Isolation of Protoplast from Aerial Mycelia and Fruit-Body Formation from Regenerated Mycelia in Pleurotus cornucopiae

抄録

We have developed a simple and efficient method for protoplast isolation from Pleurotus cornucopiae. Protoplasts were isolated from aerial mycelia cultured on potato dextrose agar medium without time-consuming propagation in liquid culture. Protoplast yield was significantly increased by means of a decompressing pretreatment of mycelia in enzyme solution and a subsequent enzyme reaction with vibrational mixing. The isolated protoplasts regenerated mycelia and these mycelia formed fruit-bodies without any morphological abnormalities.
