Description of Mrakia frigida CY-9-10C

Cells are oval shaped, and budding is polar ( Fig. 1 ). Colonies are convex, smooth, and cream colored after 3 days of incubation on YPD agar at 10°C. In the API 20C AUX test, strain CY-9-10C is positive for N -acetyl-D- glucosamine, glucose, D- saccharose (sucrose), and D- cellobiose; weak positive for L- arabinose, D- lactose (bovine origin), D- trehalose, 2-keto-D- gluconate, D- galactose, and D- xylose; but negative for D- melezitose D- raffinose, glycerol, L- arabinose, adonitol, inositol, D- sorbitol, N -methyl-D- glucoside, D- glucose, and D- maltose.

Strain CY-9-10C was isolated from the soil collected in Cheongyang County, Republic of Korea.
