General description
MUG EC broth is a selective and differential liquid culture mediumspecifically formulated for the rapid detection of Escherichia coli inmicrobiological samples. The medium is based on EC broth components—caseinenzymatic hydrolysate as the source of essential nutrients, lactose as afermentable carbohydrate, bile salts, buffer salts, and sodium chloride tomaintain osmotic equilibrium—and is supplemented with the fluorogenic substrate4‑methylumbelliferyl β‑D‑glucuronide (MUG). MUGis hydrolyzed by the E. coli enzyme β‑glucuronidase to yield the fluorescent product 4‑methylumbelliferone, which can be observed under long‑wave UV light, enabling rapid and specific detection of E. coli. Caseinenzymic hydrolysate provides essential nutrients. Lactose is a fermentablecarbohydrate. Sodium chloride maintains the osmotic equilibrium. The medium’sstrong buffering system controls pH during fermentative activity, while bilesalts inhibit gram‑positive bacteria,particularly Bacillus species and fecal streptococci, enhancingselectivity for E. coli.
Application
用于荧光法检测大肠杆菌。
