ABSTRACT The current spreading of nanomaterial applications supports the search for further possible functions theses diminutive particles. antibacterial potentiality zinc oxide (ZnO) nanoparticles (NPs), compared with conventional ZnO powder, against nine bacterial strains, mostly foodborne including pathogens, was evaluated using qualitative and quantitative assays. NP more efficient as agent than powder. Gram‐positive bacteria were generally sensitive to Gram negatives. exposure...

Brucellosis is regarded as one of the major zoonotic infections worldwide. It was first reported in Egypt 1939 and now endemic, predominate species Brucella cattle buffalo B. melitensis. The aim study to estimate seroprevalence spp. reared households an Egyptian village, identify risk factors for animals testing seropositive assess knowledge, attitudes practices (KAPs) livestock owners with regards brucellosis. A cross-sectional carried out a village Menufiya Governorate Egypt. In June July...

Bioactive nanocomposites were constructed, containing chitosan (Cht), extracted from shrimps’ wastes, and transformed into nanoparticles (NPs) using ionic-gelation. Selenium NPs (Se-NPs) phytosynthesized cinnamon (Cinnamomum zeylanicum) bark extract (CIE), characterized evaluated with Cht-NPs as antimicrobial composites against bacterial food-borne pathogens “Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Listeria monocytogenes” potential edible coating (EC) basements. The...

Abstract Selenium nanoparticles (SeNPs) are reinforced safe forms of the essential micronutrient selenium (Se) which take a lead in countless biotechnological and biomedical applications. The phycosynthesis SeNPs was successfully investigated using cell-free extract microalgae, Spirulina platensis. phycosynthesized S. platensis -SeNPs ( Sp SeNPs) were characterized several characterization techniques such as UV-Visible, transmission electron microscopy, Fourier transform infrared...

Citrus production and trading are seriously affected by fungal decays worldwide; the green mold infection Penicillium digitatum could be most disastrous. The substitutions of chemical synthetic fungicides with effectual natural alternatives global demands; plant extract from pomegranates peels (PPE), biosynthesized selenium nanoparticles PPE (PPE/SeNPs) chitosan (NCT) were suggested as efficacious fungicidal agents/nanocomposites to control P. strains.PPE Punica granatum was extracted...

Cancers still globally endanger millions of people yearly; the incidences/mortalities colorectal cancers are particularly increasing. The natural nanoparticles (NPs) and marine biopolymers were anticipated to provide effectual safe significances for managing cancers. transformation curcumin nano-curcumin (NCur) was conducted with gum Arabic. resulted NCur utilized biosynthesis selenium NPs (SeNPs), then bioactive nanocomposites (NC) from them fucoidan (Fu) fabricated evaluated as candidates...

Abstract BACKGROUND The ongoing postharvest loss in citrus fruits, due to fungal infection, is a chronic economic and agricultural problem. Most of damage caused by Penicillium spp., e.g. green mold ( P. digitatum ) blue italicum ). Fungal chitosan, from Mucor rouxii , plant extracts cress seeds, olive leaves, pomegranate peels senna pods, were evaluated as antifungal agents against the phytopathogenic fungi, using vitro qualitative quantitative assays. RESULTS All natural tested exhibited...

Fungal chitosan was extracted from Aspergillus niger mycelia. The produced characterized with deacetylation degree of 89.2%, a molecular weight 2.4 × 10 4 Da, and 96.0% solubility in 1% acetic acid solution. antibacterial activity fungal evaluated against two foodborne pathogens, that is, Salmonella typhimurium Staphylococcus aureus , using the established assays, for example, zone growth inhibition agar plat count tests, 2,3,5,-triphenyltetrazolium chloride (TTC) as chromogenic marker...

Abstract Botrytis cinerea Pers, the gray mold fungus, is among most dangerous plant pathogens that cause great losses in agricultural crops. The botryticidal activities of nanosized silver (nano Ag), fungal chitosan (CTS) irradiated (IrCTS), and nano Ag‐IrCTS composite were investigated. All examined materials exhibited powerful antifungal activity against B. . effective compound was with a minimal inhibitory concentration 125 μ g/mL. microscopic examination, treated composite, revealed an...

An eco-friendly process for the silver nanoparticles (Ag-NPs) biosynthesis was investigated using fungus Monascus purpureus as a safe and commercially used microorganism. M. growth filtrate reduction of aqueous nitrate into Ag-NPs with almost 100% size range 1-7 nm, which considered one smallest microbial biosynthesized Ag-NPs. The were structurally characterized UV, FTIR, DLS, TEM, XRD. stable after 3 months no alteration in shape or size. showed reductase activity, whereas its pigments...

Chitosan and its nanoparticles (NPs) could be extracted from numerous fungal species used as effectual carriers for bioactive compounds. The chitosan (FC) was innovatively acquired Fusarium oxysporum grown mycelia, characterized NP synthesis loading with bee venom (BV). nano-FC (NFC) had 192.4 nm mean diameter, 38.22% capacity, 92.42% entrapment efficiency. BV release NFC pH time dependent; burst detected at the first 6 h, followed by gradual releases up to 30 h. in vitro anticancer...
