After 3 days at 25 C on YPG agar, colonies are shiny, cream with a smooth texture. The colour turns to light orange (salmon colour) after 7 days of incubation. The colony has a small elevation and an entire margin. Cells are ovoid to ellipsoidal (2-.2.5x3.5–5.0 μm), occur singly or in pairs, and proliferate by polar budding. Blastoconidia and conidiogenous cells are observed on cornmeal agar. Pseudoyphae are produced on cornmeal agar. Fermentation is absent. The following compounds are assimilated: DNasr glucose, sucrose, raffinose, maltose, melezitose, cellobiose, Larabinose, D-mannitol, succinate and citrate. No growth occurs on galactose, melibiose, lactose, trehalose, soluble starch, salicin, L-rhamnose, D-xylose, D-arabinose, D-ribose, methanol, ethanol, glycerol, ribitol, myo-inositol, DL-lactate, arbutin or n-hexadecane. The following nitrogen compounds are assimilated: potassium nitrate, sodium nitrite, D-glucosamine, L-lysine and cadaverine. Ethylamine, creatine, creatinine and imidazol are not utilised. Vitamins are not required for growth. Urease reaction is positive (delayed). The diazonium blue B reaction is positive. Growth occurs at 30 C but not at 34, 37 and 40 C. No growth occurs on media supplemented with 0.01 and 0.1% cycloheximide, and 1% acetic acid. Growth occurs on 3 and 5% (w/v) sodium chloride with 5% (w/v) glucose. No growth occurs on 10% (w/v) sodium chloride with 5% (w/v) glucose. Growth occurs on 50% (w/w) glucose but not at 60% (w/w) glucose. Starch-like compounds are not produced. Acid production is negative.
