The process of producing straw mushrooms (Volvariella volvacea)

Abstract

The invention relates to a process for producing straw mushrooms (Volvariella volvacea) using straw as a substrate. The process includes the following steps: preparing dry straw with a moisture content of no more than 20% and free from mold; treating the straw by soaking it in lime water with a pH of 13 to 14, supplemented with antagonistic microorganisms and hydrolytic enzymes; incubating the substrate twice at temperatures of 55-60°C and 60-70°C respectively; creating a three-layered substrate bed; inoculating straw mushroom spawn on a granular or cotton substrate; controlling the moisture content of the mushroom mycelium using a sensor system combined with automatic misting; stimulating fruiting body formation using LED lights; and harvesting and treating the growing medium with saturated steam combined with regenerating microorganisms. The process described in the invention allows for synchronized control of raw materials, moisture content, fruiting body formation, and post-harvest substrate treatment, thereby increasing productivity, reducing the risk of wild fungal infections, shortening substrate isolation time, and limiting the use of harmful chemicals.
