Colonies of aerobic bacteria exhibit clear red color using a redox indicator.


1. Easily distinguishable brightly colored colonies

Colonies turn red, making them easy to visualize and count, even in the presence of food residue or other source of color.

2. Reducing the spreading of colonies of Bacillus spp.

Colonies of Bacillus spp. that can easily spread on conventional agar media but spreading is controlled on Easy Plate.

3. High correlation with the plate count agar

High correlation with the plate count agar in various foods.

Plate Count Interpretation

  1.  Count any colonies that spread as single colony, counting by the central dark area of the colony.
    *Do not count thin, microscopic colonies scattered across an area where a colony is spread out.
  2. Where multiple colonies are present, count the central dark area of the colony as a single colony. In example B, there are 4 dark area of the colony. This would be counted 4 colonies.
