Budvicia Bouvet et al. 1985
General information
Description and emendation
cells are gram-negative, nonsporeforming, non-encapsulated, straight rods with peritrichous flagella (when grown at 22°C). Members of the genus conform to the definition of the family Enterobacteriaceae. Facultatively anaerobic; glucose fermenters; nitrate reducers. Oxidase test negative. Small colonies are produced on nutrient agar. Growth occurs between 4 and 37°C, but not at 42°C. No growth occurs in KCN medium. H2S produced; urea hydrolyzed. Indole not produced. Tryptophan and phenylalanine not deaminated. Lysine, arginine, and ornithine not decarboxylated. Voges-Proskauer test negative. Acid not produced from maltose, D-mannose, glycerol, and trehalose. Esculin not hydrolyzed. Gluconate test negative. o-Nitrophenyl-β-D-galactopyranoside hydrolyzed. Extracellular enzymes (lipase, Tween esterase, amylase, deoxyribonuclease, gelatinase [tube method]) not produced (in 6 days) or weakly produced (gelatinase [film method]). No growth on Simmons citrate or Trabulsi acetate. Growth factor requirements are complex. The enterobacterial common antigen is produced. The G+C content of the DNA is about 46 mol%.
1: May or may not grow at 37°C. May or may not produce hydrogen sulfide or acid from glycerol. May or may not hydrolyse urea or nitrophenyl-β-D-galactopyranoside. Motility may or may not be detected in liquid media, but is detectable in semisolid agar. The whole-cell fatty acid composition is dominated by C16:0, C16:1 ω7c, cyclo C17:0, C18:1 ω7c and C14:0.
