Intended Use
For the selective separation and enumeration of enterococci in food and water.
Principle and Interpretation
Tryptone and peptone are the sources of nitrogen and essential growth factors. Yeast extract acts as well nitrogenous compounds and additionally the vitamin B12 complex. Sodium azide acts largely inhibits the growth of gram-negative bacteria while sparing enterococci, staphylococci and streptococci. Ox bile inhibits most gram positives but not enterococci. Enterococci hydrolyse esculin to esculetin and dextrose, which reacts with ferric citrate producing a brownish black precipitate around the colonies. Tolerance to bile and the ability to hydrolyze esculin is the traditional and reliable test for the identification of enterococci. (4). Sodium chloride maintains the osmotic balance of the medium and Agar is the solidifying agent.

Cerillo’s Stratus Plate Reader is a third party module that can be placed next to or inside the OT-2 or Opentrons Flex for post experimental analysis. The worktable adapter will allow you to utuilize the OT-2 or Opentrons Flex to prepare the samples directly into the plate reader positions on the worktable.
This small portable device is primarily for microbial growth curve analysis. The Stratus is compatible with Cerillo’s Canopy wireless device that allows real time visualization, control, and analytics. This product is compatible with reading 600nm wavelengths.
