느타리버섯 균사 배양에 배지의 최적 혼합비를 구하기 위해 주재료인 면실피, 톱밥, 볏짚과 부재료인 제올라이트, 옥수수강, 탈지강, 백솜, 이분, 왕겨, 피이트를 사용하였다. 주재료인 면실피 톱밥 : 볏짚의 최적 혼합비는 6: 3: 1 (V/V, %)이었으며 각각 부재료의 최적 혼합비는 제올라이트 1%, 옥수수강 3%, 탈지강 5%, 백솜 1%, 이분 1%, 왕겨 7%의 순으로 균사생장과 밀도가 양호하였다. 주재료에 부재료 두 종류씩 혼합하였을때 최적 혼합비는 제올라이트:옥수수강의 경우 2:2(V/V, %), 탈지강과 백솜의 경우 3:2(V/V, %), 이분과 왕겨의 경우 1:3(V/V, %)이었다. 이를 다시 주재료와 부재료 모두를 함께 혼합할 경우 면실피 :톱밥 : 볏짚 : 제올라이트 : 옥수수강 : 탈지강 : 백솜 : 이분 : 왕겨 : 피이트를 43.0 : 17.2 : 25.8 : 2.0 : 2.0 : 3.0 : 2.0 : 1.0 : 3.0 1.0(V/V, %)로 혼합하였을 때 균사생장과 밀도가 모두 양호하였다.

The purpose of this study was to investigate the optimal mixture ratio for the mycelial culture of the Pleurotus ostreatus. The chief cultural media in this study were cotton hull, sawdust and rice straw and the supplemental media were zeolite, corn cob, defatted rice bran, white cotton, tobacco trash powder, rice hull and peat. The results of this study were as follows; the optimal mixture ratio of the chief cultural media were effective in 6 : 3 : 1(V/V, %), and the mycelial growth and density in the supplemental media were considerably better 1% zeolite,3% corn cob, 5% defatted rice bran, 1% white cotton, 1% tobacco trash powder, 7% rice hull in good order. The optimal mixture ratio be to the mixed supplemental media in the chief cultural media were as follows ; 2 : 2(V/V, %) at the conditions of mixed zeolite and corn cob; 3 : 2(V/V, %) at the conditions of mixed defatted rice bran and white cotton; 1 : 3(V/V, %) at the conditions of mixed tobacco trash powder and rice hull. At the conditions of the whole cultural media mixed, the mycelial growth and density were in good conditions ; cotton hull, sawdust, rice straw, zeolite, corn cob, defatted rice bran, white cotton, tobacco trash powder, rice hull, and peat were mixed 43.0 : 17.2 : 25.8 : 2.0 : 2.0 : 3.0 : 2.0 : 1.0 : 3.0 : 1.0 (V/V, %).
