In vitro biological properties of Streptomyces cangkringensis isolated from the floral rhizosphere regions

This context was investigated to determine in vitro antimicrobial, antioxidative, and anticancer traits of crude ethyl acetate extract of Streptomyces cangkringensis strain TSAS 04 isolated from soil sample of rhizosphere regions. The antimicrobial activity of ethyl acetate extract of strain TSAS 04 was determined against indicator pathogens using disc diffusion assay which exhibited maximum zones of inhibition of 20.6 +/- 0.3 and 16.3 +/- 0.6 mm against Bacillus subtilis and Trichoderma viride, respectively. In vitro antioxidant properties of the crude ethyl acetate extract were performed using standard methodologies. The extract revealed maximum DPPH_and ABTS?+ radical scavenging activities of 51.1 +/- 0.39 and 81.25 +/- 0. 33%, respectively. Likewise, maximum phosphomolybdenum reduction and Fe3+ reduction of the crude ethyl acetate extract of strain TSAS 04 were estimated 76.18 +/- 0.10 and 89.01 +/- 0.44%, respectively. In vitro anticancer trait of the extract was determined against HeLa cell line using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay which showed anticancer activities in a dose dependent manner with an IC50 value of 410.5 mu g/mL. Fourier transform infrared spectroscopy (FT-IR) and Gas chromatography-mass spectrometry (GC-MS) analyses indicated the presence of distinct functional groups and bioactive components in the extract, respectively. In conclusion, S. cangkringensis strain TSAS 04 showed its effectiveness as ideal bioactive agent by exhibiting substantial antimicrobial, antioxidant, and anticancer properties.

Effect of 1-hexanol on the phase behavior of SDS/CTAB/NaBr/H2O system

The influence of 1-hexanol on the phase behavior of sodium dodecyl sulfate (SDS)/cetyltrimethyl ammonium bromide (CTAB)/NaBr/H2O system has been systematically investigated in this paper. The results showed 1-hexanol effectively dissolved the precipitate formed by the CTAB and SDS surfactants, while liquid crystal (LC) and aqueous two phase system (ATPS) were formed in a wider range. When the molar ratio of 1-hexanol to surfactant is higher than 1, the precipitation in the system disappeared completely and was transformed into ATPS and LC, indicating that alcohol inserted at least evenly between every two surfactant molecules and hence effectively weakened the electrostatic interaction between the anionic and cationic surfactants and limited the formation of precipitation. Polarizing microscope (POM) with crossed polarizers was employed to investigate the textures of liquid crystals. It was shown that the existence of lamellar LC was confirmed by ?Maltese crosses? textures. Additionally, we showed that the thermal stability of LC was promising. The ATPS and LC regions remained stable and changed slightly when the temperature was increased from 40 to 70??C. The results indicated that ATPS and LC of the system were quiet resistant to temperature with the addition of 1-hexanol.

Band Gap Engineering in MASnBr(3) and CsSnBr3 Perovskites: Mechanistic Insights through the Application of Pressure

Here we report on the first structural and optical high-pressure investigation of MASnBr(3) (MA = [CH3NH3](+)) and CsSnBr3 halide perovskites. A massive red shift of 0.4 eV for MASnBr(3) and 0.2 eV for CsSnBr3 is observed within 1.3 to 1.5 GPa from absorption spectroscopy, followed by a huge blue shift of 0.3 and 0.5 eV, respectively. Synchrotron powder diffraction allowed us to correlate the upturn in the optical properties trend (onset of blue shift) with structural phase transitions from cubic to orthorhombic in MASnBr(3) and from tetragonal to monoclinic for CsSnBr3. Density functional theory calculations indicate a different underlying mechanism affecting the band gap evolution with pressure, a key role of metal-halide bond lengths for CsSnBr3 and cation orientation for MASnBr(3), thus showing the impact of a different A-cation on the pressure response. Finally, the investigated phases, differently from the analogous Pb-based counterparts, are robust against amorphization showing defined diffraction up to the maximum pressure used in the experiments.

Inhibition of bromate formation by reduced graphene oxide supported cerium dioxide during ozonation of bromide-containing water

Ozone (O-3) is widely used in drinking water disinfection and wastewater treatment. However, when applied to bromide-containing water, ozone induces the formation of bromate, which is carcinogenic. Our previous study found that graphene oxide (GO) can enhance the degradation efficiency of micropollutants during ozonation. However, in this study, GO was found to promote bromate formation during ozonation of bromide-containing waters, with bromate yields from the O-3/GO process more than twice those obtained using ozone alone. The promoted bromate formation was attributed to increased hydroxyl radical production, as confirmed by the significant reduction (almost 75%) in bromate yield after adding t-butanol (TBA). Cerium oxide (less than 5 mg/L) supported on reduced GO (xCeO(2)/RGO) significantly inhibited bromate formation during ozonation compared with reduced GO alone, and the optimal Ce atomic percentage (x) was determined to be 0.36%, achieving an inhibition rate of approximately 73%. Fourier transform infrared (FT-IR) spectra indicated the transformation of GO into RGO after hydrothermal treatment, and transmission electron microscope (TEM) results showed that CeO2 nanoparticles were well dispersed on the RGO surface. The X-ray photoelectron spectroscopy (XPS) spectra results demonstrated that the Ce3+/Ce4+ ratio in xCeO(2)/ RGO was almost 3-4 times higher than that in pure CeO2, which might be attributed to the charge transfer effect from GO to CeO2. Furthermore, Ce3+ on the xCeO(2)/RGO surface could quench Br center dot and BrO center dot to further inhibit bromate formation. Meanwhile, 0.36CeO(2)/RGO could also enhance the degradation efficiency of N,N-diethyl-m-toluamide (DEET) in synthetic and reclaimed water during ozonation.

Emulsion based solvothermal synthesis of CuO grainy rod via the formation of quasi-quadrangular prism shaped Cu-2(OH)(3)Br for recyclable catalyst of 4-nitrophenol reduction

Quasi-quadrangular prism shaped Cu-2(OH)(3)Br particles were synthesized by emulsion based solvothermal process followed by their transformation to hierarchical copper oxide grainy rods by calcination at 450 degrees C/2 h. In this process, we employed cetyltrimethyl ammonium bromide (CTAB) as cationic surfactant as well as bromide source, 1-butanol as co-surfactant, cyclohexane as organic (oil) medium, copper acetate as aquo-based copper precursor and hexamethylenetetramine ((CH2)(6)N-4) as the source of ammonia under hydrolyzing condition. The length/diameter of hierarchical CuO grainy rods was found to be around 2.5-10 mu m/0.5-1.5 mu m comprising of smaller grain (20-30 nm) assembly. The proposed reaction trajectory based on anion-exchange mechanism was proposed for the transformation of Cu-2(OH)(3)(CH3COO) to Cu-2(OH)(3)Br. The product showed excellent catalytic performance for 4-nitrophenol reduction. The apparent rate constant values increased from 0.532 min(-1) to 1.038 min(-1) with catalyst amount increased from 1 to 3 mg. This investigation refers the novel synthesis approach of CuO grainy-rod from quasi-quadrangular prism shaped Cu-2(OH)(3)Br precursor, and its role as catalyst for 4-nitrophenol reduction.

MMP-2 and MMP-9 mediate cigarette smoke extract-induced epithelial-mesenchymal transition in airway epithelial cells via EGFR/Akt/GSK3 beta/beta-catenin pathway: Amelioration by fisetin

Matrix metalloproteinases (MMPs) have been implicated in EMT but their role in the regulation of cigarette smoke-induced EMT in airway epithelium is not clear. We have therefore investigated the potential role of MMP2 and -9 in cigarette smoke extract (CSE) induced EMT using A549 lung epithelial cells and human small airway epithelial cells (SAEC). The cells were treated with different concentration of CSE, and MTT and trypan blue assays, acridine orange-ethidium bromide assay, gelatin zymography, Western blotting, immunofluorescence studies, Boyden-chamber assay, wound healing assay and air-liquid interface (ALI) culture were used to assess different cellular and molecular changes associated with EMT. The results depict that CSE increased the cytotoxicity along with a concurrent increase in the expression and activity of MMP-2 and -9. CSE further altered EMT markers like E-cadherin, N-cadherin, vimentin, and the molecular modulators of EMT such as beta-catenin and pGSK-3 beta. Further, CSE also upregulated EGFR, AKT, and ERK1/2 in airway epithelial cells. SB-3CT, a known inhibitor of MMP-2 and -9, altered and reversed the expression of markers of EMT and kinases, validating the role of MMP-2 and -9 in CSE-induced EMT. Fisetin, a plant-derived bioflavonoid, also reversed the expression of EMT markers and molecular regulators in a similar fashion as SB-3CT. In summary, this study highlights the role of MMP-2 and -9 in CSE-induced EMT and curate its molecular cascade through EGFR/AKT/ERK/beta-catenin axis, which could be restored by MMP-2 and -9 inhibitor and fisetin. Fisetin is hitherto unknown to modulate CSE-induced MMPs activity in airway epithelial cells, and our study suggests its potential role as a therapeutic approach in CSE-induced EMT in lung epithelial cells.

Process Simulation and Economic Analysis of Pre-combustion CO2 Capture With Deep Eutectic Solvents

The purpose of this paper is to identify firstly the most important solvent characteristics in the CO2 capture process and secondly to determine how they contribute to the total cost of CO2 separation and analyze the economic feasibility of current deep eutectic solvents (DESs) in literature. A rate-based modeling approach was adopted to simulate pre-combustion CO2 capture. The effects of the flow model and the number of segments were investigated for the Selexol process. Different mass transfer correlations due to Bravo et al. (1985), Billet and Schultes (1993) and Hanley and Chen (2012) were adopted for the rate-based models and compared with the equilibrium modelling approach. Subsequently, property and process models were developed for a mixture of decanoic acid and menthol, in equal quantities. A physical property study was conducted with this DES. The CO2 solubility is found to be very important in all rate-based models, as expected, but properties such as the surface tension, thermal conductivity, heat capacity and volatility had a minor influence on the absorption performance. The solvent viscosity strongly affects the mass transfer rate when using the Hanley and Chen (2012) correlations, whereas it plays only a small role in the other two sets of correlations. Using a high CO2 solubility as criterion, two mixtures of allyl triphenylphosphonium bromide (ATPPB) and diethylene glycol (DEG) were screened out from literature. The conventional Selexol process was set as the benchmark for the evaluation of the performances of these DESs. The optimum capture cost for Selexol process is 27.22, 26.66 and 30.84 $(2018)/tonne CO2 for the adopted correlations, respectively. When employing two of the three studied mass transfer correlations, the estimated process costs for a capture process using this DES can be similar to the costs of the Selexol process. However, when the liquid viscosity strongly affects the mass transfer rate, as is the case when using the Hanley and Chen (2012) correlations, the Selexol process remains more economical. This strongly indicates the need for further experimental and modelling studies on mass transfer rates in absorption columns (with higher viscosity liquids) to help directing the development of suitable DESs for pre-combustion CO2 capture.

Recent Advances in Experimental Measurements of Mixed-Gas Three-Phase Hydrate Equilibria for Gas Mixture Separation and Energy-Related Applications

Clathrate hydrates are currently studied extensively due to their involvement in important industrial processes. For certain industrial applications (e.g., flow assurance in oil/gas industry), they are considered a nuisance and their presence needs to be either suspended completely or adequately controlled. On the other hand, for other industrial applications (e.g., gas mixture separation, water desalination, and purification), hydrate formation is sought after, since it can facilitate the desired outcome. In either case, it is essential to have reliable values for the hydrate equilibrium conditions, in order to design appropriately the corresponding industrial applications. In the current study, we review the experimental studies that have reported three-phase hydrate equilibrium measurements. We focus primarily on studies that were published after the year 2008. Furthermore, we report only studies that examine the gas mixtures of two or more components. Of primary interest are gas mixtures that have significant industrial applications and include components such as carbon dioxide, nitrogen, hydrogen, methane, ethane, propane, hydrogen sulfide, and oxygen. The examined mixtures include at least one of the aforementioned gases. Of particular interest in this review are applications such as gas mixture separation (where hydrate promotion is desirable) and energy-related application such as flow assurance during oil/gas production and transportation (where hydrate inhibition is desirable). The mixtures that are included in the review are grouped under 15 gas mixture types. For most of the gas mixtures that are examined, the related industrial applications are identified and briefly discussed. In the current review, the different gas mixtures are also critically discussed and suggestions for possible future directions are presented regarding the examination of tentative additives to be used for promotion or inhibition.
