How the Enterolert 250 Test works
The Enterolert 250 Test uses proprietary Defined Substrate Technology (DST) nutrient indicator to detect enterococci. The Enterolert 250 Test provides confirmed presence/absence results in 24 hours. The Enterolert 250 Test utilizes orth-nitrophenyl-ß-D-glucoside as a nutrient indicator and incorporates a specifically designed blue background color in its formulation.
When the substrate is metabolized by enterococci, the sample turns from blue to green to indicate detection. Any change from the original color to green is considered a positive result. No ultraviolet light source is required. The Enterolert 250 Test detects enterococci at 1 cfu in 250 mL bottled water samples in 24 hours.
