| Preparation Note: | Directions: Dissolve 0.56 g Acetamide Nutrient Broth Part A and 2 g Acetamide 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. |
