MacConkey + Crystal Violet Agar – medium for Enterobatteriaceae isolation and Shigella identification acc. to Harmonized Pharmacopeia

  • Format: 500 g
  • Code: TN1075
  • Technology: Culture media and ISO confirmation tests
  • Application: Food/Water microbiology
  • Tag/Filter: Escherichia coli and coliforms

This medium is used to isolate and enumerate enterobacteriaceae, and particularly Escherichia coli in the testing of microbial contamination of non-sterile Pharmacopeia products. It is also part of a food microbiology standard method (ISO21567 – Horizontal method for the detection of Shigella spp.). The principle of the medium rests on the ability of coliforms to ferment lactose (brick-red colonies). Other Enterobacteriaceae forms honey-coloured colonies. Due to the presence of bile salts and crystal violet this medium inhibits Gram-positive bacteria.
