패랭이꽃으로부터 분리한 효모 Starmerella vaccinii 균주 특성

초록

Two hundred and fifty-eight strains of yeast were isolated from wild flowers collected in Chuncheon, Gangwon Province, Korea. The MBY/L7303 strain from Dianthus chinensis showed remarkable growth in medium supplemented with glucose, xylose, cellobiose, and galactose as the carbon source. This strain was identified as Stamerellera vaccinii, and its 26S rRNA gene sequence was registered in GenBank (MW465704). The S. vaccinii MBY/L7303 utilized glucose, cellobiose, sucrose, galactose, xylose, xylan, and starch as carbon sources and did not produce ethanol. The strain grew to a maximum cell density (OD600) of 21.93 ± 0.09 in the cellobiosesupplemented medium. The highest specific growth rate was 0.41 ± 0.00 1/h at pH 5.0 and 30°C. These results serve as valuable information for the potential industrial application of S. vaccinii.
