Cultural Practices to Enhance Mushroom (Pleurotus eryngii) Yield & Concentration of the Antioxidants Selenium & Ergothioneine

摘要

A summary of our work on enhancing mushroom yield and concentration of the antioxidants selenium and ergothioneine in the King Oyster -mushroom is presented here. Improved yield was achieved by supplementation of substrate with a commercial delayed-release nutrient and the use of a casing layer. Yield was increased by 141 percent from cased substrates vs. non-cased substrates and yield was further enhanced by the addition of delayed-release supplement at time of casing (179 percent total increase). Mushrooms were darker in color and lower in solids content when produced on cased substrates compared to non-cased substrates.
