Description of Komagataeibacter melaceti SPV-2

(= KACC 22058)

Cells are Gram-stain-negative, non-flagellated, non-pigmented, and rod or coccus shaped (1.0-1.5 μm × 1.4-3.0 μm) after three days incubation on YPM medium at 28℃. Colonies are round, raised and brownish beige colored with a diameter less than 0.1 mm. Catalase-positive and oxidase-negative. Positive for aesculin hydrolysis; but negative for nitrate reduction, indole production, glucose fermentation, arginine dihydrolase, urease and gelatin hydrolysis. According to API 20 NE test results, it assimilates D- glucose; but does not assimilate L- arabinose, D- mannose, D- mannitol, 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 L- arabinose, D- ribose, D- xylose, D- galactose, D- glucose, D- mannose, D- melibiose, D- saccharose, D- trehalose, D- raffinose, gentiobiose, D- fucose and potassium 5-ketogluconate; but not produced from glycerol, erythritol, D- arabinose, 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, inulin, D- melezitose, amidon, glycogen, xylitol, D- turanose, D- lyxose, D- tagatose, L- fucose, D- arabitol, L- arabitol, potassium gluconate and potassium 2-ketogluconate. Strain SPV-2 (= KACC 22058) was isolated from potato vinegar sampled from Haenam-gun, Jeollanam-do. The GenBank accession number for the 16S rRNA gene sequence of strain SPV-2 is ON746600.
