About 97% of E.coli strains are thermotolerant and produce beta-glucoronidase, an enzyme that reacts with BCIG indicator in 3M™ Petrifilm™ Select E.coli count plates to produce dark green to blue-green colonies. 3M™ Petrifilm™ SELECT E.coli Count Plates will not detect E.coli O157 as most strains are atypical. They are glucuronidase negative, and will not produce a blue-green colony.
