Mercury bioremediation in aquatic environment by genetically modified bacteria with self-controlled biosecurity circuit was written by Xue, Yubin;Du, Pei;Ibrahim Shendi, Amal Amin;Yu, Bo. And the article was included in Journal of Cleaner Production in 2022.Synthetic Route of C9H18O5S The following contents are mentioned in the article:

Heavy metal pollution such as mercury (Hg²⁺) poses a severe threat to food security worldwide because of enrichment through food chain and, eventually, to the human body. Biol. remediation approaches are promising, but in some cases, the natural microorganisms are not ideal for practical application, which requires genetic modification of such organisms. However, the threat of genetically modified bacteria being released into the environments has long been the major concern that limits the applications of such technologies. In this study, we designed and optimized a genetic circuit that is capable of activating a Hg²⁺ adsorption module after sensing Hg²⁺ in waterbody, and killing cells with a cell suicide module in a programmable manner. With this circuit, the engineered Escherichia coli cells are programmed to express Hg²⁺ adsorption protein only when Hg²⁺ concentration is above a certain threshold. Then, cells absorbed with Hg²⁺ can be removed from natural environments with magnetically immobilized strategy and the remaining cells are programmed to be killed by the suicide module when Hg²⁺ concentration drops below a threshold in waterbody. Importantly, the suicide module was carefully optimized to ensure the escape rate is below 10^-9, which meets the recommendation demanded by U. S. NIH guideline. The absorption cells could be reused for 5 cycles, with an Hg²⁺ adsorption efficiency steadily above 95% and escape rates below 10^-9. Thus, the advancement of this study sheds light on using engineered microbes directly in an open circumstance. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Synthetic Route of C9H18O5S).

(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Synthetic Route of C9H18O5S

Liquefied wheat straw as phenols for bio-based phenolic resins: Reaction parameters optimization and chemical routes was written by Jiang, Xiuming;Li, Peilong;Ding, Zhan;Li, Huifeng;Bing, Hui;Zhang, Linqing. And the article was included in Industrial Crops and Products in 2022.Quality Control of 4,4′-Methylenediphenol The following contents are mentioned in the article:

The value-added conversion of biomass materials is accepted as a promising approach to alleviate the energy crisis and promote green chem. This work aims to investigate the conversion process and chem. routes from liquefied wheat straw (LWS) to bio-based phenolic resins (BPFRs) and their potential opportunity as an alternative to petroleum-based asphalt binders. Response surface methodol. (RSM) was introduced for the optimization of synthesis conditions, while the Fourier transform IR (FTIR), NMR (NMR) and SEM were used to explore the chem. reactions during the conversion process and the morphol. characteristics of resins. The feasibility of BPFRs application in asphalt binders was investigated based on rheol. tests. The results demonstrate that the LWS is rich in phenolic compounds with reactive sites in para or ortho positions, which can replace petroleum-based phenol in the reaction with formaldehyde. Further, the produced intermediates, methylolphenols and bisphenol F, are subject to the condensation reaction to form BPFR mols. with about five phenolic nuclei. The connection between phenolic nuclei is dominated by para-methylene bridges (about 70%). The synthesis is suggested to be carried out at a molar ratio of phenol-to-formaldehyde of 0.75 without addnl. sulfuric acid, and the preferred polymerization temperature and time are 95°C and 120 min. It should be noted that the reactivity of LWS is lower than that of petroleum-based phenol and may be accompanied by self-curing effects. Noticeable folds are observed on the surface of BPFRs. Encouragingly, acceptable compatibility and rutting resistance in the BPFR-asphalt system are identified. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Quality Control of 4,4′-Methylenediphenol).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Quality Control of 4,4′-Methylenediphenol

Identification of bisphenols and derivatives in greenhouse dust as a potential source for human occupational exposure was written by Caballero-Casero, Noelia;Rubio, Soledad. And the article was included in Analytical and Bioanalytical Chemistry in 2022.Application of 620-92-8 The following contents are mentioned in the article:

Abstract: Bisphenol A (BPA) and alternative bisphenols are widely used in the industrial production of polycarbonates and resin polymers. Adverse effects on human health have been described for BPA and owing to the structural similarity of alternative bisphenols and derivatives, a similar toxicity profile is expectable. Dust can act as a sink for bisphenols owing to the large surface area to mass ratio. Human risk exposure to bisphenols via indoor dust has been widely assessed in the last decade. The environmental conditions inside greenhouses, among other factors, facilitate that chems. are released from greenhouse building materials to dust. This study aims to explore for the first time the potential of greenhouse dust as a new source of bisphenols for human exposure. For this purpose, a supramol. solvent-based method was applied to the extraction of twenty-one bisphenols from greenhouse dust, prior to their determination by liquid chromatog.-tandem mass spectrometry. Nineteen bisphenols were found in the five greenhouse dust samples analyzed, with concentrations ranging from 5275 ng g-1 (BPA) to 0.25 ng g-1 (trichlorobisphenol A). The average daily dose (ADD) via dust ingestion for bisphenol compounds was calculated, in order to estimate the occupational exposure for inadvertent dust ingestion. Despite the calculated ADD value for BPA (47.81 ng kg-1 day-1) being below the tolerable daily intake proposed by EFSA (4·103 ng kg-1 day-1), this value was considerably higher than those previously reported for indoor dust, which brings to light the importance of considering greenhouse dust as bisphenols source of exposure for greenhouse workers. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8Application of 620-92-8).

4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Application of 620-92-8

Signal amplification and optimization of riboswitch-based hybrid inputs by modular and titratable toehold switches was written by Hwang, Yunhee;Kim, Seong Gyeong;Jang, Sungho;Kim, Jongmin;Jung, Gyoo Yeol. And the article was included in Journal of Biological Engineering in 2021.Electric Literature of C9H18O5S The following contents are mentioned in the article:

Synthetic biol. circuits are widely utilized to control microbial cell functions. Natural and synthetic riboswitches are attractive sensor modules for use in synthetic biol. applications. However, tuning the fold-change of riboswitch circuits is challenging because a deep understanding of the riboswitch mechanism and screening of mutant libraries is generally required. Therefore, novel mol. parts and strategies for straightforward tuning of the fold-change of riboswitch circuits are needed. In this study, we devised a toehold switch-based modulator approach that combines a hybrid input construct consisting of a riboswitch and transcriptional repressor and de-novo-designed riboregulators named toehold switches. First, the introduction of a pair of toehold switches and triggers as a downstream signal-processing module to the hybrid input for coenzyme B12 resulted in a functional riboswitch circuit. Next, several optimization strategies that focused on balancing the expression levels of the RNA components greatly improved the fold-change from 260- to 887-fold depending on the promoter and host strain. Further characterizations confirmed low leakiness and high orthogonality of five toehold switch pairs, indicating the broad applicability of this strategy to riboswitch tuning. The toehold switch-based modulator substantially improved the fold-change compared to the previous sensors with only the hybrid input construct. The programmable RNA-RNA interactions amenable to in silico design and optimization can facilitate further development of RNA-based genetic modulators for flexible tuning of riboswitch circuitry and synthetic biosensors. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Electric Literature of C9H18O5S).

(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Electric Literature of C9H18O5S

PqsE expands and differentially modulates the RhlR quorum sensing regulon in Pseudomonas aeruginosa was written by Letizia, Morgana;Mellini, Marta;Fortuna, Alessandra;Visca, Paolo;Imperi, Francesco;Leoni, Livia;Rampioni, Giordano. And the article was included in Microbiology Spectrum in 2022.Electric Literature of C9H18O5S The following contents are mentioned in the article:

In the opportunistic pathogen Pseudomonas aeruginosa, many virulence traits are finely regulated by quorum sensing (QS), an intercellular communication system that allows the cells of a population to coordinate gene expression in response to cell d. The key aspects underlying the functionality of the complex regulatory network governing QS in P. aeruginosa are still poorly understood, including the interplay between the effector protein PqsE and the transcriptional regulator RhlR in controlling the QS regulon. Different studies have focused on the characterization of PqsE- and RhlR-controlled genes in genetic backgrounds in which RhlR activity can be modulated by PqsE and pqsE expression is controlled by RhlR, thus hampering identification of the distinct regulons controlled by PqsE and RhlR. In this study, a P. aeruginosa PAO1 mutant strain with deletion of multiple QS elements and inducible expression of pqsE and/or rhlR was generated and validated. Transcriptomic analyses performed on this genetic background allowed us to unambiguously define the regulons controlled by PqsE and RhlR when produced alone or in combination. Transcriptomic data were validated via reverse transcription-quant. PCR (RT-qPCR) and transcriptional fusions. Overall, our results showed that PqsE has a negligible effect on the P. aeruginosa transcriptome in the absence of RhlR, and that multiple RhlR subregulons exist with distinct dependency on PqsE. Overall, this study contributes to untangling the regulatory link between the pqs and rhl QS systems mediated by PqsE and RhlR and clarifying the impact of these QS elements on the P. aeruginosa transcriptome. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Electric Literature of C9H18O5S).

Dynamic and single cell characterization of a CRISPR-interference toolset in Pseudomonas putida KT2440 for beta-ketoadipate production from p-coumarate was written by Fenster, Jacob A.;Werner, Allison Z.;Tay, Jian Wei;Gillen, Matthew;Schirokauer, Leo;Hill, Nicholas C.;Watson, Audrey;Ramirez, Kelsey J.;Johnson, Christopher W.;Beckham, Gregg T.;Cameron, Jeffrey C.;Eckert, Carrie A.. And the article was included in Metabolic Engineering Communications in 2022.Synthetic Route of C9H18O5S The following contents are mentioned in the article:

Pseudomonas putida KT2440 is a well-studied bacterium for the conversion of lignin-derived aromatic compounds to bioproducts. The development of advanced genetic tools in P. putida has reduced the turnaround time for hypothesis testing and enabled the construction of strains capable of producing various products of interest. Here, we evaluate an inducible CRISPR-interference (CRISPRi) toolset on fluorescent, essential, and metabolic targets. Nuclease-deficient Cas9 (dCas9) expressed with the arabinose (8K)-inducible promoter was shown to be tightly regulated across various media conditions and when targeting essential genes. In addition to bulk growth data, single cell time lapse microscopy was conducted, which revealed intrinsic heterogeneity in knockdown rate within an isoclonal population. The dynamics of knockdown were studied across genomic targets in exponentially-growing cells, revealing a universal 1.75 ± 0.38 h quiescent phase after induction where 1.5 ± 0.35 doublings occur before a phenotypic response is observed To demonstrate application of this CRISPRi toolset, β-ketoadipate, a monomer for performance-advantaged nylon, was produced at a 4.39 ± 0.5 g/L and yield of 0.76 ± 0.10 mol/mol from p-coumarate, a hydroxycinnamic acid that can be derived from grasses. These cultivation metrics were achieved by using the higher strength IPTG (1K)-inducible promoter to knockdown the pcaIJ operon in the βKA pathway during early exponential phase. This allowed the majority of the carbon to be shunted into the desired product while eliminating the need for a supplemental carbon and energy source to support growth and maintenance. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Synthetic Route of C9H18O5S).

A comparison between MBP- and NT* as N-terminal fusion partner for recombinant protein production in E. coli was written by Raran-Kurussi, Sreejith;Sharwanlal, Sarawata B.;Balasubramanian, Deepa;Mote, Kaustubh R.. And the article was included in Protein Expression and Purification in 2022.Related Products of 367-93-1 The following contents are mentioned in the article:

Advances in structural biol. have been fueled in part by developing techniques for large-scale heterologous expression and purification of proteins. Nevertheless, this step is still a bottleneck in biophys. studies of many proteins. Often, fusion proteins are used to increase expression levels, solubility, or both. Here, we compare a recently reported fusion tag, NT*, with Maltose Binding Protein (MBP), a well-known fusion tag and solubility enhancer. The NT* shows high expression and solubility when used as an N-terminal fusion partner for several aggregation-prone peptides. Its efficacy in enhancing the solubility of aggregation-prone globular proteins has, however, not been tested. We find here that although the overall expression levels for NT* fusions are much higher than those for the MBP fusion, MBP was far superior for enhancing the solubility of the passenger protein. Nevertheless, the effective yield after purification from the soluble fraction of both MBP-fusion and NT*-fusion was comparable, mainly due to higher expression levels in NT*-fusion and a smaller fraction of the passenger protein net weight being locked in the fusion protein. We conclude that NT* is an excellent fusion tag to improve the overall expression of globular proteins but does not increase the passenger protein’s solubility compared to MBP. Proteins that are partially soluble or can be refolded in-vitro will significantly benefit from N-terminal NT* fusions. The MBP, however, still remains one of the very few options for an N-terminal fusion if the solubility of the protein after expression is critical for preserving its proper fold or activity. This study involved multiple reactions and reactants, such as (2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1Related Products of 367-93-1).

(2R,3R,4S,5R,6S)-2-(Hydroxymethyl)-6-(isopropylthio)tetrahydro-2H-pyran-3,4,5-triol (cas: 367-93-1) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Related Products of 367-93-1

Bisphenol F (BPF) and bisphenol S (BPS) have replaced bisphenol A (BPA) in the manufacturing of products containing polycarbonates and epoxy resins; however, the effects of these substitutes on the risk of cardiovascular disease (CVD), including congestive heart failure, coronary heart disease, angina pectoris, heart attack, and stroke, have not been assessed. To examine the association of urinary BPS and BPF with CVD risk in a U.S. representative U.S. population. Cross-sectional data from 1267 participants aged 20-80 years from the 2013-2016 National Health and Nutrition Examination Survey (NHANES) were analyzed. Survey-weighted multiple logistic regression was used to assess the association between BPA, BPF, BPS and CVD. The Bayesian kernel machine regression (BKMR) model was applied to assess the mixture effect. A total of 138 patients with CVD were identified. After adjusting for potential confounding factors, the T3 tertile concentration of BPS increased the risk of total CVD (OR: 1.99, 95% CI 1.16-3.40). When stratified by age, we found that BPS increased the risk of CVD in the 50-80 age group (OR: 1.40, 95% CI 1.05-1.87). BPS was pos. associated with the risk of coronary heart disease, and the T3 tertile concentration of BPS increased the coronary heart disease risk by 2.22 times (95% CI 1.04-4.74). No significant association was observed between BPF and CVD. Although the BKMR model did not identify the mixed exposure effect of BPS, the risk of CVD increased with increasing compound concentration Our results suggest that BPS may increase the risk of total CVD and coronary heart disease in the US population, and prospective studies are needed to confirm the results.

The Platanus acerifolia (P. acerifolia) pollen is one of the most common causes of allergic respiratory symptoms in China. However, the allergenic components in P. acerifolia are not fully studied yet. The study aimed to determine the mol. and immunochem. characterization of the profilin from P. acerifolia pollen. The coding sequence of profilin was amplified, cloned, and then expressed in Escherichia coli BL21 cells and purified by nickel affinity chromatog. Protein refolding was followed by structural characterization and homol. 3D model building. The allergenicity and cross-reactivity were assessed by ELISA, immunoblotting, or basophil activation test (BAT) using the sera of P. acerifolia allergic patients. The cDNA sequence of profilin was cloned with a 396 bp open reading frame coding for 131 amino acids. The mol. weight of the profilin was approx. 14 kDa, and the predicted structure consisted of 3 α-helixes and 7 β-sheets. Physicochem. anal. indicated the profilin was a stable, relatively thermostable, and relatively conserved protein. The allergenicity determined by ELISA, western blot, and BAT suggested 76.9% (30/39) of the P. acerifolia pollen allergic patients displayed specific IgE recognition of the profilin. The profilin shared > 80% sequence identity with Pop n 2, the profilin from Populus nigra, and observed a significant cross-reactivity with Pop n 2 in IgE-inhibition assay. Profilin, as one of the major component allergens in P. acerifolia pollen, was identified and characterized at mol. and immunochem. levels in this study. These findings would contribute to developing diagnostic and therapeutic strategies for P. acerifolia pollen allergic patients.

Fe-nitrogen-doped carbon with dual active sites for efficient degradation of aromatic pollutants via peroxymonosulfate activation was written by Yu, Jianan;Zhu, Zhiliang;Zhang, Hua;Qiu, Yanling;Yin, Daqiang. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.COA of Formula: C13H12O2 The following contents are mentioned in the article:

Fenton-like catalysis has received much attention as the promising technol. for organic pollutant degradation, whereas it suffers from low at. utilization, poor catalysts durability and difficult after-treatment to hamper the catalytic oxidation activity. Herein, a Fe- and nitrogen-codoped carbon (Fe-N-C) originated from nanocellulose-based hydrochar, nitrogen source, and iron salt precursor was developed for improved PMS activation and identification of exclusive role of each species. The catalyst formed with interconnected bamboo-shaped 3D tubular structures and high Fe-doping level (up to ∼9.0 wt%) not only realized excellent efficiencies in oxidative degradation of various aromatic pollutants, but was also endowed with high durability and stability toward PMS activation. Compared with that of the control catalysts only comprising either C-N network or supported Fe nanoparticles (Fe-C) with FeIV-oxo complex sites, the co-existent active sites of Fe-N configuration and at. Fe cluster in Fe-N-C could simultaneously improve the graphitization degree, and act as a “support” for constructing the stable structure. It is likely that the coordinated Fe-N formed with annealing process is devoted to decompose PMS by radical generation for pollutants degradation via a radical oxidation process; while the enhanced C-N bonded with graphitic N contribute to produce 1O2 through the nonradical processes interacted with PMS. This Fe-N-C/PMS-coupled process provided a designed strategy to construct the highly active and stable metal-nitrogen-codoped hydrothermal carbons, and deepened insights on structure-activity-stability relationship for persulfate-based environmental remediation. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8COA of Formula: C13H12O2).
