METHOD FOR REGENERATING MUSHROOM CULTURE MEDIUM WASTE VIA SOFT HYDROTHERMAL PROCESSING, AND NEW METHOD FOR UTILIZING BIOMASS

摘要

PROBLEM TO BE SOLVED: To provide a method for regenerating mushroom culture medium waste including: decomposing, extracting and eliminating harmful substance from mushroom culture medium waste; sterilizing the mushroom culture medium waste; inactivating mushroom growth-inhibiting substance; and appropriately drying the culture medium, so as to regenerate the mushroom culture medium waste as a new mushroom bed. SOLUTION: The method for regenerating mushroom culture medium waste which is a flow type, includes: subjecting the mushroom growth-inhibiting substance included in the waste culture medium to hydrolysis treatment in a liquid phase obtained by continuously feeding saturated steam to the mushroom culture medium waste so that the saturated steam comes in contact with the mushroom culture medium waste so as to be concentrated; further raising the temperature of the saturated steam fed by heating from outside to obtain dry steam whose steam saturation degree is reduced to 100% or less; extracting and eliminating the harmful substance and/or the mushroom growth-inhibiting substance in the mushroom culture medium waste by the dry steam; and further drying the mushroom culture medium waste.
