CHROMagar™ Liquid ECC - 5000 ml

Description

Chromogenic medium for the simultaneous detection and enumeration of ß-glucuronidase positive E. coli and coliforms in water samples.

The product is composed of a powder medium, to be used in broth form.

MEDIUM PERFORMANCE:
1. Simplicity: Very easy to prepare compared to agar based culture media.
2. Broth technique: Innovative chromogenic culture medium to be used in broth form (without agar) within the water filtration technique, to impregnate the pad or the filter. You can take an aliquot so to prepare the exact quantity of broth you desire. Thanks to this flexibility, you get rid of the prepared media stock and shelf life management headaches and get the insurance to always work with fresh media.
3. Economic: Only 2 ml/test (instead of the 10-20 ml for other culture media).
4. Easy Method: CHROMagar™ Liquid ECC allows a simultaneous detection and differentiation between E. coli and coliforms in one medium. This is helpful to determine if there is organic contamination (coliforms) or faecal contamination (E. coli). The use of this technique involves less work in comparison with traditional methods (MI Agar).
5. Easy to read thanks to the high colour contrast between colonies. There is no mixing of both colours (contrary to other chromogenic media on the market). Colonies are either blue or purple.

TYPICAL APPEARANCE OF MICROORGANSIMS:
E. coli → blue
Other faecal coliform bacteria → purple
Other gram negative bacteria → colourless or inhibited

Coliforms, Enterobacteriacae able to ferment lactose (lactose positive Enterobacteriacae), are bacteria present in human and warm blooded animals intestinal flora, in the soil and water. Coliforms are proof of organic, environmental or faecal contamination.
aecal contamination, due to coliforms coming from animal waste, consists mainly of Escherichia coli and thermotolerant Klebsiella.
Strict regulations exist for E. coli/Coliform presence in water and food samples.
