Aspergillus terreus-Mediated Selenium Nanoparticles and Their Antimicrobial and Photocatalytic Activities

Selenium (Se) is a nutritional component necessary for animal and plant development reproduction. nanoparticles (SeNPs) have high absorption rate during routine supplementation. In the current study, cell-free extract of Aspergillus terreus was used as reducing stabilizing agent in synthesis SeNPs using green eco-friendly method. The mycosynthesized were characterized by UV-visible spectrophotometry, Fourier transform infrared spectroscopy, X-ray diffraction dynamic light scattering, transmission electron microscopy, scanning microscopy. results characterization process showed that had spherical shapes sizes less than 100 nm. Results exhibited promising antibacterial activity against both Gram-positive Gram-negative bacteria where inhibition zones 14, 20, 16, 13 mm toward S. haemolyticus, aureus, E. coli, K. pneumoniae, respectively. However, it weak antifungal C. albicans, zone 12 mm. efficacy decolorization malachite dye investigated. illustrated rapid biodegradation dye, reaching up to 89% after 240 min. conclusion, successfully biosynthesized A. demonstrated antimicrobial photocatalytic activities.
