In the precious report, the oxygen transfer in mycelial pellets of Lentinus edodes was studied and the distribysions of dissolved oxygen were recognized in the mycelial pellets.These results revealed that a decrease in the overall oxygen intake tare was induved.This paper deals with the distribution of respiratory activity in mycelial pellets as an extension of the precious studies above mintioned. In connection with the respiratory activiry, the phospate matabolic activity was also discussed.The age distribution in a giant colony of L. edodes on an agar medium was discovered to have a linear relation with the distance from the tip of the colony. A distinct correlation between the age of mycelia and their matabolic activity was found, i.e. the activities of phosphomonoesterase and respitation decreased with age, and the activity of ribonuclease increased. In mycelial pellets, also the same correlation was found between these three matabolic activities and age. On the other hand, there was no fixed correlation between the size of a pellet and its metabolic activities. Consequently, it is concluded that the culture age should be taken into consideration in the culture of shiigake.
