Description

Chromogenic medium for isolation and detection of Pseudomonas species.

The product is composed of a powder base.

MEDIUM PERFORMANCE:
1. Fast: 24 h incubation.
2. A membrane filtration method can be used for detection from 100 mL of water, the inoculated membrane (polycarbonate filter) is placed, sample uppermost, on the agar plate.

Pseudomonas spp., including P. aeruginosa → blue-green
Most of Enterobacteriaceae → mauve to violet or inhibited
Gram + bacteria → inhibited

Pseudomonas are ubiquitous bacteria found in the soil, on plants and in freshwater and marine habitats. Many strains can grow at low temperature (psychrophilic strains) and may contaminate food or pharmaceutical products stored in the refrigerator.
P. aeruginosa is a valid indicator for recreational water disinfection efficacy. This parameter is currently used as a criterion in the regulation of wading and swimming pools. Moreover, P. aeruginosa is important not only in terms of its role as an indicator, but also because it is an opportunistic pathogen whose transmission is often associated with water.

Also available in 25 L (PS833-25).
