DAD9926253C053429E16808DA935371E.taxon	description	Description. Culture characteristics: After 3 days of incubation in YM broth at 17 ° C, cells were ellipsoidal to ovoid, measuring 2.6 – 3.7 × 3.0 – 5.5 µm, and reproduced by monopolar budding (Fig. 4). After one month under the same conditions, conspicuous rings and sediment were present. On YM agar at 17 ° C for 3 days, colonies were creamy-white, butyrous, and emitted a characteristic aroma; the center was slightly raised and produced filaments when lifted with a loop. Pseudohyphae were not formed on cornmeal agar. No ascospores or sexual structures were observed on YM, PDA, V 8, or cornmeal agar after 6 weeks. Ballistoconidia were not produced. Physiological and biochemical characteristics: D-Glucose, sucrose, melibiose, raffinose, melezitose, inulin, soluble starch, L-rhamnose, ethanol, glycerol, galactitol, D-mannitol, D-glucitol, DL-lactic acid, and succinic acid were assimilated. D-Galactose, maltose, cellobiose, and citric acid were assimilated weakly or after a delay. L-Sorbose, trehalose, lactose, L-arabinose, D-arabinose, D-ribose, N-acetyl-D-glucosamine, methanol, erythritol, ribitol, α-methyl-D-glucoside, inositol, and hexadecane were not assimilated. Cadaverine dihydrochloride, L-lysine (weakly), and potassium nitrate (weakly) were utilized as sole nitrogen sources; ammonium sulfate, sodium nitrite, and ethylamine hydrochloride were not utilized. Starch-like compounds were not produced. Growth in vitamin-free medium was weak. No growth occurred on 50 % (w / w) glucose – yeast extract agar.	en	Tian, Lin, Phurbu, Dorji, Zheng, Yan-Yan (2025): Microbotryozyma lacustris sp. nov.

Culture characteristics: After 3 days of incubation in YM broth at 17 ° C, cells were ellipsoidal to ovoid, measuring 1.9 – 3.9 × 3.5 – 6.5 µm, and reproduced by monopolar budding (Fig. 3). After one month under the same conditions, prominent rings and sediment were present. On YM agar at 17 ° C for three days, colonies were creamy, smooth, glossy, and exhibited surface ridges with serrated margins. Pseudohyphae were not formed on cornmeal agar. No ascospores or sexual structures were observed on YM, PDA, V 8, or cornmeal agar after six weeks. Ballistoconidia were not produced. Physiological and biochemical characteristics: D-Glucose, sucrose, melibiose, D-arabinose, D-ribose, L-rhamnose, D-mannitol, and raffinose (delayed and weak) were assimilated. The following carbon sources were assimilated weakly or after a delay: D-galactose, sorbose, maltose, cellobiose, trehalose, lactose, melezitose, D-xylose, N-acetyl-D-glucosamine, ethanol, glycerol, galactitol, and hexadecane.
