Highly enhanced biodegradation of pharmaceutical and personal care products in a novel tidal flow constructed wetland with baffle and plants was written by Cheng, Yu-Xiao;Chen, Jun;Wu, Dan;Liu, You-Sheng;Yang, Yong-Qiang;He, Lu-Xi;Ye, Pu;Zhao, Jian-Liang;Liu, Shuang-Shuang;Yang, Bin;Ying, Guang-Guo. And the article was included in Water Research in 2021.Reference of 101-20-2 This article mentions the following:

Research on decentralized wastewaters deserves special focus due to the potential abundance of emerging organic pollutants including pharmaceutical and personal care products (PPCPs), which might pose serious threats to the local water bodies and even to human health. Constructed wetland (CW) is a common decentralized wastewater treatment technol., with a certain ability to eliminate PPCPs. Nonetheless, PPCPs removal in common CWs is frequently challenging, besides, the removal mechanism remains elusive. Based on our previous study, tidal flow constructed wetlands (TFCWs) is effective in nitrogen removal. Here, 3 TFCWs with different modifications (baffle, plants, both baffle and plants) were constructed to treat raw domestic sewage and specifically to evaluate the removal efficiencies and mechanism of PPCPs. 24 PPCPs including 7 antibiotics, 8 steroid hormones and 9 biocides were detected in the level of 1.10 ± 0.29 ng/L-799 ± 10.6 ng/L in the influents. Consequently, we found that modification with both baffle and plants significantly influenced the removal of PPCPs. Moreover, the highest removal rates of biocides (97.1 ± 0.29%), steroid hormones (99.8 ± 0.02%), and antibiotics (90.2 ± 1.60%) were achieved via both baffles and plants in TFCWs. Based on the mass balance anal., microbial degradation dominated the removal of PPCPs with a percentage higher than 85.7%, followed by substrate adsorption (5.22 x 10^-2-14.3%) and plant uptake (1.66 x 10^-3-0.44%). Further, 16S rDNA sequencing anal. revealed that the presence of baffle and plants improve the removal efficiency of PPCPs by means of enhancing microbial diversity and changing dominant microorganisms. Moreover, Thaumarchaeota was potentially the key microorganism in the phylum level for PPCPs elimination by TFCWs through LEfSe (linear discriminant anal. (LDA) effect size) anal. These findings provide new insights into the removal of PPCPs in CWs. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Reference of 101-20-2).

In recent times, there has been an inspired research on combining semiconducting metal oxides for improved industrial applications. Significantly, wastewater removal is concerned and the researchers are finding new methodologies for removing azo dyes that possess a high level of carcinogenic effects. In this connection, this work investigates the photocatalytic activity of synthesized TiO₂/ZnO nanocomposite irradiated under UV and visible light. The application of the work involves the removal of methylene blue (MB) dye solution Initial work begins with the novel synthesis of TiO₂/ZnO coupled system by integrated sol-gel and thermal decomposition methods. Then, various characterization techniques brought out the existing properties of the prepared TiO₂/ZnO catalyst. The X-ray diffraction measurements showed the assorted tetragonal and hexagonal structures. The spherical shape mixed with hexagonal shaped particles were perceived via transmission electron microscopy (TEM). Besides, from photoluminescence spectrum (PL) results, the TiO₂/ZnO coupled system displayed slowing down of charge recombination, because of the intermediate states that helps in intensifying the photocatalytic activity. The dual absorption bands corresponding to UV region were deep-rooted from UV-vis spectroscopy. Further, the valuable application of the catalyst in removing methylene blue (MB) dye under both UV and visible light was carried out. The catalyst had displayed 90% of degradation within 40 min under UV light conditions. The other hand, visible light illumination of the catalyst provides divergent results as it possess lesser light absorption. Therefore, this catalyst was unable to yield visible light photocatalytic activity. Hence, this captivating research would bring the wastewater treatment progression using UV light.

Plasmids disseminate pollutant-catabolic genes through horizontal transfer and contribute to the catabolic potential of the host microbial community. Genetic bioaugmentation of conjugative catabolic plasmids has recently been considered an effective and novel approach for long-term bioremediation of contaminated sites. In this study, we engineered an IncP-1β-2 subgroup plasmid pDCA-1 from Achromobacter sp. ANB-1 for its potential application in genetic bioaugmentation. A dcaA1A2B cluster responsible for the deamination of chloroaniline to chlorocatechol and a 1,2-dioxygenase gene (ccdC) for the ring cleavage of chlorocatechol were found to locate on the broad host range plasmid pDCA-1. Insertion of an amidase gene (phh or tccA2) at the accessory region of plasmid pDCA-1 greatly expanded its catabolic substrate spectrum from chloroaniline (3-chloroaniline and 3,4-dichloroaniline) to herbicides (linuron, propanil, propham, and chlorpropham), bacteriostatic agent (triclocarban), plant regulator (forchlorfenuron), and insecticide (diflubenzuron). Taking advantages of high-throughput cell sorting and 16S rRNA gene-based amplicon sequencing, we depicted the diversity of bacterial recipients for the engineered plasmid pDCA-1-gfp-phh in a soil bacterial consortium, showing an excellent conjugative transfer capacity of the pDCA-1 derivative to various Gram neg. and even pos. strains in natural environment. All in all, the engineered plasmid pDCA-1 had a great potential in genetic bioaugmentation of the sites contaminated with chloroanilines and their derivatives In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).

And the article was included in Journal of Heterocyclic Chemistry in 2021.Recommanded Product: (Chloromethanetriyl)tribenzene This article mentions the following:

New alkylimidazoles functionalized with a homoserine lactone or an alkyloxycarbonyl moiety was synthesized as N-acylhomoserine lactones (AHLs) analogs. The 1,4-disubstituted imidazole derivatives were prepared by alkylation of 4(5)-alkylimidazoles with α-bromo-γ-butyrolactone or Et α-bromoacetate. An alternative route was preferred for the synthesis of their 1,5-disubstituted counterparts based on the use of a N₁-protected alkylimidazole, its alkylation to an N₃-imidazolyl-α-acetate and deprotection to the desired 1,5-disubstituted esters and subsequent alkylation of the acetate moiety with cyclic ethylene sulfate followed by acid-catalyzed cyclization. The ability to modulate bacterial quorum sensing of all new compounds was compared to that of previously reported AHL analogs in which the amide bond is replaced by a heterocyclic group.
