On January 31, 2020, Liang, Bin; Yun, Hui; Kong, Deyong; Ding, Yangcheng; Li, Xiangkai; Vangnai, Alisa S.; Wang, Aijie published an article.Quality Control of 1,3-Diphenylurea The title of the article was Bioaugmentation of triclocarban and its dechlorinated congeners contaminated soil with functional degraders and the bacterial community response. And the article contained the following:

Partial removal of haloarom. antimicrobial triclocarban (TCC) during wastewater treatment caused the final introduction of residual TCC into soils. Bioaugmentation has been proposed for the biodegradation of TCC and its dechlorinated congeners 4,4′-dichlorocarbanilide (DCC) and carbanilide (NCC) in soil. The isolated TCC-degrading strain Ochrobactrum sp. TCC-2 and chloroanilines-degrading strain Diaphorobacter sp. LD72 were used to study the removal efficiency of TCC, DCC and NCC mixture and their chloroanilines intermediates, resp. The potential degradation competition between TCC and its dechlorinated congeners, and the response of bacterial community during the bioremediation were also investigated. The biodegradation of DCC and TCC was significantly enhanced for soil with inoculums compared with sterilized and natural soils. Chloroanilines products could also be effectively removed. For the degradation of combined substrates in the aqueous medium, NCC had neg. effect on the degradation of TCC and DCC, while TCC and DCC neg. influenced each other. The bioaugmentation with two degraders obviously changed the phylogenetic composition and function of indigenous soil microbiome. Importantly, the inoculated degraders could be maintained, suggesting their adaptability and potential application in bioaugmentation for such recalcitrant contaminants. This study offers new insights into the enhanced bioremediation of TCC and its dechlorinated congeners contaminated soils by the bioaugmentation of functional degraders and the structure and function response of the indigenous soil microbiome to the bioremediation process. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Quality Control of 1,3-Diphenylurea

On August 15, 2021, Zhang, Lili; Zhang, Cheng; Lian, Keting; Liu, Chongxuan published an article.SDS of cas: 144-80-9 The title of the article was Effects of chronic exposure of antibiotics on microbial community structure and functions in hyporheic zone sediments. And the article contained the following:

Microbial communities in hyporheic zones (HZ) provide vital biogeochem. functions such as contaminant degradation for river ecosystems. Antibiotics are contaminants that have been increasingly detected in HZ sediments. In this study, sediments from different HZ locations in a contaminated river, Maozhou river, China were sampled and analyzed using qPCR and high-throughput sequencing to investigate the effect of antibiotic contamination on microbial community structures and functions in HZ sediments. Results indicated that types and concentrations of antibiotics in HZ sediments were heterogeneously distributed that were largely consistent with the distribution of antibiotic sources. Sediments near animal farm and hospital contained higher antibiotic concentrations compared with those from mainstream. The distribution of ARGs was well correlated with antibiotics. Bacterial indicator genera indicating differences between mainstream area and other sampling areas were pos. correlated with antibiotics, suggesting the influences of antibiotics on reshaping microbial community structures. PICRUSt revealed pos. relationships between antibiotics and predicted functional genes involved in defense, signal transduction, and recombination and repair. This imply the defensive response of microbial communities on antibiotic attack. These results indicated that antibiotic contamination in the watershed posed a potential risk on HZ microbial community structures and functions, which may further threaten river ecosystem functions. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).SDS of cas: 144-80-9

On February 1, 2016, Hopp, Jens; Trieloff, Mario; Ott, Ulrich published an article.Computed Properties of 97-09-6 The title of the article was I-Xe ages of enstatite chondrites. And the article contained the following:

In order to elucidate the early thermal history of enstatite chondrite parent bodies we determined 129I-129Xe whole rock ages of enstatite chondrites (5 EH, 2 EL, one EH impact melt) relative to the Shallowater reference meteorite (4562.3 ± 0.4 Ma, all errors are 1σ). I-Xe ages of both EL6 chondrites (LON 94100: -4.38 ± 0.60 Ma and Neuschwanstein: -3.87 ± 0.73 Ma – neg. sign indicates ages younger than Shallowater) agree well with data of other EL6 chondrites. LON 94100 displayed a second isochron at lower temperatures equivalent to a younger age of -5.25 ± 1.17 Ma, perhaps reflecting different retention temperatures of resp. carrier phases during sequential cooling. The enstatite chondrites Abee (EH4), Indarch (EH4), EET 96135 (EH4/5) and St. Marks (EH5) encompass a I-Xe age range of +0.57 ± 1.05 Ma (EET 96135 #1) to -0.45 ± 0.72 Ma (Abee), again in agreement with previously reported ages of EH chondrites. Only the age of St. Marks differs strongly from previously reported younger ages, now being more in accordance with other members of the EH clan. The EH3 chondrite Sahara 97096 showed the youngest I-Xe age of -7.87 ± 0.46 Ma distinctly younger than other I-Xe ages of EH chondrites, including other EH3s. Due to the apparent high retention temperature of the I-Xe system in enstatite (estimated >800 °C) this young age implies a later resetting of the I-Xe system by a severe thermal, likely impact-induced, event. The EH impact melt LAP 02225 records a similarly young thermal event. Though no isochron relationship could be established, the data fall within an apparent I-Xe age range of +5 to +15 Ma, similar to Sahara 97096. Overall, EH chondrite parent body experienced a thermal history determined by a complex interplay between impact disturbances and parent body metamorphism. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Computed Properties of 97-09-6
