Description of Mrakia terrae YP 416

Cells are oval shaped and budding is polar ( Fig. 1 ). Colonies are convex, smooth, and orange-colored after 3 days of incubation on YM agar at 10℃. In the API 20C AUX test, strain YP416 is positive for glucose, inulin, sucrose, raffinose, melibiose, galactose, lactose, trehalose, maltose, melezitose, methyl-D- glucoside, cellobiose, salicin, L- sorbose, D- xylose, L- arabinose, D- ribose, methanol, ethanol, ribitol, xylitol, galactitol, D- mannitol, D- glucitol, D- lactate, succinate, citrate, D- gluconate, gluconolactone, D- glucosamine, N - acetyl-D- glucosamine, potassium nitrate, sodium nitrate, cadaverine dihydrochloride, and L- lysine; and negative for soluble starch, cellobiose, salicin, L- sorbose, L- rhamnose, D- xylose, L- arabinose, D- arabinose, D- ribose, methanol, ethanol, glycerol, erythritol, ribitol, xylitol, galactitol, D- mannitol, D- glucitol, and myo-Inositol.

Strain YP 416 ( KCTC 27889 ) was isolated from the soil collected in Pocheon City , Gyeonggi Province, Republic of Korea .
