Etymology
: the specific epithet
maotaiensis
refers to the geographic origin of the type strain, Maotai county, Guizhou.
Culture characteristics
: In YM broth, after 7 d at 17 °C, cells are ovoid and ellipsoidal, 3.6– 5.2 × 4.5– 6.2 μm and single, budding is polar (
Fig. 8G
), a sediment is formed. After 1 mo at 17 °C, a ring and a sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is orange, butyrous, smooth and glossy. 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 are subglobosal to ellipsoidal, 2.4– 3.5 × 3.5 –5.3 μm (
Fig. 8H
).
Physiological and biochemical characteristics
: Glucose fermentation is absent. Glucose, galactose, sucrose, maltose, cellobiose, trehalose, melibiose, raffinose, melezitose, inulin, soluble starch (delayed and weak), D-xylose, L-arabinose, D-arabinose, L-rhamnose, succinate (delayed and weak) and citrate (delayed and weak) are assimilated as sole carbon sources. L-sorbose, lactose, D-ribose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, ethanol, glycerol, erythritol, ribitol, galactitol, Dmannitol, D-glucitol, Methyl-α- D-glucoside, salicin, DL-lactate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate and ethylamine hydrochloride are assimilated as sole nitrogen sources. Potassium nitrate, sodium nitrite, L-lysine and cadaverine dihydrochloride are not assimilated. Maximum growth temperature is 28 °C. Growth in vitamin-free medium is positive. Starch-like substances are produced. Growth on 50 % (w/w) glucose-yeast extract agar is negative. Urease activity is positive. Diazonium Blue B reaction is positive.
Physiologically,
Di. maotaiensis
and the closely related species
Di. ovata
,
Di. kandeliae
,
Di. zsoltii
,
Di. catarinoi
,
Di. takashimae
and
Di. athyrii
can be distinguished from one another.
Di. maotaiensis
and
Di. ovata
differ from the other five species in their ability to grow in vitamin-free medium (
Table S1.9
).
