표고버섯균의 균사생육에 적합한 배지로는 PDA 배지, MYA 배지로 조사되었으며 배양환경 조사로 균사생육에 적합한 온도는 $25^{\circ}C$ 를 나타났다. 영양원 선발 결과 탄소원은 2%의 농도에서 Malt extract를 사용하였을 때 균사생장 및 밀도가 높게 나타났다. 질소원은 0.2%의 농도에서 Yeast extract를 사용하였을 때 균사생장 및 밀도가 높게 나타났다. 표고버섯(산조701호)의 수종별 추출액 배지를 이용한 결과, 신갈나무, 굴참나무, 상수리나무, 밤나무에서는 PDA(대조구)와 같이 생장이 우수하였다. 배양기간에 따른 버섯 생산성을 조사 해본 결과, 배양 110일에서 120일에서 우수한 수확량을 보였다. 재배수종에 따른 생산성은 굴참나무에서 가장 좋은 결과를 보였다. 【Lentinula edodes is known by oak mushroom. It has been favored as delicious and nutritious food and the low-calorie food with a high nutritional value. It is also functional food since it contains a material well-known for its medicinal benefits. Since the growth and quality of oak mushrooms are sensitively affected by environmental conditions, an adequate environmental control is very essential to improve the yield and quality under protected cultivation. The main objectives of the study were to investigate cultural characteristics of mycelial growth and in vitro fruiting of Lentinula edodes. The optimum culture media for mycelial growth of L. edodes were PDA and MYA. Similarly, optimum temperature was $25^{\circ}C$ . Malt extract(2%) and yeast extract(0.2%) were optimum carbon and nitrogen sources. Optimal culture period was 110~120 days in sawdust medium. Mycelial growth in medium(61 mm/7 days) Quercus mongolica extract the most good. Among different five log types, highest mycelial growth and fruiting productivity were observed in Quercus variabilis sawdust(20.9%).】 |
