Abstract

We investigated the effect of different media components on the characteristics and productivity of Lentinula edodes cultivated in sawdust. Ten substrates were used for this study. Soybean and cotton seed meal were unsuitable substrates as fungal mycelia did not grow to maturity during the incubation period. Lentinula edodes (NIFoS culture number 2462) was grown on the ten substrates, and soybean hull, mixed medium, cotton seed hull and corn grain showed greater effect on the productivity than wheat bran. However, wheat bran induced higher productivity in NIFoS 2778 than the other substrates. Sawdust medium with soybean meal produced smaller fruiting bodies than the other substrates. In contrast, corn meal media produced larger mushrooms than the other substrates. The external characteristics of the mushrooms varied based on the substrates upon which they were grown. This is not surprising given that the substrates differed with respect to carbohydrate and protein content, e.g., cotton seed and soybean meal contained a higher crude protein and crude ash than the other substrates tested.

본 연구에서는 표고 톱밥재배의 배지 조성에 따른 생산성 및 버섯 특성에 대해 알아보기위해 총 10가지의 농업부산물을 영양원으로 사용하였다. 대두박과 면실박을 이용한 배지에서는 배양기간 동안 균사가 완전히 생장하지 않아서 재배에 이용할 수 없었다. NIFoS 2462 균주에서는 대두피, 면실피, 파옥쇄, 혼합배지에서는 밀기울보다 높은 생산량을 나타내었으며, NIFoS 2778에서는 밀기울의 생산량이 다른 영양원들보다 높게 나타났다. 대두피를 사용한 배지에서 발생한 버섯들은 다른 배지에서 발생된 버섯들보다 작은 크기의 버섯이 생산되었으며, 반대로 옥분을 이용한 배지에서는 다른 영양원을 사용한 배지보다 큰 버섯이 생산되었다. 이를 통해 배지에 첨가되는 영양원이 버섯의 특성에 영향을 주는 것으로 확인되었다. 영양원들의 기초 성분 조사 결과, 대두박과 면실박은 조단백질과 조회분의 비중이 높았다. 그리고 면실박에서는 총유기물 함량과 가용성무질소물의 양이 다른 영양원들에 비해 낮게 나타났다. 이러한 영양원들의 기초성분이 버섯 재배시 생산량 및 버섯의 특성에 영향을 준다고 여겨지며, 이와 같은 표고 재배에 대한 연구를 통하여 다양한 자원에 대한 활용 가능성을 넓히는 것이 중요하다.
