Slanetz-Bartley Medium ISO 7899-2 500g Condalab 1109

Slanetz-Bartley Medium is a very selective medium for enterococci. A demonstration by Burkwall and Hartman showed that the addition of .5ml of Tween 80, and 20ml of a 10% Sodium Carbonate or Bicarbonate solution to each litre of the medium was valuable to investigating enterococci in frozen foods. Tryptose provides nitrogen, vitamins, minerals, and amino acids that essential for growth and the yeast extract is a source of vitamins of the B-group. Glucose is the fermentable carbohydrate providing carbon and energy and dipotassium phosphate is used as a buffer. Sodium azide inhibits Gram-negative bacteria triphenyl tetrazolium chloride is reduced to formazan by the enterococci. Bacteriological agar is the solidifying agent. It is prepared according to ISO 7899-2.

This medium also complies with the recommendations of the British Ministry of Health – Report 71, and the German DIN Regulations 10181 and 10160 for the examination of milk, meat, and meat products.
