How the Pseudalert 250 test works
The Pseudalert 250 test detects the presence of Pseudomonas aeruginosa in bottled water samples.
The test is based on a bacterial enzyme detection technology that signals the presence of P. aeruginosa through the hydrolysis of a substrate in the Pseudalert 250 reagent. P. aeruginosa cells rapidly grow and reproduce using the rich supply of amino acids, vitamins, and other nutrients present in the Pseudalert 250 reagent. Actively growing strains of P. aeruginosa have an enzyme that cleaves the substrate in the reagent to produce blue fluorescence under ultraviolet light.
The Pseudalert 250 test detects P. aeruginosa at 1 cfu per 250 mL sample within 24 hours.
