ABSTRACT

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 oC 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.
