Novel insights into Bacillus thuringiensis: Beyond its role as a bioinsecticide.

This review explores the diverse applications of Bacillus thuringiensis (Bt) beyond its traditional role as a bioinsecticide. Bt produces a variety of compounds with distinct chemical structures and biological activities. These include antimicrobial agents effective against plant pathogens and bioactive compounds that promote plant growth through the production of siderophores, hormones, and enzymes.

Biodegradation effects of three species on iron-based oxides (Hematite - Goethite) in paint layer in oil paintings.

The inorganic colour layer based on iron oxide is affected by microorganisms (fungi) and leads to its deterioration due to feeding on the mineral elements through the chemical composition of the colour in the presence of a suitable environment (medium). Damage occurs as a result of heavy metal elements being removed from the colour, leading to a defect in the chemical composition and the fading of the colours. The current study showed the effect of the different types of the most common fungi on oil paintings ( and ) after cultivating the different types of fungi and obtaining pure colonies for each fungus separately and conducting a fungal infection on experimental samples with preparing the old techniques, coloured with hematite red and goethite yellow.

Review green synthesis of silver nanoparticles by using plant extracts and their antimicrobial activity.

Interest in the biosynthesis of nanoparticles has increased in the last era by researchers. Nanoparticles have several applications in different fields like optoelectronics, magnetic devices, drug delivery, and sensors. Nanoparticle synthesis by green methods is safe for the environment and should be explored and encouraged popularly since various plants' have the high extent to form these nanoparticles.

Larvicidal, pupalicidal and adulticidal effects of L. against dengue vector (Diptera: Culicidae) in Jazan region, K.S.A.

In the current study, the biological effects of various solvents concentrations of were assayed on different stages (larva, pupa and adult) of under controlled laboratory conditions. The life initiation and mortality for each insect stage were evaluated. Different lethal concentrations were measured.

Mechanical structures of sidewalk plants: Anatomical evaluation.

The mechanical structure of plant tissues has recently attracted a lot of attention. The present study aims to evaluate the importance of collenchymatous and sclerenchymatous tissues in supporting plant species in their harsh environments like road and street plant habitats. Dicots and monocots are classified into different models according to the types of supporting mechanisms.
