Objectives: To evaluate the efficacy of edible mushroom, Macrocybe gigantea for the biosynthesis of silver nanoparticles, antioxidant property and antibacterial property. Methods: M. gigantea pure culture was isolated using tissue culture in a petri-plate comprising potato dextrose agar (PDA) medium, spawn was prepared using sorghum grains and mushrooms were grown indoors using paddy straw in an uniquely designed environment for mushroom growth. The green synthesis of silver nanoparticles with AgNO 3 , antioxidant activity and antibacterial potential against a few food-borne bacteria were all investigated. The formation of AgNPs was further confirmed using a UV-Visible spectrophotometer. The silver nanoparticles were examined using Fourier-transform infrared spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The disc diffusion method was used to test the bacteriostatic and bactericidal activity of synthesised silver nanoparticles against selected food-borne bacteria such as Escherichia coli, Bacillus subtilis and Streptococcus mutans. Findings: The existence of phytochemicals such as alkaloids, terpenoids, phenols, flavonoids, proteins, and carbohydrates was revealed. Furthermore, the AgNPs produced from M.gigantea demonstrated absorbance at 420nm in a UV-Visible spectrophotometer. According to the SEM pictures, AgNPs appear spherical with diameters ranging from 50 to 70nm. At 100g/mL, the DPPH antioxidant assay exhibited the maximum percentage of inhibition of 67.94%, with an IC50 value of 57.07g/mL. The produced AgNPs also inhibited bacterial growth significantly. Green synthesised AgNPs from M.gigantea were produced in an environmentally friendly, quick and simple technique that functions as an antibacterial agent against certain food-borne pathogens such as E. coli, Bacillus subtilis, and Streptococcus mutans. The antibacterial screening demonstrates the biocidal ability of AgNPs from M.gigantea, which could be employed in the food processing and packaging industries. Novelty: This study is regarded as the first attempt to synthesise AgNPs from M.gigantea for use against food-borne bacteria.

“…The genus is similar to another edible mushroom genus, Calocybe, both having conspicuous large basidiomata. But Macrocybe species differ from Calocybe in lacking siderophilous granulation in the basidia and in molecular characteristics (Devi and Sumbali 2021). Macrocybe gigantea is an edible species with many varieties recognized and is cultivated in wild tropical/ subtropical regions of the world.…”

“…According to previous studies, this species can easily and successfully be cultivated in wheat straw. Also, the study of Devi and Sumbali (2021) suggested the use of pearl millet (Cenchrus americanus) spawn for the quick and successful cultivation of M. gigantea. According to Kushwaha et al (2016), lentil straw is a promising substrate for the cultivation of M. gigantea.…”

The wild edible mushroom Macrocybe gigantea is widely consumed as one of the prime seasonal delicacies in the tropical and subtropical regions of the world. In this study, M. gigantea was identified through morphological and phylogenetic analyses. Spawn production and cultivation parameters of M. gigantea were investigated for the first time in Sri Lanka. The mycelial growth was observed in potato dextrose agar medium, while paddy grains were used for spawn production. A mixture containing rubber sawdust (100 kg), rice bran (18 kg), CaCO3 (2.5 kg), gypsum (1 kg), and MgSO4 (0.35 kg) was tested as a substrate for colonization bags. In addition, gene sequence-data, proximate analysis, energy value, and mineral elements of cultivated M. gigantea were studied. Mycelia in mushroom growth bags were cultivated under the temperature range of 27–30 ℃ and relative humidity of 60 %. Three weeks after inoculation, the primordia appeared and it ook four additional days until the occurrence of young fruit bodies. A second flush was harvested 3 weeks after the first. Proximate analysis, energy value and mineral element analysis were recorded as 85.3 % moisture, 0.8 % ash, 1.6 % fat, 2.3 % protein, 10.0 % carbohydrate, 0.28 % potassium (K), 0.00064 % iron (Fe), 0.0024 % sodium (Na), and energy 63.6 kcal/100g. This study provides valuable information concerning the cultivation and nutritional composition of M. gigantea in Sri Lanka.
