Abstract

본 발명은 발효산물의 연속적 제조 방법, 보다 구체적으로는 발효에 의해 알콜을 비롯한 균주 대사산물을 제조하는데 있어서, 발효시에 응집성 균주 및 유동식 필터를 사용함으로써 발효산물을 높은 세포농도로 경제적 및 연속적으로 제조하는 방법에 관한 것이다.
본 발명에 따르면, 목적 발효산물, 특히 알콜의 발효에 의한 생산성이 이론치에 가까운 수율로서 반응기 체적 1리터당 1시간동안 70그람 이상(종래 방식의 70배 이상)에 달할 뿐만 아니라 발효산물의 균주 세포 농도도 반응기 1리터당 130그람 이상으로 유지되며, 발효 반응기를 수개월 이상 동안 연속 운전할 수가 있다는 잇점이 있다. 따라서, 본 발명에 의하면 원료 가격에 있어서 전체 생산원가 기준으로 30% 이상 절약할 수 있고, 시설비, 공장부지 비용, 인건비, 동력비, 폐수처리비용 등에 있어서 많은 생산 원가 절감을 할 수 있다.
