Bacillus Cereus MYP Agar is used with supplements for the selective and differential enumeration of Bacillus cereus from foods. Conforms to ISO and FDA / BAM formulation in a laboratory setting. MYP Agar Base is not intended for use in the diagnosis of disease or other conditions in humans.Formulated to ISO 7932:2004 MYP was introduced by Mossel and his co-workers in 1967 for the enumeration of Bacillus cereus in foods and was shown to be the most effective for this purpose by Inal in 1972. B. cereus is differentiated from other members of the Bacillus group by two reactions: mannitol fermentation and lecithinase production. Mannitol fermentation on this medium produces a yellow color. B. cereus is mannitol negative and produces red colonies. The lecithinase production of B. cereus is indicated by a white precipitate around the colonies.For more information visit https://www.neogen.com/solutions/Microbiology/bacillus-cereus-myp-agar
