Abstract:
This study investigates the use of Bacillus subtilis-synthesized chitosan nanoparticles (CNPs) for textile wastewater treatment and antimicrobial applications. Bacillus subtilis was isolated and used to produce CNPs, confirmed by UV-Vis spectroscopy with peaks at 325.6 nm. The textile effluent, with high pH and turbidity, showed significant improvements in physicochemical properties after CNP treatment, with the highest decolourization (63.0%) observed at 3 mL CNPs. The nanoparticles also exhibited dose-dependent antibacterial activity against Escherichia coli and Staphylococcus aureus, with larger inhibition zones for S. aureus (17 mm) compared to E. coli (15 mm). These results highlight the potential of Bacillus subtilis-synthesized CNPs as an effective and sustainable solution for both wastewater treatment and microbial control.
