Cryptococcus adeliensis is a species of Cryptococcus that when plated on agar produces colonies that are cream colored, with a smooth, glossy appearance. The colonies frequently appear to have a soft texture. The optimal growth range for this species is at 25 degrees Celsius. Cryptococcus adeliensis is incapable of fermentation, as is typical of the Cryptococcus species. This species is able to use sucrose, maltose, cellbiose, trehalose, raffinose, citrate, inositolethanol, soluble starch, melezitose, xylitol, saccharate, salicin as well as many other compounds as sole carbon sources. Cryptococcus adeliensis is able to use nitrate, nitrite and cadaverine, a protein created when animals decay which produces the putrid smell associated with said decay, as sources of Nitrogen. This species forms starch as it grows. Cryptococcus adeliensis also grows on 0.01% cycloheximide.
