Selective medium for detection of Cronobacter (formerly Enterobacter sakazakii) in milk powder and powdered infant formulae. Application: Use 30.7 g for 1 l agar
Egg Yolk Emulsion is used as supplement in nutrient agars for detection of lecithinase activity in microbial colonies. Herewith, bacterial species like Bacillus cereus and Clostridium perfringens, or Staphylococcus aureus may be identified. The lecithinase activity can be noted by formation of light, sometimes whitish halos surrounding the colonies.
Application: The ISO 7932 recommends a final concentration of 10 % emulsion in the prepared medium in general, e.g. in Mannitol Egg Yolk Polymyxin Agar (Base) (Art. No. 5765.1) for examining the lecithinase activity of Bacillus cereus.
We recommend using TSC Agar (Base) (Art. No. CL51.1), Mannitol Salt Agar (Art. No. CL81.1) or Palcam Listeria Agar (Base) (Art. No. 5768.1) for base agar with the addition of 5 % emulsion.
Add after autoclaving.
Water-soluble. Produced through aqueous extraction of autolysed brewer´s yeast. High content of vitamins. Ideal, therefore, in many standard nutrient media, e.g. LB-medium as for vitamins, carbohydrates, and amino acids.
For confirmation of Pseudomonas aeruginosa in water samples.Application: Use 38 g for 990 ml agar. Add 10 ml glycerol.
For differentiation of gram-negative enterobacteria.Application: Use 52 g for 1 l agar.Double Sugar Iron Agar, KIA
