Summary: In this study, cadmium and nickel resistant bacteria were isolated from an industrial factory in Iran, and their biosorption efficiency was optimized using single-factor and central composite design methods. The analysis revealed that under the conditions of pH 7.0, 45 degrees C, and 1.5 g/L biomass dose, the biosorption efficiency for cadmium and nickel by the bacteria reached 92.43% and 88.45% respectively. The study also confirmed the adsorption of heavy metal ions by the bacterial biomass through Fourier transform infrared spectroscopy, scanning electron microscopy, and energy-dispersive X-ray spectroscopy.

Summary: This study uses Pseudomonas putida strains isolated from activated sludge to reduce the organic compound content and dark color of biogas plant effluent. The treatment of effluent from distillery wastewater anaerobic digestion with P. putida showed significant decolorization and organic removal efficiencies of 34.29% and 38.94%, respectively. The naturally selected bacterium can tolerate high levels of organic content and work synergistically with other microorganisms in the biogas plant effluent.

Summary: In this study, the operation parameters of partial nitrification (PN) treating saline wastewater were optimized using the Box-Behnken design and response surface methodology (BBD-RSM). A control strategy based on carbon/nitrogen ratio (C/N), alkalinity/ammonia ratio (K/A), and salinity was used to achieve high and stable PN. The optimized process showed improved ammonia removal efficiency (ARE) and nitrite accumulation rate (NAR) compared to the nonoptimized process. The developed regression model accurately predicted the PN performance under optimal conditions.

Summary: This study focused on the emissions of Pseudomonas sp. in bioaerosols from a WWTP and their inactivation through UV radiation. High-throughput sequencing was used to analyze microbial population and functional composition. The study found that bioaerosol emissions showed site-related and temporal variation. Exposure to UV radiation led to a significant decrease in bioaerosol concentrations in the air.

Summary: This study aimed to extract TPCs efficiently from olive mill wastewater. The best extraction conditions were found to be using 80% ethanol at 25 degrees C and 2.5 bar, with a pH of 4. Temperature had the greatest impact on the extraction of TPC and TAA, while the pH factor had the least effect. The response surface method (RSM) proved to be a useful tool for assessing the ideal circumstances for phenolic component extraction.

Summary: In this study, the response-surface methodology (RSM) was used to optimize the synthesis of a Mg-doped UiO-66-NH2 nanocomposite for enhanced phosphate removal. The optimized parameters for the nanocomposite fabrication were determined to be a magnesium concentration of 1.18 mM, solvothermal temperature of 120 degrees C, and solvothermal time of 12.69 h. The optimal sample showed a P removal efficiency 1.75 times higher than that of pristine UiO-66-NH2. Analysis of the adsorbent revealed that the P removal process was primarily based on chemical interactions. Furthermore, the adsorbed P could be effectively recovered using different concentrations of sodium hydroxide.

Summary: In this study, the degradation of Orange IV (O-IV) under ultraviolet (UV) light-induced conditions in the presence of nitrite (NO2-) in an aqueous solution was investigated. The rate constants of O-IV degradation (k(obs)) were evaluated by considering various influencing factors, such as initial concentration of O-IV, light intensity, temperature, pH, NO2- concentration, and inorganic anions. The results revealed that O-IV was effectively removed at a k(obs) of 0.05268 min(-1) in the UV/NO2- system. The active species responsible for the degradation were determined to be hydroxyl radical (OH) and singlet oxygen (O-1(2)), as confirmed by quenching experiments and electron paramagnetic resonance (EPR) spectroscopy. The study also proposed a possible photodegradation mechanism of O-IV using liquid chromatography-mass spectrometry (LC-MS) analysis.

Summary: Agro-industrial residues, such as fruit pomaces, are potential sources for the development of materials and food supplements. This study demonstrates the production of antimicrobial oligomers from cutin-rich materials isolated from tomato pomaces. The chemical composition of the pomaces and the corresponding cutin-rich materials were analyzed, and the resulting mixtures were screened for bactericidal activity. Esterified structures were found to be essential for activity against Escherichia coli, while monomers were effective against Staphylococcus aureus.

Summary: Long-term exposure to ambient ultrafine particles increases the risk of neurodegenerative diseases like Alzheimer's disease. This study used molecular dynamics simulations to investigate the effect of polycyclic aromatic hydrocarbons (PAHs) on the formation of A beta(42) oligomers. It was found that a specific PAH, Benzo[a]Pyrene (B[a]P), accelerated the formation of oligomers, while other concentrations of B[a]P suppressed the oligomerization process.

Summary: Bone and energy metabolism are integrated through common regulatory mechanisms. PPAR alpha nuclear receptor controls the bioenergetics and mitochondrial response of osteocytes, contributing to systemic energy metabolism and regulating bone microenvironment and peripheral fat metabolism. Aging and impaired lipid metabolism in PPAR alpha deficient osteocytes lead to a low-energy phenotype and obesity, but do not affect bone phenotype.

Summary: This study analyzed the thermochemical properties of sewage sludge and conducted experiments on the co-combustion of sewage sludge and coal. The results showed that the calorific value of the sludge sample was comparable to that of coal samples, and there were differences in NOx emissions between mono-combustion and co-combustion processes. The findings of this study are valuable for developing sustainable disposal methods for municipal sewage sludge.

Summary: The study found that the presence of CeF3 nanoparticles affects the secondary structure of Aβ peptides, promoting the formation of a beta-sheet structure. This phenomenon is mainly attributed to the hydrophobic interaction between the NPs and Aβ peptides, leading to the peptides aggregation on the NP surface and forming ordered hydrogen bonds. In addition, the presence of NH4+ and NO3- ions also influences the assembly and structure formation of Aβ peptides.
