Gram-negative rods, 0.3-1.0 x 0.8-2.0 µm, occuring singly or in pairs. Motile by
peritrichous flagella.
peritrichous flagella.
Colonies on nutrient agar are light yellow, smooth, circular, entire and convex. Growth
occurs at 4-45 ºC, pH 4.0-9.0 and with 0-9 % NaCl (w/v), with optimal at 25-37 ºC, pH
7.0 and without NaCl. Facultatively anaerobic.

pyrolidonyl arylamidase, cystine arylamidase, naphthol-AS-BI-phosphohydrolase and valine arylamidase.
Negative results for methyl red test, phenylalanine, oxidase, and urease, acid production from potassium gluconate.
Variable results (E. mori strains are positive while E. tabaci are negative) for gelatin hydrolysis, and lysine decarboxylase.
Variable results (E. mori strains are negative while E. tabaci are positive) for H2S production and indole production.
