Scytalidium thermophilum-colonized grain, corncobs and chopped wheat straw substrates for the production of Agaricus bisporus
We examined the possibility of cultivating Agaricus bisporus (Ab) on various grains and agricultural byproducts, with the objective of improving yield capacity of substrate pre-colonized by Scytalidium thermophilum (St). Radial growth rate (RGR) of St at 45 C ranged from no growth on sterile wheat grain to 14.9 mm/d on whole oats. The linear extension rate (LER) of Ab, grown on St-colonized substrate (4 days at 45 C), ranged from a low of 2.7 mm/d on 100% corncobs to 4.7 mm/d on a 50/50 mixture of ground corncobs/millet grain. Several other substrates containing wheat straw + ground corncobs + boiled millet and pre-colonized by St (4 days at 42 ± 3 C), were evaluated for production of Ab. The biological efficiency (BE) of production increased linearly with the addition of millet to the formula. However, substrates with millet levels P84% often were contaminated before mushroom harvest. Maximum BE (99%) and yield (21.6 kg/m2) were obtained on St-colonized wheat straw + 2% hydrated lime supplemented with 9% commercial supplement added both at spawning and at casing.
