Abstract
Sansung takju, the Korean traditional liquor at a local area of Sansung in Pusan, has been widely drunken due to its tradition in this area. The studies on microorganisms of kokja, fermentation process and shelf-life of takju were carried out. The most abundant microorganism identified from a commercial Sansung kokja was Aspergillus, Mucor, Rhizopus and Penicillium were also identified. In case of a home-made Sansung kokja, Mucor was the most abundant one. Aspergillus, Rhizopus and Absidia were also identified in it. Saccharomyces, Micrococcus and Bacillus were identified in both kokja's but acid production bacteria were not found. Ethanol fermentation was carried out at
산성막걸리 곡자에 대한 미생물 분리와 발효과정 그리고 제성비율에 따른 저장성에 대해 조사하였다. 산성곡자의 미생물을 분리해 본 바, 시중에서 구입한 곡자의 경우 Aspergillus속 곰팡이가 가장 많이 존재하였고 Mucor속, Rhizopus속, Penicillium이 검출되었다. 그러나 산성지방에서 직접 구한 곡자의 경우 Mucor속이 가장 많이 존재하였으며 Aspergillus속, Rhizopus속, Absidia속이 검출되었다. 그외 Saccharomyces속의 효모와 Micrococcus속, Bacillus속의 세균이 검출되었으며 산생산균은 검출되지 않았다. 시장에서 구입한 곡자와 산성지방에서 직접 구한 곡자를 사용하여
