詳細

MacConkey broth is a selective culture medium containing lactose. Upon degradation, lactose forms acid and gas, indicating the presence of E. coli. The gas formed is collected in Durham tubes. A change in the color of the pH indicator bromocresol purple to yellow indicates acid production. Ox bile promotes the growth of several species of intestinal bacteria and inhibits the growth of other microorganisms that do not inhabit the intestine.

アプリケーション

MacConkey broth is suitable for presumptive tests for Escherichia coli and coliform bacteria and for determining the E. coli or coliform titer of milk, water, and other materials. This medium complies with the specifications given by the harmonized methods of EP, USP, JP for Microbial Examination of Non-sterile Products: Tests for Specified Microorganisms.

特徴および利点

  • Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment.
  • Excellent wettability, solubility, and free flowing properties
  • Convenient, with minimal component separation and clumping, even under warm or humid conditions
  • High batch-to-batch reproducibility
  • Prolonged shelf life of up to five years
  • High number of test strains exceeding all regulatory demands
  • Granulation technology allowing many supplements to be included, with no need to add these separately

脚注
