Etymology
: the specific epithet
pseudoamylolytica
refers to the similar colony morphology to that of
Genolevuria amylolytica
.
Culture characteristics
: In YM broth, after 7 d at 17 °C, cells are ellipsoidal and subglobosal, 2.9– 5.2 × 3.3– 7.7 μm and single, budding is polar (
Fig. 7F
), a sediment is formed. After 1 mo at 17 °C, a ring and sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is cream, mucoid, smooth and glistening. The margin is entire. In Dalmau plate culture on corn meal agar, pseudohyphae are not formed. Sexual structures are not observed on YM, PDA, V8 and CM agar. Ballistoconidia are not produced.
Physiological and biochemical characteristics
: Glucose fermentation is absent. Glucose, galactose, L-sorbose, sucrose, maltose, cellobiose, trehalose, lactose, melibiose, raffinose, melezitose, inulin (weak), soluble starch, D-xylose (weak), Larabinose, D-arabinose, D-ribose, L-rhamnose (weak), Dglucosamine, N-Acetyl-D-glucosamine, D-mannitol (weak), Dglucitol (weak), Methyl-α- D-glucoside and salicin are assimilated as sole carbon sources. Methanol, ethanol, glycerol, erythritol, ribitol, galactitol, DL-lactate, succinate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, potassium nitrate, sodium nitrite, L-lysine, ethylamine hydrochloride and cadaverine dihydrochloride are assimilated as sole nitrogen sources. Maximum growth temperature is 28 °C. Growth in vitamin-free medium is negative. Starch-like substances are not produced. Growth on 50 % (w/w) glucose-yeast extract agar is negative. Urease activity is positive. Diazonium Blue B reaction is positive.
Physiologically,
G. pseudoamylolytica
differs from the two closely related species,
G. amylolytica
and
G. tibetensis
, in its inability to assimilate ribitol and succinate and the ability to assimilate L-sorbose and potassium nitrate (
Table S1.2
).
