Description of Rhodotorula alborubescens B2UV-201

Cells are oval shaped and budding is polar ( Fig. 1 ). Colonies are convex, smooth, and pink colored after 3 days of incubation on YPD agar at 10℃. In the API 20C AUX test, strain B2UV-201 is positive for glucose, adonitol, xylitol, D-maltose, D-saccharose (sucrose), D-melezitose, and D-raffinose; weak positive for L-arabinose, D-xylose, D-galactose, D-sorbitol, D-cellobiose, and D-trehalose; but negative for N -acetyl-glucosamine, D-lactose (bovine origin), glycerol, calcium 2-keto-gluconate, inositol, and methyl-α-D-glucopyranoside.

Strain B2UV-201 ( KCTC 37245 ) was isolated from soil collected in Nowon , Seoul, Republic of Korea .
