2155 Alkaline Saline Peptone Water ISO, Condalab

This medium leverages the unique ability of Vibrio species to tolerate and thrive in environments with high alkalinity and elevated salt concentrations, which typically inhibit most other competing bacteria. The Enzymatic Digest of Casein (Peptone) provides the necessary nitrogen, vitamins, and amino acids for bacterial growth. The high concentration of Sodium Chloride (20.0 g/L) provides the halophilic conditions required by many Vibrio species. The alkaline pH (8.6 ± 0.2) acts as a selective agent, as most other commensal microorganisms found in food or water cannot grow at such high pH levels. This enrichment step is crucial for increasing the population of Vibrio prior to subculturing onto selective solid media like TCBS Agar.

Advantages

• ISO Standard Compliance: Strictly formulated according to ISO 21872 for the horizontal method for the detection of Vibrio spp.
• High Selectivity: The combination of high pH and high salt concentration effectively suppresses the growth of Enterobacteriaceae and other competitive flora.
• Optimized for Halophilic Species: Specifically balanced to support the growth of Vibrio parahaemolyticus and Vibrio vulnificus.
• Excellent Enrichment: Allows for the recovery of Vibrio cells even when present in low numbers in complex environmental or seafood matrices.
• Stable Formulation: Provides a reliable and reproducible environment for the primary enrichment phase of the detection protocol.
