General information
Description and emendation
Cells are Gram-stain-negative, motile rods. Colonies are non-pigmented and transparent. Growth is facultatively anaerobic, chemoheterotrophic. Catalase activity is positive and oxidase activity is negative. D-Glucose is fermented, and lysine decarboxylase is present. Urea is hydrolysed, acetoin is produced, nitrate is reduced to nitrite, H2S and indole are not produced, gelatin is not hydrolysed, citrate is not utilized, and β-galactosidase, ornithine decarboxylase, arginine dihydrolase and tryptophan deaminase activities are absent. The genus-specific signature region in the 16S rRNA gene is 5'-AGGAGGAAGGGTGAGCAGTGAATAGCTGTTTGC (the position of the 5' nucleotide in the 16S rRNA gene sequence of Escherichia coli is 444). The major cellular fatty acids (>10%) are C16:0, C17:0 cyclo, C18:1 ω7c, summed feature 2 (C14:0 3-OH and/or iso-C16:1 I) and summed feature 3 (C16:1 ω7c and/or iso-C15:0 2-OH).
