Summary: In this study, the removal of the recalcitrant azo dye reactive yellow 145 (RY145) was achieved through sequential treatment using zero valent aluminum (ZVAl) and bacterial degradation. The ZVAl pretreatment resulted in significant decolorization, followed by microbial degradation of the intermediates. The combined treatment exhibited high efficiency in dye decolorization and organic compound degradation, addressing the challenges posed by RY145.

Summary: The study compared the degradation of iprodione (IPR) by UV-C light, zero-valent iron (ZVI), and zero-valent aluminum (ZVA) activated persulfate (PS) oxidation processes in distilled water (DW) and simulated urban wastewater (SWW). The results showed that ZVI/PS treatment was the most effective oxidation process in SWW, with the treatment performance being strongly influenced by the constituents of SWW, and UV-C/PS treatment being the most sensitive to it.

Summary: The technology of permeable reactive barriers is a reliable and cost-effective method to prevent the spread of pollutants in groundwaters. In this study, sulfidated zero-valent iron synthesized by ball-milling is proposed as a barrier filling material to activate persulfate for the removal of reduction-resistant organic pollutants. The experiments demonstrated the rapid degradation of atrazine, a model pollutant, and the superior efficiency of sulfidated iron compared to zero-valent iron. The study also found that coexisting ions have a negative influence on both atrazine and its byproducts.

Summary: White rot fungi can secrete extracellular oxidases for lignin degradation, and using bioabsorbent with ligninolytic macrofungal mycelium on PET-coated SBS paper can effectively remove colorants like Remazol Brilliant Blue Reactive dye. High carbon and nitrogen concentrations result in bioadsorbents with increased protein and enzymatic activity, leading to 94% color removal of RBBR dye over 30 days. The bioadsorbent presents a potential efficient and low-cost solution for decolorizing dyes and textile effluents.

Summary: Azo dyes, widely used in textile industries, are difficult to degrade due to their xenobiotic nature. However, recent studies have shown that many microorganisms can convert these toxic azo dyes to non-colored compounds or even mineralize them under specific environmental conditions. This study evaluated the decolorizing efficiency of newly isolated Paramecium species in textile industrial wastewater containing azo dyes. The results showed that Paramecium species had a high decolorization rate under optimum conditions, making them potentially useful for bioremediation of textile-dying industry effluents.

Summary: This study aimed to enhance the bioavailability of rosmarinic acid, a bioactive compound with high anticancer activity, by encapsulating it in tetrasulfide-based porous organosilica nanoparticles. The synthesized nanoparticles were small in size and had a high surface area and an average pore diameter. The nanoparticles showed effective accumulation in cancer cells without toxicity to normal cells. Treatment with rosmarinic acid-containing nanoparticles resulted in significant cell death in cancer cells. Overall, these findings suggest that the synthesized nanoparticles can enhance the pharmacological effects of rosmarinic acid.

Summary: Plasma protein binding plays a crucial role in the pharmacokinetics and pharmacodynamics of therapeutic bioactive materials. In this study, the interaction of nordentatin, a member of coumarins, with human alpha-1 acid glycoprotein (AGP) was investigated, and the anticancer potency of nordentatin against human colorectal cancer cells was evaluated. The results showed that nordentatin binds to AGP through a static quenching mechanism and exhibits inhibitory effects on the growth of HCT-116 cells by increasing intracellular ROS and [Ca2+] levels and triggering apoptosis-related gene overexpression. Therefore, nordentatin could be a promising plant-based therapy for colorectal cancer.
