RESULTS AND DISCUSSION
A strain of yeast designated NP01 was isolated from the
Thai traditional alcoholic beverage ou. NP01 yeast was
found to be the fermentation yeast with globose or
subglobose cells. Pseudohyphae were not observed
during cultivation. D-Glucose, D-galactose, maltose, and
sucrose were fermented, while lactose and trehalose
were not. According to these and other characteristics, the
isolated yeast was identified as a strain of the genus S.
