Antifungal activity of volatile organic compounds from essential oils against the postharvest pathogens Botrytis cinerea, Monilinia fructicola, Monilinia fructigena, and Monilinia laxa.

Plant essential oils (EOs) were tested for their antifungal activity against gray mold and brown rot. Results showed that certain EOs inhibited the growth of the fungi, suggesting their potential use for controlling these diseases in fruit and vegetable storage.

The silver lining of antibiotic resistance: Bacterial-mediated reduction of tetracycline plant stress via antibiotrophy.

Scientists tested the effectiveness of a new bacterium, Erwinia strain S9, in helping pea plants tolerate tetracycline (TET) exposure. They found that supplementation with Erwinia strain S9 improved plant growth, reduced oxidative stress, and degraded TET. This could be a useful strategy for wastewater treatment or improving crop resistance in irrigation.

Efficient green silver nanoparticles-antibiotic combinations against antibiotic-resistant bacteria.

Researchers synthesized silver nanoparticles (AgNPs) with antibiotics and Mentha longifolia extract, comparing them to control AgNPs. Antibiotic-based AgNPs had altered properties and enhanced antibacterial activity, suggesting potential for combating antibiotic-resistant bacteria. (40 words)

Three Undescribed Iridoid derivatives Isolated from The Fruits of Vitex trifolia with Their Cytotoxic and Antimicrobial Activities.

Scientists isolated nine iridoid derivatives from the fruits of Vitex trifolia L., a medicinal plant in Vietnam. Four of the compounds showed significant antibacterial activity against various strains, while all nine compounds were not cytotoxic to lung cancer cells.
