Chemoorganotrophic. The
majority of strains utilize citrate, acetate and malonate
as a sole carbon source after 3-4 days of incubation |

Nitrate is reduced to
nitrite. H2S is not produced in the butt of Kligler iron
agar.. Alginate is not utilized. Pectate is not
decomposed. Phenylalanine deaminate is not produced |
| Enzymes |
Oxidase-negative.
Catalase-positive Gelatinase, lipase, and
deoxyribonuclease are not produced Lysine and ornithine
decarboxylase tests are positive, but the arginine
dihydrolase test is negative Glucose is fermented with
the production of acid and gas. Acid is not produced from
D-sorbitol, raffinose, melibiose, D-adonitol and
myo-inositol. The methyl red test is usually positive at
35`C and negative at 22`C. ... Acetylmethylcarbinol is
usually produced from glucose at 22-28`C but may not be
produced at 35`C. |
