Abstract
본 발명에서는 목질섬유소를 당화하여 포도당과 자일로스 등의 단당류를 제조하기 위해 기존 공지의 강력한 효소 생산 미생물보다 여러가지 목질섬유소분해 효소활성이 더 증진된 목질섬유소분해효소를 생산하는 곰팡이 균주인 페니실리움 옥살리쿰 KL1이 제공되며, 이를 사용하여 저가의 천연 섬유질 원료로부터 경제적인 목질섬유소분해효소를 생산하는 방법이 제공되며, 목질섬유소로부터 포도당과 자일로스 등의 단당류를 생산하는 방법이 제공된다. 이 발명에 의해 목질섬유소 기질로부터 산업적으로 유용한 포도당과 자일로스 등의 단당류를 생산하는 데 필요한 효소비용을 크게 절감할 수 있다.
Description
제2도는 페니실리움 옥살리쿰 KL1 균사(hyphae)의 현미경적 형태이다.
제3도는 페니실리움 옥살리쿰 KL1 균주의 ITS 염기서열을 네이버 조이닝 법에 의하여 작성한 계통수를 나타낸 것이다.
제4도는 페니실리움 옥살리쿰 KL1 균주의 목질분해효소 비활성(specific activity)을 다른 회사 제품 효소들과 비교한 결과이다.
