Tatumella

RANK: Genus

TAXONOMY: cellular organisms -> Bacteria -> Proteobacteria -> Gammaproteobacteria -> Enterobacteriales -> Enterobacteriaceae -> Tatumella

OVERVIEW:

Small rod-shaped cells 0.6–0.8 × 0.9–3 μm, conforming to the general definition of the family Enterobacteriaceae. Contains the enterobacterial common antigen. Gram negative. Nonmotile at 36°C; over half the strains are motile by means of polar, subpolar, or lateral flagella when grown at 25°C. Facultatively anaerobic. Catalase positive (weak and slow). Oxidase negative. Nonpigmented. Stock cultures often die within a few weeks on laboratory media. Biochemically more active at 25°C than at 36°C. Ferment, rather than oxidize, d-glucose; without the formation of visible gas. Reduce nitrate to nitrite. Very inactive biochemically; positive tests only for Voges—Proskauer (Coblentz method), phenylalanine deaminase, and fermentation of sucrose, trehalose, and d-mannose. Negative for most tests: indole production, methyl red, Voges—Proskauer (O'Meara method), citrate utilization (Simmons), H2S production (TSI), urea hydrolysis, lysine decarboxylase, arginine dihydrolase, ornithine decarboxylase, growth in the presence of cyanide (KCN test), malonate utilization, esculin hydrolysis, ONPG, gelatin hydrolysis (22°C), lipase (corn oil), DNase, gas production during fermentation, and the fermentation of lactose, d-mannitol, dulcitol, adonitol, myo-inositol, d-sorbitol, l-arabinose, raffinose, l-rhamnose, maltose, d-xylose, cellobiose, α-methyl-d-glucoside, erythritol, d-arabitol, glycerol, and mucate. Have very large zones of inhibition around antibiotics; susceptible to colistin, nalidixic acid, sulfadiazine, gentamicin, streptomycin, kanamycin, tetracycline, chloramphenicol, carbenicillin, ampicillin, and cephalothin (disk diffusion method on Mueller–Hinton agar). Large zone of inhibition around a penicillin G (10 U) disk, in contrast to most other Enterobacteriaceae.

The mol% G + C of the DNA is: 53–54.
