Article Description

This study is one such study where an eco-friendly approach has been followed in biosynthesizing TiO 2 NPs from Pleurotus ostreatus mushroom extract. Therefore, we object to biosynthesizing TiO 2 NPs and characterize them morphologically using UV, XRD, FTIR, FESEM, EDX, HR-TEM, AFM, and GCMS. The UV–visible spectroscopy absorption of synthesized TiO 2 NPs has peaked at 335 nm. The antibacterial activity was investigated by both isolated bacteria pathogens (gram-positive and gram-negative). The maximum growth inhibition zone was noted in S. mutans (14.3 ± 0.4), E. coli (14.1 ± 0.3), and S. epidermidis (13.3 ± 0.2). The in vitro cytotoxicity assay of TiO 2 NPs showed an IC 50 value of 47.42 µg/mL against MG-63 cancer cells. The photocatalytic degradation of methylene blue by TiO 2 NPs was investigated under UV–visible light irradiation. Due to the NPs tiny size and high dispersion, a rapid degradation (between 30 and 180 min) of almost 84.24% was accomplished. Even after the photocatalyst was used three times, there was no discernible difference in the TiO 2 NPs photocatalytic activity. The synthesized TiO 2 NPs successfully destroyed the Methylene Blue (MB) dye in an aqueous solution, promising wastewater dye remediation. Therefore, our research shows for the first time that biosynthesis of TiO 2 NPs using P. ostreatus extract can be an excellent outcome for emerging multipurpose and organic products.
