Immunological Studies on Mutation Process and Substrate Induction of Trichoderma viride Cellulase

Trichoderma viride Cellulase의 돌연변이 과정 및 기질유도의 면역학적 연구

- Mutation process and substrate induction of 7i-ichoderma viride cellobiohydrolase were investigated by immunological techniques. Since mutants of Trichodemza uiride such as QM9123, QM9414, TKO41 and MCG77 produced immunologically same cellobiohydrolase, it may be that the mutation be occurred in the reguratory gene rather than in the structural gene of cellobiohydrolase. a-Cellulose and Solka Floc were found to be the best inducer for the production of cellobiohydrolase in Trichodemza viride culture compared to low molecular weight inducer such as carboxylmethyl cellulose and cellobiose.

Trichoderma viride의 변이주인 QM9123, QM9414, TK041 및 MCG77은 면역학적으로 동일한 cellobiohydrolase을 분비하는 결과로서 변이균주간은 구조 유전자는 동일하나 조절유전자가 변이했음을 알 수 있었고 탄소원의 cellobiohydrolase의 유도효과는 고분자 섬유소인 Alpha-cellulose와 Solk Floc의 가장 좋은 유도체였고, 저분자 유도체인 cellobiose와 CMC에 의해서 유도되는 형식이 다름을 알았다.
