Abstract	Waste mushroom medium (WM) was saccharized with cellulase to obtain glucose after shiitake fruiting bodies were harvested 3 and 5 times (WM-3 and WM-5, respectively). Glucose can be used as a feedstock for the production of bioethanol or other bioproducts. WM-3 and WM-5 were analyzed for the amounts of shiitake fruiting bodies harvested and chemical components. The fresh weight ratio of shiitake fruiting bodies from the 4th and 5th harvests relative to the total fresh weight of shiitake fruiting bodies until the 5th harvest was 4.1 %. The additional 2 harvests decreased WM dry weight to 78.0 % and slightly decreased acid-insoluble lignin and xylan contents from 11.9 and 12.0 % to 10.0 and 9.6 %, respectively. The additional 2 harvests did not decrease glucan content. WM-5 included 31.6 % of glucan relative to dry weight, and 54.5 % of the glucan was saccharized to glucose with Meicelase (5 FPU/g substrate) at 40 °C for 48 h without pretreatment. The saccharification ratio of WM-3 was 45.0 % under the same saccharification condition. The amounts of saccharized glucose in WM-3 and WM-5 were 155.1 ± 9.8 mg/g substrate and 191.3 ± 9.2 mg/g substrate, respectively.
