“…This change is a piece of clear evidence for the synthesis of AuNPs from the mushroom due to the behavior of these NPs in the absorption of the UV-Visible [25]. This agrees with the results of Owaid et al [11], who mycosynthesized AuNPs from the oyster mushroom Pleurotus cornucopiae.…”

“…This experiment showed that time was an affirmative act to increase the intensity of the purple color. This increase is evidence that the rise in the heating leads to an increase in the activation energy [12] and allowed to active substances of the extract to play an essential role as a reducing agent for gold ions in the form of atoms, as mentioned by Owaid et al [11]. Figure 2A showed the absorption band at 1,394 cm -1 .…”

“…Ghassan Adnan NAEEM et al http://wjst.wu.ac.th Figure 3 represents the specific EDX analysis of the residue resulting from the interaction of the fungus extract with the gold salt. This indicates the presence of the gold component, which comes from AuNPs [11]. Generally, Figure 3 also shows the presence of carbon, nitrogen and oxygen, due to the various organic compounds such as amino acids, fatty acids, and polyphenols present in the Coprinus comatus extract [18,30].…”

“…These nanoparticles also were applied in the decolorization of dyes [7]. The mycosynthesized AuNPs from mushrooms were succeeded by using few edible mushrooms, including Pleurotus sapidus [8], Pleurotus florida [5,9], Pleurotus ostreatus [7,10], Pleurotus cornucopiae [11], Lentinula edodes [12], and Flammulina velutipes [13].…”

The present research aims to produce gold nanoparticles (AuNPs) from the aqueous extract of locally isolated mushroom Coprinus comatus from Hit city, Iraq. Its properties were studied using the optical vision, UV-Vis, EDX, XRD, FTIR, AFM, and Zetasizer analyses. The exposure of the colloidal solution of AuNPs to UV radiation was investigated for 1, 2, and 3 h. The results showed the color change of the interaction mixture from light yellow to purple after 25 min. The lambda max of the absorbance reached 530 nm using UV-Visible spectrum as evident in the formation of AuNPs. FTIR spectra revealed the presence of functional groups related to peptides, proteins, flavonoids, monosaccharides, and phenolic compounds, which reduced gold ions. The EDX technique showed that the formed nanoparticles were AuNPs. XRD results showed that AuNPs have a face-centered cubic (fcc) crystal. The UV irradiation at different times led to an increase in the intensity of absorbance and sizes of AuNPs from 17.39 nm before the irradiation and switched to 58.16, 59.13, and 47.35 nm after 1, 2, and 3 h, respectively, but their sizes remained within the nanoscale range (less than 100 nm). In conclusion, the best result was observed after about an hour on the effects of UV irradiation on sizes of AuNPs, which reached smaller nanoparticles compared with times 2 and 3 h.

Mycosynthesis of AuNPs by Trichoderma hamatum would provide some useful data for oriented biosynthesis of AuNPs. In addition, the applications of mycosynthesized AuNPs were studied against some pathogenic bacteria. Therefore, the gained results detect that these antimicrobial nanoparticles could be explored as hopeful candidates for a variety of biomedical and pharmaceutical applications. This study should provide a further prudence for the fungal-mediated synthesis of AuNPs.
