Abstract

The contents of raw materials which are components of mixed substrate for mushroom cultivation were analyzed to optimize the composition. The pure protein(amino acid) level of soybean meal was the highest, 44.02% followed by those of soybean curd residue(31.5%) and cotton seeds meal(30.6%). The non protein nitrogen(NPN) contents in crude protein of main nitrogen materials were 2.4% for soybean meal and 5.6% for dried soybean curd residue, while those of wheat bran and rice bran used as the carbon source were relatively higher, 17.6% compared to that of nitrogen supplying media. Crude protein content per price was 6.0 for rapeseed meal, indicating that it is high crude protein content per price. Nitrogen-free extract(NFE) considering as an ingredient for mycelial growth were high in alphacorn(72.9%) and wheat bran B(57.2%). Acid detergent fiber(ADF) was high in corncob, 51.88%, its use for cultivation of brown rot fungi including Lentinus lepideus should pay attention because the fungi lack complete lignin degradation activity.

버섯의 혼합배지에 사용되는 배지원료의 아미노산과 일반성분을 분석한 결과, 순단백질(아미노산) 함량은 대두박이 44.02%로 가장 높았고, 건비지가 31.5, 면실박이 30.6%로 나타났다. 주요 질소원 배지지료의 비단백태질소화합물(NPN)의 조단백질에 대한 비율은 대두박이 2.4%, 건비지는 5.6%였지만, 탄소원 배지재료인 미강과 밀기울은 17.6%로써 높았다. 조단백질/가격(원)은 채종박이 6.0으로 가격대비 조단백질량이 높은 것을 알 수 있었다. 균사생장에 관여하는 가용성무질소물(NFE)는 알파콘이 72.9%, 소맥피B가 57.2%로 높았다. 산성세제불용섬유(ADF)는 콘콥이 51.88%로 높았는데, 잣버섯 등 갈색부후균이 이용하기 어려운 리그닌이 포함되어 있으므로 사용에 주의가 필요하다.
