Outline of Final Research Achievements	This study deals with the cultivation of Jew's‐ear mushroom using two food industrial wastes in the Amami islands, fermented bagasse and brown sugar shochu lees, as culture media. These materials were found to be better for the mushroom cultivation than the conventional media. The medium containing 85% bagasse and 10% brown sugar shochu lees was the most effective for the cultivation. Due to the strong ability of mushroom to absorb potassium, 41.8% of potassium was removed from the starting media. The results suggest that the potassium amount in the agricultural fields will be reduced. As chemical analysis of the waste media showed the lower content of lignin, ADF and NDF, ration digestibility of the waste media from the fermented bagasse and the brown sugar shochu lees was deduced to be higher than the conventional waste media. It was also found that by applying carbon dioxide generated during mushrooms cultivation to passion fruits, sugar content in the fruits increased.
