  • Code: 05001
  • Packaging: 10 plates/ box or as per customer request.
  • Storage Conditions: 2–8°C.
  • Transportation: Ambient temperature.
  • Shelf Life: 04 months from the date of manufacture.
INTENDED USE
  • BacterPlate™ Plate Count Agar (PCA) containing glucose and yeast extract is used in food bacteriology to enumerate aerobic bacteria in milk, meats, meat-based products, other food products, as well as for the analysis of pharmaceuticals, cosmetics and their associated raw materials.
  • It is also used for the enumeration psychrotrophic microorganisms.
  • The typical composition corresponds to that defined in the standards NF EN ISO 4833-1 & 2, NF ISO 17410, XP V08-034; T90-425 and ISO 14461-1.
  • The packaging with semi-permeable Cellophane film helps balance the humidity of the environment during storage.
PRINCIPLE
  • The nutrients supplied by Tryptone, vitamins from yeast extract, and glucose used as energy source favor the growth of most bacteria. In dairy bacteriology, it is recommended to add 1 g of powdered skim milk per liter of reconstituted media (PCA with Skimmed Milk)

Surface inoculation (NF EN ISO 4833-2):

  • Dry the plates in an incubator with the covers partially removed.
  • Transfer 0,1 mL of the sample to test to the surface of the BacterPlate™ Plate Count Agar (PCA) along with its serial dilutions.
  • Inoculate the plate by using a sterile triangle.
  • Incubate at 30 ± 1°C for 72 ± 3 hours.

NOTE:

  • A spiral inoculation system can also be used.
  • For the detection of psychrotrophic bacteria in foods (NF ISO 17410), incubate the plates for 10 days at 6,5 °C.

RESULTS

  • Count plates containing less than 300 colonies
