“…Previous FTIR analyses on metallic NPs synthesized with other Ganoderma spp. confirm the presence of capping biomolecules that stabilize and affect the morphology of the nanostructures [ 36 , 37 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ]. Strong bands in the region of 3650–1000 cm −1 were reported for AgNPs synthesized using G. lucidum [ 45 ], with the –OH and C–OH stretching vibrations of polysaccharides represented by the appearance of a strong absorption band at 1043 cm −1 .…”

“…In the case of FTIR analysis for AgNPs synthesized using G. sessile , no previous studies report the production of metallic NPs or the analysis of the metabolites produced by this fungus. Recently, G. sessile was reported as a fast polysaccharide producer, achieving the highest biomass and polysaccharide yields, both in liquid culture and solid-state fermentation, compared with Ganoderma lingzhi and Ganoderma oregonense [ 40 ]. Thus, this fungus has high potential for the manufacture of dietary supplements [ 40 ] and for its use in the production of metallic NPs.…”

Silver nanoparticles (AgNPs) represent an excellent option to solve microbial resistance problems to traditionally used antibiotics. In this work, we report optimized protocols for the production of AgNPs using extracts and supernatants of Trichoderma harzianum and Ganoderma sessile. AgNPs were characterized using UV-Vis spectroscopy and transmission electron microscopy, and the hydrodynamic diameter and Z potential were also determined. The obtained AgNPs were slightly larger using the fungal extract, and in all cases, a quasi-spherical shape was obtained. The mean sizes of AgNPs were 9.6 and 19.1 nm for T. harzianum and 5.4 and 8.9 nm for G. sessile using supernatant and extract, respectively. The AgNPs were evaluated to determine their in vitro antibacterial effect against Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The minimum inhibitory concentration (MIC) was determined, and in all cases the AgNPs showed an antimicrobial effect, with a MIC varying from 1.26–5.0 µg/mL, depending on the bacterial strain and type of nanoparticle used. Cytotoxicity analyses of AgNPs were carried out using macrophages and fibroblast cell lines. It was determined that the cell viability of fibroblasts exposed for 24 h to different concentrations of AgNPs was more than 50%, even at concentrations of up to 20 µg/mL of silver. However, macrophages were more susceptible to exposure at higher concentrations of AgNPs as their viability decreased at concentrations of 10 µg/mL. The results presented here demonstrate that small AgNPs are obtained using either supernatants or extracts of both fungal strains. A remarkable result is that very low concentrations of AgNPs were necessary for bacterial inhibition. Furthermore, AgNPs were stable for more than a year, preserving their antibacterial properties. Therefore, the reported optimized protocol using fungal supernatants or extracts may be used as a fast method for synthesizing small AgNPs with high potential to use in the clinic.

Advancements in mycelium technology, stemming from fungal electronics and the development of living mycelium composites and skins, have opened new avenues in the fusion of biological and artificial systems. This paper explores an experimental endeavour that successfully incorporates living, self-regenerating, and reactive Ganoderma sessile mycelium into a model cyborg figurine, creating a bio-cybernetic entity. The mycelium, cultivated using established techniques, was homogeneously grown on the cyborg model’s surface, demonstrating robust reactivity to various stimuli such as light exposure and touch. This innovative merger points towards the future of sustainable biomaterials and the potential integration of these materials into new and existing technologies.

“…In China, many Ganoderma fungi are called a common name ‘Lingzhi’ in Chinese. A literature survey found that mounting documents discussed the importance of various species of Ganoderma mushrooms in the food field [1–6] . In fact, the annual production value for Ganoderma ‐derived healthcare products in China market is more than 7.5 billion US dollars.…”

Zizhines V, W, Y, Z, (�)-zizhines X, and Z1À Z3, and (�)-ganosinensol L, thirteen new compounds including four pairs of enantiomers and a known compound (À )-ganosinensol L, were isolated from the fruiting bodies of Ganoderma sinensis. Their structures were identified by spectroscopic, computational methods, and CD (circular dichroism spectroscopy) comparisons. Zizhines VÀ Z and Z1À Z3 are meroterpenoids consisting of the phenolic and the terpenoidal parts. All the compounds except zizhine Z3 bear a common trans-p-hydroxycinnamoyl group. Biological evaluation shows that (À )-zizhine Z1 inhibits cell migration in the MDA-MB-231 cell lines. The present study discloses the chemical profiling of G. sinensis and paves the way for its development as functional products to benefit chronic disorders.
