Description |
This medium for the selective enrichment of staphylococci was formulated by Giolitti and Cantoni in 1966. The growth of staphylococci is promoted by pyruvate, glycine and above all by a high concentration of mannitol. Gram-negative contaminants are inhibited by potassium tellurite. Micrococci are suppressed by a certain degree of anaerobiosis. Growth of staphylococci can be recognized by a black colourising of the culture medium due to reduction of tellurite to metallic tellurium. The prepared culture medium base can be stored for about 2-3 weeks in the refrigerator. The ready-to-use medium must be used on the day on which it is prepared. It is advisable that the basic medium be degasified at the moment of use by heating for 15 minutes at 100°C, cool rapidly and add sterile potassium tellurite solution. |
Application |
Liquid medium for enumeration acc. to the MPN method, and for the selective enrichment of staphylococci from food acc. to ISO and IDF standards. |
