Dehydrated Culture Media products are formulated to supply the required nutrients to allow for the growth of microorganisms.

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.

Bacillius cereus Selective Agar (PEMBA)
This is a medium for the selective isolation and enumeration of Bacillus cereus in food samples. It is said to be particularly suitable for the detection of small numbers of Bacillus cereus particularly in the presence of other contaminating organisms. The medium is made selective by the inclusion of Polymixin and Sodium Pyruvate is also present which is said to improve Egg Yolk precipitation and enhance sporulation. As Bacillus cereus is Mannitol Negative the colonies are bluish in colour, due to the presence of the Bromothymol Blue Indicator, with a surrounding precipitate of the same colour due to Lecithinase production (from the Egg Yolk).

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