General information
Description and emendation
The cells are gram-negative rods which are 0.6-0.8 by 0.9-3.0 µm. Some filaments may be formed. Endospores have not been observed. One strain, strain H2S, is motile at 36°C (3 to 5 days), and 66% are weakly motile (3 to 7 days) at 25°C. Flagella are difficult to demonstrate, but they appear to be single polar, subpolar, and lateral and, rarely, bipolar. On blood agar at 24 h, colonies are 0.5 to 1.0 mm in diameter, low convex with entire edges, semitranslucent, smooth, and glossy. The colonies are not as large as those of most species of the Enterobacteriaceae, but T. ptyseos strains do grow on MacConkey, eosin methylene blue, Tergitol 7, and brilliant green agars. Growth occurs at 25 and 36°C, but not at 42°C. T. ptyseos strains ferment D-glucose, produce catalase, reduce nitrate to nitrite, and are positive for phenylalanine and Voges—Proskauer (Coblentz method). Oxidase, urease, indole, L-lysine decarboxylase, L-ornithine decarboxylase, and gelatin tests are negative. The L-arginine dihydrolase reaction is variable. Acid is produced from Dglucose, sucrose, trehalose, salicin, D-mannose and (usually) D-xylose, melibiose, and glycerol without gas formation. No acid is produced from D-mannitol, lactose, or maltose. Simmons citrate tests are usually positive at 25 but not 36°C. The G+C content of the T. ptyseos type strain is 54 mol%.
1: Gram-negative, non-capsulated, non-spore-forming small rods that are 0.6-1.2 × 0.9-3.0 µm in size. Cells are motile by means of polar, subpolar or lateral flagella or non-motile at 36°C. Facultatively anaerobic, fermentative, catalasepositive (weak and slow) and oxidase-negative. Nonpigmented, or pale beige to pale orange. Glucose dehydrogenase, gluconate dehydrogenase and 2-ketogluconate dehydrogenase are produced. Reduce nitrate to nitrite. Indole, urease and gelatin tests are negative. Positive for Voges-Proskauer (Coblentz method), methyl red and citrate (Simmons); phenylalanine, arginine dihydrolase and ONPG tests are variable. Negative for H2S (TSI), lysine decarboxylase, ornithine decarboxylase, tryptophan deaminase, KCN test, lipase and DNase. Acid is produced from L-arabinose, Dgalactose, D-glucose, glycerol, D-mannitol, D-mannose, melibiose, D-ribose, trehalose and D-xylose (variable reaction for T. morbirosei), but not from amygdalin, dulcitol, erythritol, glutarate, glycogen, histamine, myo-inositol, methyl α-Dglucoside, propionate, L-rhamnose, sorbitol or L-sorbose. NAcetyl-D-glucosamine, 4-aminobutyrate, L-asparagine, Laspartic acid, bromosuccinic acid, D-fructose, fumarate, bgalactopyranoside, D-gluconic acid, α-D-glucose 1-phosphate, α-D-glucose 6-phosphate, L-glutamic acid, glycerol, inosine, 5-ketogluconate, D-mannose, L-proline, D-psicose, D-ribose, succinic acid, trehalose, thymidine and uridine are utilized as sole sources of carbon and energy. Susceptible to many antibiotics. Isolated from human clinical samples, fruit and soil. The G+C content of the DNA ranges from 49.8 to 53 mol%.
