Coliform group bacteria and Escherichia in microbiological analysis

coli search and counting as selective solid media

E. coli colonies appear as blue-green. The accompanying flora is suppressed by bile salts.

Incubation at 44°C is another factor that suppresses the accompanying flora.

For E. coli analysis in processed foods, it is recommended to increase the incubation temperature to 44 °C after 4 hours of resuscitation at 30-37 °C and incubate for 18-20 hours.
