General description

Universal Microbial Limit Test Membrane are substrate-carrying ID membranes used for rapid identification and differentiation of colonies 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 water, food, environmental, and clinical samples.

Application

Universal Microbial Limit Test Membrane is recommended for the detection of pathogenic microorganisms such as E. coli, S. aureus, P. aeruginosa, Bacillus, and Salmonella species from pharmaceutical preparations, raw materials, cosmetic samples, etc. 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.
