Summary: This study used a transcriptomic approach to understand the molecular mechanism of aerobic decolorization of textile dyes by Pseudomonas aeruginosa D6. The results showed that the bacterium was able to decolorize four different dyes and exhibited unique behavior in the presence of dye TD01. Several genes related to core metabolic processes were found to be overexpressed in the presence of dyes, and the benzoate degradation pathway was significantly upregulated. Overall, the study suggests the appearance of aromatic intermediates during decolorization, indicating dye degradation.

Summary: A bioactive system using mineral poultice and aerobic denitrifier Pseudomonas stutzeri cells was developed to reduce nitrate content in brick and limestone, showing higher efficiency with strain P. stutzeri D1 compared to the reference strain. The biocleaning efficiency after 9 days of application was approximately 70% on the brick surface and 72% in depth using the reference strain, while it reached 95% with the natural isolate. The artificial neural network efficiently predicted the efficiency based on material layer depth, time, and bacteria type.

Summary: Iron oxide magnetic particles (PMag) synthesized via microwave heating and radiation, combined with laccases from white-rot fungi, were effective in removing Acid Blue 277 and Acid Black 172 dyes. While PMag showed high efficiency in low dye concentrations, Lac-PMag demonstrated superior removal capabilities at higher concentrations. The simultaneous process of adsorption and biodegradation by Lac-PMag proved to be an eco-friendly and economically efficient method for dye removal.

Summary: The exponential growth of industrial production has led to increased environmental pollution, particularly from chemical pollutants. Large volumes of agricultural byproducts, including wheat bran, are generated as waste materials. These waste materials have the potential to be used as adsorbents for dye and toxic effluent removal. Activated charcoal is commonly used as an adsorbent, but its high cost prompts the search for low-cost alternatives. Wheat bran has been found to have potential as an adsorbent for dye and toxic effluent removal. Adsorption and nano-materials offer promising methods for treating dye-laden water.

Summary: This study investigated the interactions between polyethylene MPs and the floating aquatic macrophyte Lemna minor. The results showed that the maximum number of adhered MPs was reached after 24 hours and increased with plant biomass. Slow water movement did not significantly affect MP adhesion. Among different adsorption models, the Freundlich adsorption isotherm model provided the best fit, suggesting weak binding of MPs to plant biomass. The study also found that 79% of MPs were removed during 15 cycles of phytoremediation, with an estimated 53 cycles needed to remove all MPs under test conditions.

Summary: This study successfully synthesized and characterized fluoride-doped-TiO2 and demonstrated its applicability in solid-phase photodegradation of polyethylene films for the first time. After three weeks of UV A radiation using a low consumption LED lamp, the polyethylene films containing only 2% of the photocatalyst experienced nearly 50% weight loss, surpassing previously reported data. The results suggest the potential for future production of self-photodegradable plastics for environmental and wastewater treatment applications.

Summary: The physical properties of choline glycylglycinate (ChGlyGly) were experimentally determined and the empirical values of density, refractive index, speed of sound and dynamic viscosity for aqueous and methanolic mixtures of this ionic liquid were ascertained at different temperatures. The derived values of the neat ChGlyGly and the corresponding mixtures were calculated. Polynomial fittings and Redlich-Kister model were used to describe the obtained and derived data, respectively. It is the first time that the density of the mixtures has been successfully predicted at several temperatures using different models.

Summary: Three CuFe-MOFs with different structures were synthesized successfully by varying the ratio of solvents, salts, or temperature. CuFe(BDC-NH2)(D) and CuFe(BDC-NH2)(S) exhibited improved PMS activation for Rhodamine B removal, achieving a removal rate of around 92%. The best degradation system for a mixture of antibiotic and anti-inflammatory drugs was the photo-assisted activation of PMS using CuFe(BDC-NH2)(D) and CuFe(BDC-NH2)(S), resulting in complete degradation within 1 hour. CuFe(BDC-NH2)(R)/PMS showed higher antibacterial activity due to its higher copper content.

Summary: In this study, the phase equilibria of CO2 hydrates in H2O, D2O, and their binary mixtures were investigated. The results showed that there is a difference in the equilibrium line of CO2 hydrates formed in H2O and D2O, but the hydrate dissociation enthalpies were similar. The study also revealed the influence of isotopic effect on CO2 hydrate formation and dissociation, which may have implications for separation and purification processes.
