High grade Coagulase Mannitol Agar Base is supplied by Micromaster. It is available in the form of a light yellow to light grey coloured homogeneous free flowing powder with a pH in the range of 7.2 to 7.6. For maximum efficiency, it must be stored below 30C in tightly closed container.

Quantity provided: 500g /pack

Coagulase Mannitol Agar Base is recommended for the primary isolation and differentiation of pathogenic Staphylococci from clinical specimens or for classifying pure cultures. Staphylococci are generally found on the skin and mucous membranes of humans and other animals. Some of the pathogenic staphylococci in both humans and animals produce an enzyme called coagulase and detection of this enzyme is used in the laboratory to identify these organisms. This media is used for the isolation of Staphylococcus aureus from clinical specimens and for differentiation of S.aureus from other species on the basis of coagulase production and mannitol fermentation. Coagulase production is dependent on the presence of a fermentable sugar like mannitol in this case. It is also dependent on the presence of a protein factor in the brain heart infusion and blood plasma. When mannitol is fermented, the pH of the medium surrounding the coagulase positive colonies drops. This drop in pH is indicated by the change in colour of the bromocresol purple indicator, which turns yellow and exhibits yellow zones around the colonies.
