Sustainable biosynthesis of metal oxide nanoparticles using an eco-friendly approach is a growing research area owing to their promising environmental and biomedical applications. This work aims biosynthesize characterize magnesium (MgONPS@Aj) for possible application in dye biosorption antibacterial activity. For the first time, MgONPS@Aj was successfully synthesized by harnessing exometabolites Aspergillus japonicus. Various parameters were statistically optimized maximize production Plackett Burman's design central composite design. The analysis variance (ANOVA) revealed that pH most significant variable, affecting bioproduction process followed biomass quantity Mg2+ precursor concentration. suggested model (quadratic) greatly acceptable due nonsignificant lack fit (15.10), P-value (0.001). characterized X-ray powder diffraction, Fourier-transform infrared (FTIR) spectroscopy, transmission electron microscope (TEM), Scanning microscopy. A high capacity (204.08 mg/g) reactive black 5 achieved within 40 min mg biosorbent dose (MgONPS@Aj), 100 mg/l initial concentration, 6.0. pseudo-second-order (R2 0.9842) Langmuir isotherm 0.9422) models with dimensionless separation factor (RL) 8 × 104, hinting favorable effective molecules. 81.97 mg/g after five successive cycles hints nanomaterial suitable several time utilization. Biogenic displayed dramatic concentration-dependent activity largest inhibition zones P. aeruginosa (24.1 ± 0.8 mm, MIC: 3.125 µg/ml), E. coli (22.3 0.7 MIC 6.25), B. subtilis (14.7 0.4 12.5 µg/ml) S. aureus (19.2 0.6 6.25 µg/ml). further interpreted molecular simulation analysis. lowest binding affinity determined between target bacterial proteins (chloramphenicol acetyltransferase coli, MurE). ligand can bind active site's residues (Tyr172 SER224), indicating mechanism. study recommends as eco-friendly, reusable alternative traditional anionic sorbents uniquely candidate antimicrobial
