Nutritional analysis of cultivated Pleurotus giganteus in agricultural waste as possible alternative substrates

Pleurotus giganteus is a wild edible mushroom that was successfully domesticated in Thailand. In this research, a P. giganteus strain (MFLUCC23–0016) was isolated into PDA agar medium with the best growing spawn detected in millet and sawdust at 11.10 ± 0.34 mm/day, 9.02 ± 0.40 mm/day respectively. Fruiting bodies occurred 14 days after unsealing the substrate bag, which produced large basidiomata and obtained a higher total yield of fresh weight from the sawdust and sawdust + corn cob substrate at 180.77 ± 44.41 g, 176.60 ± 17.65 g, respectively, compared to sawdust + rice straw and sawdust + sugarcane bagasse (35.30 ± 14.15 g, 34.52 ± 11.29 g, respectively) in 60 days with developed fruiting bodies in a 7-day cycle. Three soil casing formulas could be used for the casing of the soil for the P. giganteus fruiting trial, in which T1 obtained a higher total fresh weight at 278.54 ± 89.04 g followed by T2 at 218.35 ± 92.53 g and T3 obtained the lowest yield at 137.28 ± 67.42 g. Nutritional analysis of 100 g of dried P. giganteus showed 61.32 ± 0.0% of carbohydrates content, 20.318 ± 0.8 (g/100 g) of protein content, 15.6 ± 0.5% of moisture content, 14.28 ± 0.3% of fiber content, 5.61 ± 0.9% of ash content, and 2.98 ± 1.58 (g/100 g) of fat content.
