Synthesis and characterization of innovative GA@Ag-CuO nanocomposite with potent antimicrobial and anticancer properties.

Cancer and microbial infections place a significant burden on the world's health systems and can increase the rate of disease and mortality. In the current study, a novel nanocomposite based on Gum Arabic, silver and copper oxide nanoparticles (GA@Ag-CuO nanocomposite) was synthesized to overcome the problem of microbial infection and in cancer treatment. Characterization using UV-Vis.

Unraveling the degradation mechanism of multiple pyrethroid insecticides by Pseudomonas aeruginosa and its environmental bioremediation potential.

Extensive use of pyrethroid insecticides poses significant risks to both ecological ecosystems and human beings. Herein, Pseudomonas aeruginosa PAO1 exhibited exceptional degradation capabilities towards a range of pyrethroid family insecticides including etofenprox, bifenthrin, tetramethrin, D-cypermethrin, allethrin, and permethrin, with a degradation efficiency reaching over 84 % within 36 h (50 mg·L). Strain PAO1 demonstrated effective soil bioremediation by removing etofenprox across different concentrations (25-100 mg·kg), with a degradation efficiency over 77 % within 15 days.

Exploring the sources, occurrence, transformation, toxicity, monitoring, and remediation strategies of per- and polyfluoroalkyl substances: a review.

Per- and polyfluoroalkyl substances (PFAS), a class of man-made chemicals, possess unique properties that have rendered them indispensable in various industries and consumer goods. However, their extensive use and persistence in the environment have raised concerns about their potential repercussions on human health and the ecosystem. This review provides insights into the sources, occurrence, transformation, impacts, fate, monitoring, and remediation strategies for PFAS.

Removal of chlorimuron-ethyl from the environment: The significance of microbial degradation and its molecular mechanism.

Chlorimuron-ethyl is a selective pre- and post-emergence herbicide, which is widely used to control broad-leaved weeds in soybean fields. However, herbicide residues have also increased as a result of the pervasive use of chlorimuron-ethyl, which has become a significant environmental concern. Consequently, the removal of chlorimuron-ethyl residues from the environment has garnered significant attention in recent decades.
