Cronobacter spp. (spp.)

Descrição geral

Cronobacter Selective Broth (CSB) contains high nutrient content with an enzymatic digest of animal tissue and meat extract creating good growth conditions for Cronobacter. Vancomycin inhibits the growth of Gram-positive flora, and sodium chloride maintains the osmotic balance of the medium. Upon fermentation of sucrose, Cronobacter produces a color change of the bromocresol indicator. However, this reaction is not always positive for Cronobacter in the given incubation time. Hence, it is necessary that every selective enrichment in CSB must be sub-cultured on Chromogenic Cronobacter Isolation (CCI) agar regardless of its color change.

Aplicação

Cronobacter Selective Broth is suitable for the selective enrichment of Cronobacter spp. from food products and ingredients intended for human consumption and the feeding of animals and environmental samples in the area of food.

Características e benefícios

  • Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment.
  • Excellent wettability, solubility, and free flowing properties
  • Convenient, with minimal component separation and clumping, even under warm or humid conditions
  • High batch-to-batch reproducibility
  • Prolonged shelf life of up to five years
  • High number of test strains exceeding all regulatory demands
  • Granulation technology allowing many supplements to be included, with no need to add these separately

Nota de rodapé

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
