Summary: Seaweeds can serve as organic biostimulants for terrestrial plants. In this study, seaweed liquid organic biostimulants derived from Turbinaria ornata, Sargassum wightii and Halimeda opuntia were used to investigate their effects on the growth and biochemical profile of Vigna radiata. The findings showed that a 20% seaweed liquid organic biostimulant from H. opuntia had the highest impact on the growth and compositional changes of V. radiata. H. opuntia fertilizer also led to higher fatty acid contents in V. radiata. Additionally, T. ornata and S. wightii plants contained high levels of saponins and terpenoids. The study suggests that seaweed liquid organic biostimulants have potential environmental advantages over chemical fertilizers, and their use could have a positive impact on agricultural production.

Summary: Fish is a good source of protein and essential minerals and vitamins, but several food-borne disease outbreaks have been linked to fish consumption. This study evaluated gamma radiation as a method to preserve fish and reduce microbial contamination. The results showed that gamma irradiation effectively reduced aerobic plate count and pathogenic bacteria in fish samples, while having no significant effect on fish quality. Gamma irradiation is proposed as a cheap and safe method for reducing microbial contamination in fish.

Summary: This study evaluated the multidrug resistance and multivirulence profiles of Staphylococcus aureus strains isolated from cows with mastitis. All isolates were found to be biofilm-producing methicillin-resistant S. aureus (MRSA) strains. The tested essential oils (EOs) demonstrated antimicrobial and antibiofilm activities that matched with the phenotypic evaluation and molecular docking studies. Synergistic interactions between the investigated EOs and methicillin or vancomycin were detected. Additionally, 13 isolates showed a change in antimicrobial resistance patterns to sensitive phenotypes after treatment with any of the investigated EOs. Combining the EOs with available antimicrobial drugs can prevent treatment failure of bovine mastitis caused by resistant S. aureus.
