Description of Gluconobacter thailandicus FR 36C4

(= KACC 22057)

Cells are Gram-stain-negative, flagellated, non-pigmented and rod shaped (0.9-1.1 μm× 1.5-2.4 μm) after three days incubation on YPM medium at 28℃. Colonies are round, raised and brownish beige colored with a diameter of 1.0 mm. Catalase-positive and oxidase-negative. Positive for glucose fermentation and aesculin hydrolysis; but negative for nitrate reduction, indole production, arginine dihydrolase, urease and gelatin hydrolysis. According to API 20 NE test results, it assimilates D- glucose and D- mannitol; but does not assimilate L- arabinose, D- mannose, N -acetylglucosamine, D- maltose, potassium gluconate, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid. According to API 50 CH test results, acid is produced from glycerol, erythritol, D- arabinose, L- arabinose, D- ribose, D- xylose, D- galactose, D- glucose, D- mannose, D- melibiose, D- saccharose, gentiobiose, D- lyxose, D- fucose and potassium 5-ketogluconate; but not produced from L- xylose, D- adonitol, methyl- β - D- xylopyranoside, D- fructose, L- sorbose, L- rhamnose, dulcitol, inositol, D- mannitol, D- sorbitol, methyl- α -D- mannopyranoside, methyl- α -D- glucopyranoside, N -acetylglucosamine, amygdalin, arbutin, esculin ferric citrate, salicin, D- cellobiose, D- maltose, D- lactose, D- trehalose, inulin, D- melezitose, D- raffinose, amidon, glycogen, xylitol, D- turanose, D- tagatose, L- fucose, D- arabitol, L- arabitol, potassium gluconate and potassium 2-ketogluconate. Strain FR36C4 (= KACC 22057) was isolated from fruit of Pseudocydonia sinensis sampled from Jeonju-si, Jeollabuk-do. The GenBank accession number for the 16S rRNA gene sequence of strain FR36C4 is ON746599.
