Abstract

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 $P_2O_5$, $K_2O$ 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 $P_2O_5$ and $K_2O$ of fruiting body were increased at Acer tegmentosum substrate, but there was no significant difference in contents of CaO, MgO and $Na_2O$.

국내에서 자생하는 산겨릅나무 톱밥의 적정 첨가량을 구명하여 기능성 느타리버섯 재배를 위한 자료로 활용하기 위하여 실험을 실시하였다. 산겨릅나무 톱밥의 수분함량은 5.8%였고, pH는 5.8이였다. 총질소함량은 0.19%였고, 총탄소함량은 44.4%였으며, C/N율은 234%였다. 혼합배지의 pH는 4.8~5.0이였으며, 총질소함량과 총탄소함량은 수확후배지에서 증가하였지만, C/N율은 오히려 감소하였다. 무기성분인 $P_2O_5$, $K_2O$, MgO 함량은 무처리보다 산겨릅나무 톱밥배지에서 높았지만 CaO, $Na_2O$ 함량은 오히려 감소하는 경향을 보였다. 균사생장량은 산겨릅나무 톱밥이 10% 첨가된 배지에서 가장 빨랐고, 첨가량이 증가할수록 균사생장 속도는 느렸다. 자실체 수량은 산겨릅나무 톱밥 10% 첨가시 10% 159 g/850 으로 가장 높았다. 갓의 직경과 두께는 산겨릅나무 톱밥의 비율이 10% 첨가시 가장 높았으며, 대의 굵기와 길이도 산겨릅나무 톱밥의 비율이 10% 첨가시 대조구보다 굵고 길었다. 대와 갓의 경도는 산겨릅나무 톱밥의 비율이 20% 첨가시 가장 높았다. 수확기 자실의 갓과 대의 L값은 532배지보다는 산겨릅나무 첨가배지에서 낮은 값을 나타냈지만 산겨릅나무 첨가량에 따라서는 큰 차이를 보이지 않았으며, a, b값은 처리간에 뚜렷한 차이가 없었다. 자실체의 $P_2O_5$, $K_2O$의 함량은 산겨릅나무 톱밥 첨가에서 증가하였지만, CaO, MgO, $Na_2O$ 함량은 거의 차이가 없었다. 자실체의 CU의 함량은 산겨릅나무 톱밥의 첨가량이 증가할수록 감소하였지만, Fe와 Mn 의 함량은 증가하였고, Zn 함량은 산겨릅나무 20% 첨가시 가장 높았다.
