The reductive capacity of microbial extracellular polymeric substances (EPS) plays important roles in environmental processes involved in heavy metal detoxification and organic contaminant degradation However, the crucial parameter to evaluate the reductive capacity of EPS, electron donating capacity (EDC) lacks a quant. approach. In this study, a novel mediated electrochem. oxidation (MEO) method was developed to investigate the EDCs of microbial EPS extracted from Shewanella oneidensis MR-1 (S. oneidensis MR-1), Escherichia coli (E. coli) and activated sludge. The results indicate that the MEO approach rapidly and accurately quantifies the EDCs of microbial EPS. S. oneidensis MR-1 EPS possessed the highest EDC value ascribed to their specific redox proteins components. EDCs of S. oneidensis MR-1 EPS were dependent on measurement conditions and increased with growing solution pH and applied potential. EDCs of S. oneidensis MR-1 EPS were depleted gradually during the redox reaction with irreversible oxidation of EPS. The reductive property of microbial EPS was accurately evaluated by quantifying the EDCs of EPS using the MEO approach, as well as their potential in environmental remediation.ABTS Diammonium(cas: 30931-67-0Recommanded Product: 30931-67-0) was used in this study.

The article was titled 《Free radical-mediated conjugation of chitosan with tannic acid: Characterization and antioxidant capacity》, and you may find the article in Reactive & Functional Polymers.Related Products of 30931-67-0 The information in the text is summarized as follows:

Chitosan (CS) is a natural biopolymer with versatile applications. In this work, CS was functionalized with tannic acid (TA) by a free radical grafting procedure to improve its antioxidant capacity. The resulting TA-conjugated CS (TA-CS) showed a high TA equivalent content of 267.1 ± 5.4 mg TAE/g. The formation of TA-CS was verified by UV-vis, FTIR, and 1H NMR analyses. Moreover, TA-CS showed a lower thermal stability and crystallinity than CS and exhibited a good water-solubility of 15.0 ± 0.3 mg/mL. The DPPH radical scavenging activity of TA-CS reached a maximum of 91.6%, which was 6.4-fold higher than that of CS. Similar results were also observed in ABTS and hydroxyl radical scavenging assays. Moreover, TA-CS showed a higher superoxide radical scavenging activity and ferrous ion chelating activity than both TA and CS. These results suggest that conjugating with TA is an available way to enhance the antioxidant capacity of CS.

The title of the article was 《Production of Red Pigments by a Newly Isolated Talaromyces aurantiacus Strain with LED Stimulation for Screen Printing》.Related Products of 30931-67-0 The author mentioned the following in the article:

Microbial pigments have been widely applied to printing in food, textile, and paper industries as a sustainable alternative to synthetic dyes. Herein, we isolated a novel Talaromyces aurantiacus strain with a strong ability to produce red pigments. We further studied pigment production conditions, stability, screen printing application, and bioactivities. Our results showed that sucrose was a favorable carbon source and the addition of L-histidine significantly enhanced the production of red pigments. Pigment production was strictly photo-regulated with effective wavelengths around 450 nm (blue light). We mixed the red pigments with cellulosic materials and explored their application potentials for screen printing on paper, cotton fabrics, and polymeric carriers. The printing d. was significantly improved from 0.3 to 0.7 by overlay printing. T. aurantiacus pigments could be stably stored at pH 5-11, temperature – 10 to 70°C, and redox potential – 200 to 300 mV. Moreover, the stable ranges were extended to pH 1-11 and temperature over 100°C after screen-printed on paper. The red pigments exhibited antioxidant activity toward 2,2′-Azinobis-(3-ethylbenzthiazoline-6-sulfonate) (IC50 10.4 mg L-1 in solution). Our results further indicated the red pigments by T. aurantiacus was environmentally friendly based on acetylcholinesterase activity assay.

《Bee Pollen Extracts as Potential Antioxidants and Inhibitors of α-Amylase and α-Glucosidase Enzymes In Vitro Assessment》 was published in Journal of Apicultural Science in 2019. These research results belong to Daudu, Oluremi M.. Recommanded Product: ABTS Diammonium The article mentions the following:

The study was conducted to determine the antioxidant and anti-diabetic properties of bee pollen. The phenol content of extracts was 1.43, 2.04, 2.10 and 1.79 mg gallic acid g-1, resp. Total flavonoid content was 0.78, 1.39, 0.86 and 0.79 mg gallic acid g-1 resp. Bee pollen extracts have the potential to scavenge free radicals and lower blood glucose due to the presence of phenols and flavonoids. The aqueous-ethanol extract had the lowest IC50 for HRS and TAC, 0.53mg/mL and 0.25mg/mL resp., which depicts that this extract alleviates the destructive effect of hydroxyl radicals. Methanol extract had the lowest IC50 (0.21 mg/mL) for DPPH inhibition, hence it was able to scavenge the DPPH radicals. Ethanol extract had the lowest IC50 (0.04 mg/mL) for 2, 2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) inhibition, hence it can protect living cells from ABTS cations. The aqueous-ethanol extract displayed higher inhibition of α-amylase (4.51 mg/mL) while the aqueous extract exhibited a higher inhibition of α-glucosidase (0.60 mg/mL), which slows down the breakdown of disaccharides and reduces sugar buildup in the bloodstream. Bee pollen has potential antioxidative and antidiabetic activity.

Saha, Rituparna; Mukhopadhyay, Mainak published an article on January 31 ,2022. The article was titled 《Electrochemical analysis of Catechol polymerization in presence of Trametes versicolor laccase and the mediator ABTS》, and you may find the article in Enzyme and Microbial Technology.Formula: C18H24N6O6S4 The information in the text is summarized as follows:

The phenolic compound catechol has found various applications in the industry but is often discharged untreated in industrial effluents. Catechol is highly toxic and adversely affects the environment. This has increased extensive investigation into elucidating the effects of various synthetic elements or different biocatalysts on catechol, thereby leading the way to its bioremediation. Hence, an electrochem.-based study on catechol in the presence of the enzyme laccase could provide a basic understanding of the unique characteristics exhibited by catechol, thus facilitating a distinct perspective to its subsequent treatment and removal. The present study focuses on the electrochem. characterization of catechol based on the oxidation of laccase and the redox mediator 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Catechol exhibited distinct electrochem. behavior across various concentrations The unique electroactive nature of ABTS assisted in the polymerization of catechol which was found to be concentration-dependent. Laccase produced a higher oxidation-reduction rate, thereby producing a much more stable condition for the polymerization of catechol. However, with the laccase-mediator system (LMS), the catechol polymerization rate was distinctly higher and more gradual with the enzyme utilizing the electroactive species produced by ABTS to increase the electron transfer and producing a combinatorial impact on the phenolic compound This study could rightly serve as the building block in developing future technologies like wastewater treatment and biosensors for catechol bioremediation.

In 2021,New Journal of Chemistry included an article by Borthakur, Priyakshree; Boruah, Purna K.; Das, Punamshree; Das, Manash R.. Computed Properties of C18H24N6O6S4. The article was titled 《CuS nanoparticles decorated MoS2 sheets as an efficient nanozyme for selective detection and photocatalytic degradation of hydroquinone in water》. The information in the text is summarized as follows:

The development of cost effective and efficient nanomaterials with enzyme mimetics and photocatalytic activity has achieved tremendous research interest in the quant. detection as well as removal of toxic environmental pollutants. CuS nanoparticles decorated MoS2 sheets were successfully synthesized adopting a simple hydrothermal technique and using low-cost materials. The nanocomposite was successfully used as an efficient catalyst for the selective detection and removal of a toxic phenolic compound like hydroquinone (HQ). The CuS-MoS2 nanocomposite catalyzed the oxidation of different chromogenic substrates like 3,3′,5,5′-tetramethylbenzidine, 2,2′-azino-bis(3-ethylbenzo-thiazoline-6-sulfonic acid)diammonium salt, and o-phenylenediamine in the presence of H2O2, indicating its peroxidase-like activity as natural Horseradish peroxidase (HRP). The catalytic performance of the nanozyme was further investigated through the typical Michaelis-Menten kinetics. The results showed that the proposed sensor exhibited improved catalytic properties with a wide linear relationship (0.4-50μM) and a low detection limit of 3.68μM for HQ detection in aqueous medium. Meanwhile, the mechanism of HQ sensing in the presence of CuS-MoS2 nanozyme was systematically investigated. Moreover, the CuS-MoS2 nanozyme possessed significant photocatalytic activity and 83% HQ decomposition was achieved within 240 min under irradiation of natural sunlight. The mechanism of enhanced photocatalytic degradation of HQ through the formation of OH radicals as reactive species was evidenced by analyzing the formation of fluorescent active mols. on the addition of terephthalic acid and by high-resolution mass spectrometry. Thus CuS-MoS2 represents a new and promising HQ sensing material in a highly sensitive and fast manner as well as an efficient photocatalyst for the degradation of HQ to its non-toxic products under natural sunlight irradiation The experimental part of the paper was very detailed, including the reaction process of ABTS Diammonium(cas: 30931-67-0Computed Properties of C18H24N6O6S4)

In 2021,Journal of Veterinary Research included an article by Szponder, Tomasz; Zdziennicka, Joanna; Nowakiewicz, Aneta; Swieca, Michal; Sobczynska-Rak, Aleksandra; Zylinska, Beata; Patkowski, Krzysztof; Junkuszew, Andrzej; Wessely-Szponder, Joanna. Formula: C18H24N6O6S4. The article was titled 《Effects of topical treatment of foot rot in sheep using ozonated olive ointment》. The information in the text is summarized as follows:

Foot rot in small ruminants is highly contagious, causes severe lameness, and impairs fertility and wool and meat production It is usually treated with parenteral antibiotics, with attendant antibiotic resistance risk, and with bactericidal footbaths, potentially harmful to humans and the environment. An alternative treatment in sheep is proposed based on repeated topical ozonated ointment application. Its effectiveness and safety were evaluated by estimation of acute-phase response, biochem. indicators of organic damage, and antioxidant/oxidant balance (AOB). The study was conducted on ten sheep with Egerton scale 2-3 lesions. Ozone application was repeated every day for seven days. Blood was drawn first (T0) after foot cleaning and before ozonation, then (T1) seven days after the first ozone application, and finally (T2) four days after the last application. High clin. effectiveness was observed, with total recovery by 28 days from the start of treatment. A significant increase in antiradical activity was noted on the basis of a 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assay from 1.16 ± 0.04 μmolTe/mL at T0 to 1.23 ± 0.03 μmolTe/mL at T1, with a slight decrease in oxidative stress. Calculated on the basis of antiradical capacity, AOB was higher at T1 (130 ± 19%) and decreased to 110 ± 16% at T2. Calculated on the basis of reducing power, it was 169 ± 22% at T1 and 131 ± 17% at T2. These results indicated that the AOB is efficient enough to prevent oxidative organ injury and the applied doses of ozone are safe for animals.

Wang, Hefei; Zhao, He-Ping; Zhu, Lizhong published an article in Environmental Science & Technology. The title of the article was 《Role of Pyrogenic Carbon in Parallel Microbial Reduction of Nitrobenzene in the Liquid and Sorbed Phases》.Name: ABTS Diammonium The author mentioned the following in the article:

Surface functional groups and graphitic C comprise the electroactive components of pyrogenic C. The role of pyrogenic C with different electroactive components content in mediating electron transfer in biochem. reactions has not been systematically studied. The authors determined the pyrogenic C electron exchange capacity was 0.067-0.120 mmol e-/g pyrogenic C with maximum elec. conductivity (EC) of 4.85 S/cm. Nitrobenzene was simultaneously reduced in liquid and sorbed phases by Shewanella oneidensis strain MR-1 in the presence of pyrogenic C. Pyrogenic C did not affect aqueous nitrobenzene reduction; reduction of sorbed nitrobenzene was much slower than that of the aqueous species. Enhancing the pyrogenic C oxygenated functional moiety content by HNO3 oxidation elevated bio-reduction rates of aqueous and sorbed species. Anthraquinone groups were deemed the most likely oxygenated functional redox compounds based on voltammetric curve tests and spectroscopic anal. Pyrogenic C reactivity for mediating sorbed nitrobenzene reduction was pos. correlated with its EC, which was demonstrated to be related to condensed aromatic structures. This work elucidated the mechanism for pyrogenic C-mediated biotransformation of nitrobenzene and helped properly evaluate the pyrogenic C role in biogeochem. redox processes occurring in nature.

Tungstate based nanomaterials have emerged as important class in transition metal oxide. In this study, Lead tungstate (PbWO4) nanostructures with lamellar morphol. were prepared by hydrothermal method. The synthesized materials were characterized by XRD, SEM, FTIR, DLS, BET and PL. Nitrogen adsorption-desorption measurements indicated that the surface area of the synthesized lamellar morphol. was ∼86.225 m2 g-1. The lamellar-like morphol. showed enhanced peroxidase-like activity owing to the large surface area, higher substrate interaction and efficient electron transportation. The results indicated higher reaction velocity (Vmax = 13.56 × 10-8 M s-1) and low Michaelis-Menten constant (km = 0.325 mM) value for nanostructures, providing evidence for higher affinity of novel structures towards the substrate and increased peroxidase-like activity.
