Petrifilm® Rapid E.coli/Coliform Count Plates – Ready-to-Use Culture Medium for E. coli and Coliform Enumeration

Petrifilm® Rapid E.coli/Coliform Count Plates is a ready-to-use culture medium system designed for rapid and reliable enumeration of E. coli and coliform bacteria in food safety and quality control laboratories. Manufactured by Neogen®, these plates require minimal preparation compared to conventional agar methods and deliver results within 18-24 hours.

The plate contains BCIG (5-bromo-4-chloro-3-indolyl-β-D-glucuronide) and tetrazolium indicators. BCIG detects β-glucuronidase enzyme activity specific to E. coli, enabling blue-colored colonies surrounded by gas bubbles to appear distinctly for E. coli identification. Coliform bacteria appear as red-colored colonies surrounded by gas production. This color differentiation allows simultaneous enumeration of both E. coli and total coliforms on a single plate in a single step.

Approved by AOAC® OMA #2018.13 and MicroVal certified (No. 2017LR76), ensuring compliance with official analytical methods. Widely preferred for routine microbiological testing of food, beverage, and environmental samples.
