MAST E. coli O157 Selection Sorbitol MacConkey Agar – 500g

MAST Sorbitol MacConkey Agar 500g is a selective and differential microbiological culture medium used for the presumptive identification of Escherichia coli O157:H7. It is supplied as a dehydrated powder for preparation in microbiology laboratories. Mast Unlike conventional MacConkey Agar, Sorbitol MacConkey Agar uses sorbitol to help distinguish typical non-sorbitol-fermenting E. coli O157:H7 colonies from many other E. coli strains. It is suitable for clinical, food, public-health and research microbiology applications.
