Bannoa hahajimensis

Bannoa hahajimensis Hamam., Thanh & Nakase 2002, in Hamamoto, et al., International journal of systematic and evolutionary microbiology 52, 1023-1032 (2002)

Etymology: Bannoa hahajimensis (ha.ha.ji.men´sis. N.L. adj. hahajimensis referring to Haha-jima, one of the Japanese Ogasawara Islands in the Pacific Ocean, where the type strain was isolated).

Diagnosis: After growth in YM broth (Difco) for 3 days at 25 °C, cells are spherical to ovoid (5·0-7·0 ×8·0-12·0 µm), single or in pairs. A sediment and a hydrophobic pellicle are formed after 1 month. After growth on YM agar (Difco) at 25 °C for 3 days, the streak culture is orange. After 1 month, the streak culture is red-orange, smooth, shining, butyrous and soft and has an entire margin. No pseudomycelium develops on Dalmau plate cultures on corn meal agar after 10 days at 25 °C. Ballistoconidia are formed on corn meal agar and YM agar. They are ovoidal and ellipsoidal, 3·0-6·0×7·0-14·0 µm. True mycelium with clamp connections at septa is produced after cell conjugation (A1×A2, A2×A3 and A3×A1). Teliospores are not formed. Unicellular basidia arise laterally on a clamp, sometimes terminally. Germination of basidia occurs by the formation of hyphae. Does not ferment D-glucose. Assimilates D-glucose, galactose, L-sorbose, sucrose, maltose, cellobiose, trehalose, melibiose, raffinose, melezitose, soluble starch, D-xylose, L-arabinose, D-arabinose (variable), D-ribose (variable), L-rhamnose, ethanol (variable), glycerol, ribitol (variable), galactitol (variable), D-mannitol, D-glucitol, methyl α-D-glucoside (variable), salicin, glucono-????-lactone (variable), 2-ketogluconic acid, 5-ketogluconic acid, DL-lactic acid (variable), succinic acid, citric acid and d-glucuronic acid. Does not assimilate lactose, inulin, erythritol, inositol or d-galacturonic acid. Assimilates L-lysine. Does not assimilate nitrate, nitrite, ethylamine or cadaverine. Maximum growth temperature is 28±29 °C. Growth does not occur in vitamin-free medium. р-Aminobenzoic acid (variable) and thiamin are required for growth. Growth does not occur on 50% (w/w) glucose/yeast extract agar. No starch-like substrate is produced. Xylose is absent from whole-cell hydrolysates Urease and Diazonium blue B reactions are positive.
