Antibacterial Activity of a New Strain of MSQ21 against .

<b>Background and Objective:</b> Actinobacteria represent the most prominent group of microorganisms, which produce a vast number of bioactive compounds especially antibiotics. The present study investigated the antibacterial activity of some actinomycete isolates against <i>Ralstonia solanacearum</i> type 3 biovar 2 (phytopathogenic bacterium that causes tomato wilt disease and brown rot of potatoes). <b>Materials and Methods:</b> The most potent actinomycete isolates in the antibacterial activity was further identified up to species based on its phenotypic and molecular characteristics.

Nanostructure Engineering via Intramolecular Construction of Carbon Nitride as Efficient Photocatalyst for CO Reduction.

Light-driven heterogeneous photocatalysis has gained great significance for generating solar fuel; the challenging charge separation process and sluggish surface catalytic reactions significantly restrict the progress of solar energy conversion using a semiconductor photocatalyst. Herein, we propose a novel and feasible strategy to incorporate dihydroxy benzene (DHB) as a conjugated monomer within the framework of urea containing CN (CNU-DHBx) to tune the electronic conductivity and charge separation due to the aromaticity of the benzene ring, which acts as an electron-donating species. Systematic characterizations such as SPV, PL, XPS, DRS, and TRPL demonstrated that the incorporation of the DHB monomer greatly enhanced the photocatalytic CO reduction of CN due to the enhanced charge separation and modulation of the ionic mobility.

Benzoic Acid and Its Hydroxylated Derivatives Suppress Early Blight of Tomato () via the Induction of Salicylic Acid Biosynthesis and Enzymatic and Nonenzymatic Antioxidant Defense Machinery.

Tomato early blight, caused by , is a destructive foliar fungal disease. Herein, the potential defensive roles of benzoic acid (BA) and two of its hydroxylated derivatives, -hydroxybenzoic acid (HBA), and protocatechuic acid (PCA) against were investigated. All tested compounds showed strong dose-dependent fungistatic activity against and significantly reduced the disease development.

Efficiency of Red Onion Peel Extract Capsules on Obesity and Blood Sugar.

Background And Objective: Red onions are one of the most consumed vegetable crops in Egypt, their peel is rich in antioxidants that reduce the risk of diabetes and weight is lost. The study aimed to extract bioactive compounds present in Egyptian Red Onion Peels Waste (ROPE), increasing their efficiency and protecting them using nano-encapsulation as new emerging technology.

Materials And Methods: Extraction of the bioactive compounds in the Egyptian red onion peels was carried out to study their antioxidant activity before and after nano-emulsions and micro-capsules, their physical and morphological characteristics with their different nano-forms and their application in sponge cake products.
