초록

Flammulina velutipes(팽나무버섯)의 영양요구성에 대한 연구로써 각종 탄소원 및 질소원을 처리한 결과 mannitol과 glutamic acid 그리고 ammonium nitrate가 최대 균사체 생장을 보였으며, 최적 C : N ratio 로써 20 : 1이 선정되었다. Phosphate source로는 potassium dihydrogen phosphate가 좋은 결과를 나타내었으며, magnesium sulphate와 thiamin HCl이 균사체 생장을 촉진하였다. 이상의 결과로 최적 화학합성배지의 조성은 1.5% mannitol, 0.082% $NH_4NO_3$, 0.312% glutamic acid, 0.25% $KH_2PO_4$, 0.06% $MgSO_4{\cdot}7H_2O$ 그리고 $0.3\;{\mu}g/l$ thiamin HCl로 나타났다. 이와 같은 배지의 조성은 균사체 생장 뿐만 아니라 자실체 생장에도 효과가 있는 것으로 나타났다.

Abstract

Nutritional requirements for the growth of Flammulina velutipes were studied. Mannitol, glutamic acid and ammonium nitrate were chosen for the maximum mycelial growth when various carbon and nitrogen sources tested. Optimum C : N ratio for the mycelial growth was 20 : 1. Potassium dihydrogen phosphate was selected among the phosphate sources. Magnesium sulphate and thiamine HCl stimulate mycelial growth. Final compositions of optimized chemically defined medium were 1.5% mannitol, 0.082% $NH_4NO_3$, 0.312% glutamic acid, 0.25% $KH_2PO_4$, 0.06% $MgSO_4{\cdot}7H_2O\;and\;0.3\;{\mu}g/l$ thiamin HCl. This medium not only support mycelial growth but also induce fruit body formation.
