Descrição
Agar de contagem de placas com leite desnatado para microbiologia GranuCult® Merck
RENDIMENTO 20,0g/l
EMBALAGEM 500GR
The culture medium complies with the recommendations of the International Dairy Federation (Internationaler
Milchwirtschaftsverband) (1991) and the DIN Norm 10192 for the examination of milk and dairy products.
Mode of Action
Addition of skim milk to a culture medium with a superior nutrient base optimally adapts it to the neutral conditions experienced by microorganisms which grow in milk. More colonies grow and a wider range of bacteria can be cultured than in other culture media intended for the same purpose (TERPLAN et al. 1967).

Peptone from casein 5.0;
yeast extract 2.5;
skim milk powder (no inhibitors) 1.0;
glucose 1.0;
agar-agar 10.5.
Preparation
Suspend 20.0 g/litre in cold water and allow to stand for about 15 minutes. Transfer flask to a cold water bath and heat gently, with frequent shaking, until completely dissolved, then autoclave (15 min at 121 °C).
pH: 7.0 ± 0.2 at 25 °C.
The plates are clear to opalescent and yellowish.
The reconstituted culture medium is more or less opalescent.
According to DIN it can be stored for up to 3 months in the refrigerator, the temperature should not exceed 5°C.
