8-hydroxyquinoline-beta-D-glucuronide (HQG) was used to improve the presumptive identification of Shiga toxin-producing Escherichia coli O157 (STEC O157) on sorbitol MacConkey agars (SMAC). Advantages of HQG are (i) that it is less expensive than 5-bromo-4-chloro-3-indoxyl-glucuronide; (ii) that it is visible in

The use of 8-hydroxyquinoline-beta-D-glucuronide for the demonstration of beta-glucuronidase activity within the family Enterobacteriaceae has been investigated. The compound has been shown to be an effective substrate for the bacterial enzyme and the Michaelis constant for the association has been
