Colonies are thin, white or cream-coloured but later become yellow; colonies up to 2
mm in 24 hours. Grow on medium ( peptone, yeast extract, MgSO4. 7H2O, sea water,
distilled water) at 24 ºC. Grow between 4-25 ºC and pH 4.5-9.5.

Positive results for gas and acid production from D-glucose, production of H2S, production of indole, nitrate reduced, maltose
utilization for fermentation, sucrose utilization for fermentation, glucose utilization for fermentation and phenylalanine deaminase.
Negative results: cannot use lactose, arabinose, gelatin, casein or starch for fermentation , urease, catalase, oxidase and lysine
decarboxylase.
