General description

Differential Coli-E. coli ID Membranes are substrate-carrying membranes used for rapid identification and differentiation of E. coli, Klebsiella, Pseudomonas, and Salmonella species in food and environmental samples through characteristic color reactions by placing on the agar surface post-incubation. The membranes contain chromogenic substrates such as ONPG, X-Gal, or X-Glu, and other substrates and indicators, which serve as the basis for microbe differentiation by color. The target organisms possess enzyme systems that metabolize the substrates in the membrane, leading to a change of color. The colors can be visually detected on the membrane. This indicates microbial enzymatic activity which serves to identify the genus and species.

Application

Differential Coli-E. coli ID Membrane is recommended for detection of E. coli, Klebsiella, Pseudomonas, and Salmonella species in the food and environmental samples. They find their application in various sectors such as the food and dairy industry, water industry, pharmaceutical laboratory testing, cosmetic industry, environmental and sanitary testing, clinical diagnostic, etc.
