Antibacterial Activity of Intracellular Greenly Fabricated Selenium Nanoparticle of Lactobacillus pentosus ADET MW861694 against Selected Food Pathogens

This study aimed at intracellular biosynthesis of selenium nanoparticles using Lactobacillus pentosusADEB (LP) and the greenly fabricated were characterized based on visual observation, spectroscopy, microscopy, energy dispersive X-rays, X-ray Diffraction, dynamic light scattering properties. The antibacterial activities (LP-SeNPs) against selected foodborne pathogens evaluated. A gradual change in colour from brown to reddish indicates formation Nano-selenium. highest absorption peak for LP-SeNPs was visible between 200-300nm. FTIR analysis shows major peaks around 1635.40, 1587.31 2163.00, 2936.70, 2968.50, 3254.38 cm-1 indicate presence amides nanoparticle surface. SEM TEM extrusion spherical shape SeNPS pentosus cell membrane which synthesis nanoparticles. crystalline with an average diameter 106.1 nm a polydispersity index 0.295. Elemental 1.37 Kev present culture had antagonistic pathogens. have activity all test Salmonella arizonae (11.3 mm). In conclusion, broad-spectrum food-borne addition food can be added advantage controlling
