초록

본 연구에서는 국내 전통누룩에서 분리한 증류식 소주용 효모의 생리적 특성을 조사하고 동정하였다. 분리균(N4)의 26S rDNA-D1/D2 염기배열은 Saccharomyces cerevisiae 표준균주(NRRL Y-12632)와 100% 상동성을 나타내었고 다극출아에 의해서 증식하였다. Glucose, galactose, maltose, sucrose를 발효할 수 있으며 trehalose, raffinose, methylglucoside를 자화할 수 있었다. $40^{\circ}C$ 이상에서는 증식하지 못했으며 50% glucose와 10% NaCl 농도에서 성장할 수 있었다. 염기배열, 형태관찰 및 생리적 특성을 종합하여 분리균을 S. cerevisiae로 동정하였다.

The occurrence and characterization of yeast isolated from Korean traditional nuruk were investigated. Sequences of the D1/D2 domain of the 26S rDNA were identical for a strain examined and had a similarity value of 100% compared to sequences of the type strain of Saccharomyces cerevisiae (NRRL Y-12632). The isolate able to assimilate with trehalose, raffinose, and methyl-glucoside assimilate was also capable of glucose, galactose, maltose, and sucrose fermentation. It did not proliferate at $40^{\circ}C$ or above, but was able to grow in concentration of 50% glucose and 10% NaCl. By combining nucleotide sequence, morphological observation, and physiological characteristics, the isolate was identified as S. cerevisiae.
