Abstract

Neurospora crassa accumulated cadmium. iron, manganese and lead in the mycelium. The growth of N. crassa was inhibited in the presence of cadmium but not in the presence of iron or manganese. In the presence of lead. the growth of N. crassa was accelerated. In the presence of cadmium. mycelium became thick and a conidiospore grew into a mycelial ball instead of normal threadlike gro~1h. Each metal wa'i accumulated in different subcellular organelles bound to protein and induced different proteins.

Neurospora crassa 를 카드뮴, 철, 망간, 난 등이 각각 첨가된 배지에서 배양할 경우 각 중금속들이 균사에 저장되는 것을 관찰하였다. 각 중금속들은 단백질에 결합되더 각기 다른 세포네 소기관에 축적되었고, 중금속이 첩가된 배지에서 생장한 균사는 서로 매우 상이한 단백질 분포 양상을 보여 주었다. 가드뮴을 제외한 중금속들은 예상과는 달리 N. crassa 의 성장을 억제하지 않았으며, 납의 경우는 우히려 성장을 촉진하였다. 카드뮴이 첨가된 배지에서 condiospore 는 정상적인 길이 성장을 하지 못하고 둥근 형태로 생장하였으며, 길이 생장을 하던 균사는 두께가 두꺼워짐이 관찰되었다.
