M17 Agar
M17 Agar is used for the enumeration of lactococci (especially Lactococcus lactis) in dairy products. It is also used to study the sensitivity of these species to bacteriophages. It is well adapted to the enumeration of Streptococcus thermophiles in natural or flavored yogurts, textured or not, and in yogurts containing morsels of fruit.
