Question
What Quality Control (QC) Organism should be used for m-Endo, m-FC, and m-ColiBlue24™ media?
Summary
QC organisms for micro plates m-Endo, m-FC, and m-ColiBlue24™.
Answer
E. Coli ATCC 25922 is the primary organism that should be used to QC m-FC, m-Endo, and m-ColiBlue24™ micro broths.
E. Coli ATCC 25922 is not an item that can be purchased through Hach and will need to be obtained through an alternate source.

This organism will work well for each test unless the culture is old. In the case of older cultures it will not work as well on m-FC media.
