Bacillus cereus Biochemical Identification Kit – confirmation of typical colonies
The Bacillus cereus Biochemical Identification Kit confirms typical colonies from MYP or chromogenic agar with a set of miniaturised biochemical tests inoculated from one suspension.
- Miniaturised biochemical tests
- One suspension for all wells
- 10 tests
How Bacillus cereus Biochemical Identification Kit works
A pure colony is suspended and dispensed into the wells. The reactions develop during incubation and are compared with the profile of Bacillus cereus given in the instructions.
Applications and practical notes
Bacillus cereus forms heat-resistant spores and toxins and is counted in rice, starchy foods, dairy products, spices and ready meals according to ISO 7932 and the FDA BAM Chapter 14. Typical applications include:
- Cooked rice, pasta and starchy foods
- Milk powders, dairy products and infant foods
- Spices, herbs and dried ingredients
- Ready meals and catering samples
Working with Bacillus cereus Biochemical Identification Kit: Use a pure, young culture from a non-selective agar and read the wells at the time stated in the instructions.
Good practice with rapid tests: store the kit as stated on the label, let the components reach room temperature before use and use each item only once. Record the lot number and the result, and confirm positive results according to the reference method when this is required.
About the Bacillus cereus method: presumptive Bacillus cereus is counted according to ISO 7932 on Mannitol Egg Yolk Polymyxin (MYP) Agar: typical colonies are pink (mannitol not fermented) and surrounded by a precipitate of hydrolysed lecithin. Selected colonies are confirmed by haemolysis on blood agar. The FDA BAM Chapter 14 adds tests that separate B. cereus from B. thuringiensis by its toxin crystals. COLO.Science offers media, supplements, identification kits and QC strains for the whole procedure.
