Abstract

The effect of the addition of various vegetable oils on the mycelial growth was studied. Most vegetable oils were proved to be stimulative for the mycelial growth, and the best mycelial growth (12 mg/ml) was obtained with the addition of cotton seed oil. Several agricultural wastes i.e., rice straw, peanut hull, sawdust, rice hull, cocoa hull, coffee waste and beer waste were empolyed as substrates for sporophore production of p. sajor-caju. The biological efficiency(BE) for sporophore productions of rice straw and peanut hull were 36.4% and 32.6%, respectively. The highest yield of sporophore was obtained from the mixture of rice straw (50%) and beer waste (50%)(BE 109.6%) followed by peanut hull (50%) and beer waste (50%)(BE; 74.5%).

P.sajor-caju의 균사체 생장에 oil 첨가효과를 검토한 결과 대부분의 식물성 oil 에서 좋은 결과를 보였으며, 그 중 cotton seed oil을 배지 100ml에 2.5ml 첨가하였을 때 균체량이 무첨가구에 비하여 약 4배정도 이었다. 자실체 생산 기질로 농산 및 산업폐기물인 볏짚, 땅콩박, 왕겨, 톱밥 ,코코아박, 맥주박, 커피박 등을 사용한 결과 볏짚의 biological efficiency(B.E.)가 36.4%였으며 땅콩박은 32.6%로 나타났다. 또한 볏짚(50%)과 맥주박(50%)을 혼합하였을 경우 B.E가 109.6%로 최고치를 나타냈으며 땅콩박(50%)과 맥주박(50%)을 혼합하였을 경우에도 B.E.가 74.5%로 높은 수확량을 나타내었다.
