Tropism Chemoorganotrophic
Oxygen Grow in the presence and absence of oxygen respiratory and fermentative metabolism

Requirements  
Products  
Enzymes Catalase-positive except for Shigella dysenteriae 0 group 1 and Xenorhabdus nematophilus; oxidase negative.
Unique features . Grow well on peptone, meat extract, and usually MacConkey's media. Some grow on D-glucose as the sole source of carbon, others require vitamins and/or amino acids.;. Not halophilic. Acid and often visible gas is produced during fermentation of D-glucose, other carbohydrates and polyhydroxyl alcohols. Nitrate reduced to nitrite except by some strains of Erwinia and Yersinia.

Genome Family Enterobacteriaceae
G+C Mol % 38-60 (Tm, Bd).
  DNAs from species within most genera are at least 20% related to one another and to Escherichia coli, the type species of the family. Notable exceptions are species of Yersinia, Proteus, Providencia, Hafnia and Edwardsiella, whose DNAs are 10-20% related to those of species from other genera. Except for Erwinia chrysanthemi (Le Minor et al. 1972) all species tested contain the enterobacterial common antigen (Kunin 1963; Kunin et al 1962; Whang and Neter 1962; Vosti et al 1964; Le Minor et al 1972).
