Compact Dry ETC
- Ready and easy to use portable plate: Preparation of medium is not required, which eliminates waste of medium as well as sterilizing apparatus to prepare the medium.
- Detection of colonies on plate is simple and clear.
- Single colonies on the plate can be isolated for further identification tests
Ready-to-use petri dishes for reliable microbiological analysis for Enterococci
Compact Dry ETC is a ready to use, selective and chromogene plate for the detection and enumeration of Enterococcus. Enterococci are Gram-positive organisms that, like the Gram-negative Enterobacteriaceae, belong to the intestinal bacteria. They can occur as contamination in various fermented food products. The presence of enterococci in food has long been considered the main indicator of poor hygiene conditions in the production process. On the other hand, enterococci are used as starter cultures for specific fermentation processes. It is known that enterococci play an important role in the development of the sensory properties of fermented food products. The presence of enterococci in drinking water is considered an indicator of fecal contamination. Enterococci can only get into the water via human or animal faeces.
The Compact Dry ETC medium contains X-glucoside (X-Gluc) as a chromogenic indicator and specific antibiotics for selective cultivation.
Incubation time and temperature: 20 - 24 hours at 37 ± 1 °C
Shelf life: 18 months after manufacturing.
Storage: At room temperature (+ 1 to + 30 °C).
Specimen pretreatment
Viable count in water or liquid foodstuff
Drop 1 ml of specimen (dilute if necessary) on the middle of the Compact Dry plate.
Viable count in solid foodstuff
Add buffer solution to the specimen and homogenize by stomacher®. Drop 1 ml of specimen (dilute if necessary) on the middle of the dry sheet of the Compact Dry plate.
Viable count in swab test specimen
Use the swab to wipe the surface, put into the device with wiping solution. Drop 1 ml of wiping solution (dilute if necessary) on the middle of the Compact Dry plate. It is recommended to use Swab for Compact Dry offered by HyServe Id-No. 1 002 952/3 (40/240 pieces).
Test instructions
Open the cap and drop 1 ml of specimen on the middle of the Compact Dry plate.
Specimen diffuses automatically and evenly into the sheet and transforms the dried sheet into a gel within seconds.
Put the cap again on the plate and write the information needed on the memorandum section.
Turn over the capped plate and put in the incubator.
After incubation count the number of blue/blue green colored colonies underneath the plate. White paper placed under the plate helps to count the colonies.
