Bimetallic selenium/zinc oxide nanoparticles: biological activity and plant biostimulant properties.

Extracts of medicinal seeds can be used to synthesize nanoparticles (NPs) in more environmentally friendly ways than physical or chemical ways. For the first time, aqueous extract from unexploited grape seeds was used in this study to create Se/ZnO NPS utilizing a green technique, and their antimicrobial activity, cytotoxicity, antioxidant activities, and plant bio stimulant properties of the economic Vicia faba L. plant were evaluated.

Functional analysis of bacterial genes accidentally packaged in rhizospheric phageome of the wild plant species .

The study aimed to reveal the structure and function of phageome existing in soil rhizobiome of in order to detect accidentally-packaged bacterial genes that encode Carbohydrate-Active enZymes (or CAZymes) and those that confer antibiotic resistance (e.g., antibiotic resistance genes or ARGs).

Moderate Seasonal Dynamics Indicate an Important Role for Lysogeny in the Red Sea.

Viruses are the most abundant microorganisms in marine environments and viral infections can be either lytic (virulent) or lysogenic (temperate phage) within the host cell. The aim of this study was to quantify viral dynamics (abundance and infection) in the coastal Red Sea, a narrow oligotrophic basin with high surface water temperatures (22-32 °C degrees), high salinity (37.5-41) and continuous high insolation, thus making it a stable and relatively unexplored environment.

Low Host Abundance and High Temperature Determine Switching from Lytic to Lysogenic Cycles in Planktonic Microbial Communities in a Tropical Sea (Red Sea).

The lytic and lysogenic life cycles of marine phages are influenced by environmental conditions such as solar radiation, temperature, and host abundance. Temperature can regulate phage infection, but its role is difficult to discern in oligotrophic waters where there is typically low host abundance and high temperatures. Here, we study the temporal variability of viral dynamics and the occurrence of lysogeny using mitomycin C in a eutrophic coastal lagoon in the oligotrophic Red Sea, which showed strong seasonality in terms of temperature (22.
