Study on characteristic of mycelial culture in ear mushroom

ABSTRACT : This study was performed to obtain the scientific data an artificial culture of ear mushroom( Auricularia auricula ). Liquid cultural of Auricularia auricula . mycelium was characterized with respect to temperature, pH, compositions of inorganic, carbon and nitrogen. The its optimum temperature and media pH were at 25℃ and pH 5.0 ~ 6.0 on the mycelial growth, respectively. The optimum inorganic compositions and concentration for mycelial growth were MgSO 4 0.05%(w/v) and KH 2 PO 4 0.1%(w/v), respectively. The optimum carbon sources and nitrogen sources were black-sugar 2%(w/v) and soybean powder at 0.3~0.5%(w/v) with7 days optimum culture time.KEYWORDS : Auricularia auricula., carbon sources, nitrogen sources * Corresponding author 서 론 목이는 세계적으로 널리 분포되어 있는 버섯으로 한국, 중국, 일본 등지에서 많이 발생되고 있는 버섯이다(Chen, Hou. 1979). 목이에 대한 분류 체계는 목이목(Auriculariales) 목이과(Auricu-lariaceae) 목이속( Auricularia )에 속하는 목이( Auricularia au-ricula )와 털목이버섯( Auricularia polytriha
