摘要

PROBLEM TO BE SOLVED: To provide a medium for mushroom culture, a method for culturing mushroom and a nutrient additive for mushroom culture capable of facilitating handling of fossil seashell and increasing a fruit body yield and calcium content in a fruit body. SOLUTION: This medium for mushroom culture is obtained by forming fossil seashell powder into a granular state of 1-5 mm diameter and adding 0.3-3% based on medium weight of the fossil seashell powder to a medium. Otherwise the fossil seashell powder is formulated with a water-soluble polysaccharide or a lignin in the weight ratio of 8 to 9.5:2 to 0.5 and 0.3-3% based on medium weight of the mixture is added to a medium to give the objective medium for mushroom culture.
