and identified (Lebedev et al, 2018). Among them, phenols and phthalates that are strong pollutants were quantified.…”

Abstract. For the last twenty-five years, CO-PDD (Cézeaux-Aulnat-Opme-puy de Dôme) has evolved to become a full instrumented platform for atmospheric research. It is nationally accredited by CNRS, the French national center for scientific research, and recognized as a global station in the GAW network (Global Atmospheric Watch). It is a reference site of the European and national research infrastructures ACTRIS (Aerosol Cloud and Trace gases Research Infrastructure) and ICOS (Integrated Carbon Observing System). The site located on-top of the puy de Dôme mountain (1465 m a.s.l.) is completed by additional sites located at lower altitudes and adding the vertical dimension to the atmospheric observations: Opme (660 m a.s.l.), Cézeaux (410 m) and Aulnat (330 m). On the sites has been developed a unique combination of in-situ and remote sensing measurements capturing and documenting the variability of particulate and gaseous atmospheric composition, but also the optical, biochemical and physical properties of aerosol particles, clouds and precipitations. Given its location far away from any major emission sources, its altitude and the mountain orography, the puy de Dôme station is ideally situated to sample different air masses in the boundary layer or in the free troposphere depending on time of day and seasons. It is also an ideal place to study cloud properties with frequent presence of clouds at the top in autumn and winter. As a result of the natural conditions prevailing at the site and of the very exhaustive instrumental deployment, scientific studies at puy de Dôme strongly contribute to improving the knowledge in atmospheric sciences including the characterization of trends and variability, the understanding of complex and interconnected processes (microphysical, chemical, biological, chemical and dynamical) and providing a reference point for climate models. In this context, CO-PDD is a pilot site to conduct instrumental development inside its wind tunnel for testing liquid/ice cloud probes in natural conditions, or in-situ systems to collect aerosol and cloud. This paper reviews 25 years (1995–2020) of atmospheric observation at the station, and related scientific research contributing to atmospheric and climate science.

“…Phthalates, which are mainly used as plasticizers (for the manufac-ture of polyvinylchloride plastics) and solvents, are another class of widely occurring EDCs. Some phthalates (such as dimethyl phthalate, dibutyl phthalate, dioctyl phthalate and di(2-ethylhexyl)octyl phthalate) were on the priority pollutant list of the European Union, the United States and China [7,8].…”

This study investigated the occurrence of 42 pharmaceuticals and personal care products (PPCPs), 4 steroid estrogens and 15 phthalates in the effluents of 12 wastewater treatment plants (WWTPs) in 11 northern cities of China. Of the 61 emerging organic pollutants (EOPs), 49 EOPs were detected, and the detection frequencies of 18 compounds were over 90%. PPCPs were the predominant species and contributed to approximately half of the total EOP concentrations in the most of the investigated WWTPs. The four EOPs with the highest mean concentrations of the 49 were metoprolol (798.0 ng L −1), carbamazepine (597.5 ng L −1), sulpiride (543.5 ng L −1) and dimethyl phthalate (502.6 ng L −1). The levels of some detected EOPs showed positive correlations with the total nitrogen level. In the ecological risk evaluation, roxithromycin, diclofenac acid, sulfamethoxazole, ofloxacin, clindamycin, sulpiride, ibuprofen, 17α-ethynylestradiol, and dimethyl phthalate exhibited high or medium risks in the effluents. Four representative compounds, diclofenac acid, roxithromycin, sulfamethoxazole, and dimethyl phthalate, could be selected as indicators for predicting overall EOP levels.
