|
This study was carried out to investigated optimum mixing ratio of Korean natural Acer tegmentosum for production of functional oyster mushroom. Total nitrogen and carbon sources of Acer tegmentosum were 0.2% and 44.4%, respectively and C/N ratio was 234. Total nitrogen source and pH of substrate mixed with Acer tegmentosum were 2.7~2.9 and 4.8~5.0, respectively. The contents of P2O5, K2O and MgO at Acer tegmentosum media were higher than that of the control. Mycerial growth was the fastest at Acer tegmentosum 10%, and slower by increase of Acer tegmentosum substrate. Yields of fruiting body was the highest to 159 g/850 mL at 10% of Acer tegmentosum and dimeter and thick of pileus were the highest, too. The L value of pileus and stipes were decreased by increase of Acer tegmentosum substrate, but there was no significant difference in the a-value and the b-value. The contents of P2O5 and K2O of fruiting body were increased at Acer tegmentosum substrate, but there was no significant difference in contents of CaO, MgO and Na2O.
