Description of Gluconacetobacter liquefaciens C23-3

(= KACC 22064)

Cells are Gram-stain-negative, non-flagellated, non-pigmented, and rod (0.9-1.0 μm × 1.6-2.3 μm) after three days incubation on YPM medium at 28℃. Colonies are round, raised and brownish beige colored with a diameter of 0.3 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 potassium gluconate; but does not assimilate L- arabinose, D- mannose, D- mannitol, N -acetylglucosamine, D- maltose, capric acid, adipic acid, malic acid, trisodium citrate and phenylacetic acid. According to API 50 CH test results, acid is produced from L- arabinose, D- ribose, D- xylose, D- galactose, D- glucose, D- fructose, D- mannose, D- melibiose, D- lyxose and D- fucose; but not produced from glycerol, erythritol, D- arabinose, L- xylose, D- adonitol, methyl- β - D- xylopyranoside, 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- saccharose, D- trehalose, inulin, D- melezitose, D- raffinose, amidon, glycogen, xylitol, gentiobiose, D- turanose, D- tagatose, L- fucose, D- arabitol, L- arabitol, potassium gluconate, potassium 2-ketogluconate and potassium 5-ketogluconate. Strain C23-3 (= KACC 22064) was isolated from fruit of Pyrus pyrifolia sampled from Naju-si, Jeollanam-do. The GenBank accession number for the 16S rRNA gene sequence of strain C23-3 is ON746603.
