Tetragonal crystalline MnO nanoparticles alleviate Pb stress in wheat by modulating antioxidant enzymes in leaves.

Agriculture ecosystems are seriously threatened by lead (Pb) contamination, which impacts plant growth and productivity. In this study, green synthesized manganese oxide nanoparticles (MnO NPs) using citrus peel were used for priming of wheat seeds. For the synthesis of MnO nanoparticles, peel extract of and 1 mM solution of manganese acetate were stirred and calcinated at 500 °C.

Heavy Metal (Arsenic) Induced Antibiotic Resistance among Extended-Spectrum β-Lactamase (ESBL) Producing Bacteria of Nosocomial Origin.

Antimicrobial resistance (AMR) is a leading cause of treatment failure for many infectious diseases worldwide. Improper overdosing and the misuse of antibiotics contributes significantly to the emergence of drug-resistant bacteria. The co-contamination of heavy metals and antibiotic compounds existing in the environment might also be involved in the spread of AMR.

Mycosynthesized Fe O nanoparticles diminish brown rot of apple whilst maintaining composition and pertinent organoleptic properties.

Aims: Iron oxide nanoparticles (Fe O NPs) were mycosynthesized using Trichoderma harzianum and applied to control brown rot of apple. The influence of Fe O NPs on the quality of fruit was also studied.

Methods And Results: Diseased apple fruits with brown rot symptoms were collected, and the disease-causing pathogen was isolated and identified as Fusarium oxysporum.
