General description

Universal Food pathogen ID Membranes are substrate-carrying membranes used for rapid identification and differentiation of food pathogens 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. This economical, confirmatory and rapid identification method is suitable for microorganisms from various food, dairy, fish, and meat products.

Application

Universal Food pathogen ID Membrane is recommended for detection of food pathogens such as E. coli, E. coli O157:H7, Staphylococcus aureus, Salmonella, Bacillus, Listeria, and Shigella species, etc. from various food, dairy, fish, and meat products. They find their application in various sectors such as the water, food, and dairy industry.
