Abstract In the present study, zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles (NPs) were produced by the eco-friendly green synthesis method using the aqueous extract of Ganoderma adspersum . ZnO and MgO NPs were characterized using XRD and SEM, which are among the most well-known structural and morphological characterization methods. Besides, the photocatalytic and antibacterial activities of NPs produced were investigated in detail. XRD measurements confirmed that both nanoparticles were produced as intended. Furthermore, it was determined that the ZnO NPs were in the form of nanonails with a homogeneous distribution, while the MgO NPs appeared to be arranged in a specific order and had an irregular planar morphology by means of SEM measurements. As for the photocatalytic performances of green synthesized ZnO and MgO NPs, it was found out that both NPs had high photocatalytic activity. As for the photocatalytic results, ZnO and MgO NPs produced with G. adspersum scavenged approximately 98.7% at 140 min and 91.6% at 200 min. Furthermore, it was determined that the synthesized both NPs exhibited significant antibacterial impacts in terms of inhibition zone against six different microorganisms ( A. baumannii ATCC BA1609, E. coli ATCC BAA-2523, E. faecalis ATCC 49452, P. aeruginosa NCTC 12924, S. aureus NCTC 10788, Y. enterocolitica ATCC 27729). Antimicrobial activity investigation showed that ZnO and MgO NPs green synthesized by G. adspersum revealed the highest antimicrobial activity against P. aeruginosa NCTC 12924 with the inhibition zone value of 12.0 and 10.0 mm, respectively).
