Staphylococcus Medium 110

Staphylococcus Medium 110, also known as Stone Gelatin Agar, is used for isolating and differentiating staphylococci based on mannitol fermentation, pigment formation and gelatinase activity.

Principles Staphylococcus Medium 110 contains peptone as a source of carbon, nitrogen, vitamins and minerals. Yeast extract supplies B-complex vitamins which stimulate bacterial growth. Sodium chloride, in high concentration, inhibits most bacteria other than staphylococci. Lactose and D-mannitol are the carbohydrates. Gelatin is included for testing liquefaction. Agar is the solidifying agent.

Pathogenic staphylococci (coagulase-positive staphylococci) typically resist the high salt concentration and form colonies with a yellow-orange pigment. These organisms typically ferment mannitol and produce acid, and liquefy gelatin, producing zones of clearing around the colonies.
