CompactDry ECO is a ready-to-use plate enabling easy culture and enumeration of E. coli in solid food stuff (homogenized with buffer solution), water/liquid samples and swab based environmental testing for surfaces and production areas.
E. coli form blue colonies due to the chromogenic enzyme substrate, X-Gluc contained in the dehydrated selective media.
Precaution for interpretation:
E. coli O157 does not produce beta glucuronidase. So, E. coli O157 colonies on CompactDry ECO are not coloured and form white colonies.
CompactDry ECO is a medium to detect E. Coli
The medium contains the chromogenic enzyme substrate X-GLUC.
Blue / Blue purple: E.coli forms blue colonies
Step #1
Remove the cap
Step #2
Dispense 1 mL of sample in the middle of the CompactDry plate
Step #3
The sample diffuses passively and evenly across the dehydrated media sheet, rehydrating the dry medium into a gel within seconds
Step #4
Replace the lid and label the plate
Step #5
Turn over the plate (lid down) and incubate for the appropriate time and temperature
Step #6
Following incubation, count the number of coloured microbial colonies
