Nutritional Physiology and improvement of substrate of Lentinus edodes

표고 버섯(Lentinus edodes)의 영양생리 및 기질개발

Researches were carried out to find the optimal conditions of carbon sources, nitrogen sources and pH for the maximum production of sporophore of Lentinus edodes. Dextrin, aspartic acid and pH 4.0 were the best conditions for yield of sporophore by using replacement culture technique. The production of sporophore was stimulated by addition of 0.8% triacylglycerol in NS medium. Coffee waste was chosen for the best substrate among the poplar, oak, white aspen saw dust and coffee waste. Increased growth of mycelim and yield of sporophore was obsewed by adding tannin up to 0.1% as substrate.

자실체 생장을 위한 액체 정치 배양에서 탄소원, 질소원, pH의 효과를 검출한 결과 dextrin, aspartic acid, pH 4.0에서 각각 가장높은 건물중을 보였으며, 0.8% triacylglycerol 첨가시 자실체 생장이 촉진되었다. 고체배지 사용시 포플라, 백양나무, 참나무 톱밥 그리고 coffee waste 중 coffee waste에서 가장높은 자실체 건물중을 얻었으며 0.1% tannic acid의 첨가시 자실체 및 균사체 생장에 좋은 결과를 얻었다.
