Description

Application

Synthetic medium to detect microbial utilization of acetamide. Corresponds to the suggestions of the "Deutsches Institut für Normung (DIN)" and the test procedures set out in §35 LMBG for the examination of water for Pseudomonas aeruginosa.

Preparation Note

Dissolve 2.56 g in 950 ml distilled water. Check the pH and if necessary adjust. Make up to 1 litre and pour into tubes. Autoclave at 121°C for 15 minutes.
Technique:Medium is inoculated with a couple off loops from the culture to be assayed and it is incubated at 32-35°C for 24-48 hours before.going to the isolation medium.To confirm Ps. aeruginosa, inoculate a loop of culture in Asparagine Proline Broth (Cat. No. 17129) and incubate at 35-37°C for 24 hours. After this period, pour 1-2 drops of Nessler′s Reagent (Cat. No. 72190) on to the culture and verify ammonia production: a change to yellow will mean ammonia production positive and therefore, Ps. aeruginosa presence.

Pseudomonas Media and Tests

Pseudomonas are motile (one or more polar flagella), rod shaped and aerobe Gram-negative bacteria. They are found almost everywhere, in soil, water, plants and animals. In most cases it is not pathog...
