Thermo Scientific™ Oxoid™ Alkaline Peptone Water, CM1028

Manufacturer: THERMO FISHER


Enrich and recover Vibrio species from food, water, and clinical samples with Thermo Scientific™ Oxoid™ Alkaline Peptone Water. This medium is selective by exploiting the ability of Vibrio species to tolerate alkaline conditions and high sodium chloride levels. The peptone content provides the conditions for growth and recovery of Vibrio species, supplying vitamins, minerals, and nitrogen in the form of amino acids.

Use Alkaline Saline Peptone Water (ISO) for selective recovery and enrichment of Vibrio species.

  • Creates strong alkaline and high sodium conditions to provide a selective environment for Vibrio
  • Can be used for direct microscopic examination of samples using the hanging drop method

Alkaline Peptone Water was first formulated by Shread, Donovan and Lee1 to be used as a non-selective enrichment broth for the cultivation of Aeromonas spp. Cruickshank reported that when the pH is raised, the medium can be used to effectively cultivate Vibrio species.2 The 2% (w/v) sodium chloride incorporated in this medium promotes the growth of Vibrio cholerae, while the alkalinity of this medium inhibits most of the unwanted background flora.
