E.coli Count Plate

1. Product Overview

FSTest E.coli Count Plate is a ready-to-use, single-use dehydrated culture medium system engineered for the rapid, precise, and cost-effective detection and enumeration of Escherichia coli (E. coli) in food, beverage, and environmental samples.

Utilizing an advanced β-glucuronidase chromogenic enzymatic reaction, E. coli colonies hydrolyze the substrate during incubation to form distinct blue-green colonies. This eliminates the labor-intensive process of traditional agar media preparation (boiling, autoclaving, pouring plates) while providing clear, error-free visual interpretation.

2. Key Benefits

• Fast Time-to-Result: Delivers definitive colony counts in just 18–24 hours, saving up to 24–48 hours compared to traditional culture and MPN methods.

• Ready-to-Use & Zero Media Prep: No glass Petri dishes, autoclaving, or agar preparation required—simply inoculate, incubate, and read.

• High Sensitivity & Accuracy: Detection limit as low as 1–10 CFU/mL (g), ensuring compliance with strict international food hygiene standards.

• Unambiguous Visual Reading: Highly specific chromogenic reaction produces vivid blue-green colonies, drastically reducing manual counting errors and false results.

• Space & Cost Efficiency: Ultra-thin paper-film format takes up minimal storage and incubator space, while significantly reducing biohazard disposal waste and shipping costs.

• Flexible Transport & Long Shelf Life: Stable at ambient temperatures (up to 15 days of room temperature shipping without cold chain reliance) with a 18-month shelf life under standard refrigeration.

5. Test Procedure

6. Performance & Validation

• Target Specificity: Successfully detects up to 94% of E. coli strains expressing the β-glucuronidase enzyme.

• Known Assay Limitations: Strains that naturally lack the β-glucuronidase enzyme (such as E. coli O157:H7) will not produce blue-green colonies on this substrate. For pathogenic strain screening (e.g., O157:H7), specific pathogen detection kits or molecular testing should be used.
