“…Meanwhile, the relative peak area of the β-sheet structure generally increased for samples after treatment with La-coated ceramic materials. Such an increase suggested the transformation of the protein secondary structure from the compact α-helix to the loose β-sheet structure, which could result in the formation of protein aggregates and disturbance of protein functions. , Similar alteration of the protein secondary structure was also observed for cells under stress from xenobiotic contamination (e.g., imidazolium-based ionic liquid, antibiotics, and perfluorooctanoic acid), ,, which induced obvious cell toxicity. Additionally, a new peak (1774 cm –1 ) associated with the protonated carbonyl group from Glu and Asp was observed after La-coated ceramic material treatment, which might be induced when cells were under oxidative stress or damage. , The FTIR results indicated that the La-coated ceramic could induce the virion capsid protein conformational changes and lead to the capsid functional or structure damage, which in turn might cause more viral genome release and accelerate their degradation.…”

Ceramic water filters (CWFs) are widely utilized as a low-cost and effective point-of-use (POU) drinking water treatment technology in developing countries for the removal of pathogenic microorganisms. However, CWFs generally showed low removal efficiency for waterborne virus which poses a high health risk. In this study, we employed a novel lanthanum (La) coating for CWFs to enhance viral removal. Compared to the negligible viral removal of raw CWFs (<0.2 log), CWFs with La coating prepared at 600 °C effectively treated ∼10,000 pore volumes of virus-contaminated water without the detection of any infective virus in the effluent (∼5 log removal). Its equivalent treatment volume is expected to surpass the treated volume of a commercial CWF in the whole service lifespan. The characterization of La-coated ceramic, combined with analysis of the extended Derjaguin–Landau–Verwey–Overbeek energy profiles and inactivation kinetic tests, indicated that the enhanced viral removal by La-coated CWFs may be attributed to the increased attachment of virus onto the filter surface due to the reduction of the repulsive energy barrier and the presence of secondary energy minimum, as well as the inactivation nature of La-coated ceramic. These processes minimized the risk of remobilization and release of infective virus from ceramic filters, further confirming by the desorption test. Furthermore, the viral genome and biospectroscopic analysis suggested that both genome damage and protein capsid conformational changes caused the viral inactivation by La-coated ceramic. Our finding showed that La-coated CWFs may represent a promising practical POU treatment solution for viral removal particularly suited for developing countries. The results also provided fundamental insights into the interactions between La species and virions, which may advance the research on La application for water treatment.

“…It can be seen from Table S2 † that the protein structure in leaves changed from α-helix to β-sheet at 100 and 250 mg L −1 , and the c-TiO 2 NP treatment showed a stronger response. Normally, the transition from α-helix to β-sheet is considered a form to resist oxidative stress in adversity, such as antibiotic, 39 perfluorooctanoic acid, 40 perfluorooctane sulfonic acid stress, 41 etc. The α-helix is more compact to enhance protein tolerance of external disturbances, while the loose β-sheet provides more redox active sites, which can lead to oxidative damage of protein.…”

Microorganisms produce siderophores, which are secondary metabolites with a high affinity for iron. Siderophores have received significant attention due to their diverse applications in ecological and clinical research. In this study, siderophores production by Escherichia coli OQ866153 was optimized using two-stage statistical approach involving Plackett–Burman design (PBD) and response surface methodology (RSM) using central composite design (CCD). Out of 23 variables, succinate, tryptophan, Na2HPO4, CaCl2, agitation, and KH2PO4 were found to have the most significant effect on siderophores production in the first optimization stage with the highest SU% of 43.67%. In the second stage, RSM using CCD was utilized, and the optimal conditions were determined to be 0.3 g/l succinate, 0 g/l tryptophan, 6 g/l Na2HPO4, 0.1 g/l CaCl2, 150 RPM agitation, and 0.6 g/l KH2PO4, resulting in a maximum siderophore units (SU%) of 89.13%. The model was significant, as indicated by the model f-value of 314.14 (p-value = 0.0004) and coefficient of determination R2 of 0.9950. During validation experiments, the obtained maximum SU% was increased up to 87.1472%, which was two times as the value obtained under ordinary conditions (46.62%). The produced siderophores were purified and characterized using 1H, 13C NMR, IR spectroscopy. The obtained results indicated that the compound was enterobactin and entABCDEF genes were further detected in Escherichia coli OQ866153 extracted DNA. To our knowledge, this is the first report of statistical optimization for enterobactin synthesis by an E. coli strain isolated from a clinical source in Egypt.
