Used in combination with a variety of selective agents and incubation conditions a wide range of specific organisms can be isolated.

With careful raw material selection of the various media components E&O can ensure a consistent level of quality and performance.

For each formulation the necessary ingredients are accurately weighed, combined and blended together to produce a homogenous powdered product.

Bacillus cereus Agar (Mannitol Egg Yolk Polymyxin (MYP))

PP0050

Bacillus cereus (MYP – Mannitol Egg Yolk Polymyxin) Agar is intended for the selective enumeration of Bacillus cereus in food samples the medium uses two reactions (Mannitol fermentation and Lecithinase production) to differentiate B. cereus from other members of the species. As B. cereus is mannitol-negative the colonies are pink in colour due to the presence of phenol red. Lecithinase production (from egg yolk) is indicated by a white precipitate around the colonies. Polymyxin is added as the selective agent to inhibit coliforms.

NB: It should be noted that some Proteus spp. and Gram-positive cocci may grow on this medium.
