한국 전통주인 막걸리의 원료인 누룩에 대한 연구의 일환으로 각종 누룩 균주를 단독 접종하여 술담그기를 한 후 맛과 알코올 농도등을 기존의 방법으로 생산된 막걸리와 비교 연구하였다. 무작위로 선정된 4가지의 균의 성장과정을 무균 상태에서 다양한 수분 첨가조건으로 조사하였으며, 전분 분해능도 관찰하였다. 균사의 성장과정에서 이산화탄소 생산과 무게 손실을 측정하였으며, 그 결과는 균종에 따라서 다르게 나타났다. Abisida와 Rhizopus 균에서는 함량이 적은 곳에서 잘 자라는 반면 Aspergillus와 Mucor는 비교적 수분함량이 많은 자랐다. 첨가량이 적을수록 전통 누룩에서 발견된 균들이 본 연구에서는 고두밥을 이용해 술을 담그는 전통적인 방법에 의한 경우와 균을 이용하여 경우 술의 성분과 맛을 서로 비교하였다. 결과, 우리의 전통주는 접합균을 이용한 누룩으로 만들어지고, 대표적인 균들은 Absidia, Mucor 및 Rhizopus로 생각되었고, 누룩은 효소원이라기...
