    摘要： A test method and medium for quantitatively identifying and distinguishing biological materials in a test sample. A first biological material has enzyme specificity for a first chromogenic substrate, a second biological material has enzyme specificity for a second chromogenic substrate, and a third biological material has specificity for one of the substrates. The chromogenic substrates form respective first and second colored water insoluble compounds upon reaction with specific enzymes. The first and second biological materials are capable of fermenting a sugar, and the third biological material does not ferment the sugar. The test medium is adjusted to a pH conducive for color change of a pH indicator upon fermentation, resulting in the formation of a zone of a third color around the water insoluble compounds of the fermenting materials. Following incubation, the sample is examined for the presence of colonies of the first biological material, having the first color and an encircling zone of the third color; for colonies of the second material, having the second color and the colored zone; and for colonies of a third material having the first or second color, and not having the colored zone.

    摘要： An improved method for testing for the presence of a particular microorganism and/or group of microorganisms characterized by a particular enzyme is provided. The method uses a dye-forming and/or fluorogenic-generating substrate throughout a polymer matrix or on the surface of a solid support member that forms a colored precipitate or fluorescent by-product when cleaved by the enzyme. The precipitate is concentrated on the polymer matrix and/or solid support member to create a visible reaction product, whereas the fluorescent by-product will normally be dispersed into the surrounding medium to some extent. The amount of dye-forming substrate needed is independent of the sample size. The present invention further comprises an enzyme indicator device comprising a dye-forming and/or fluorogenic-generating substrate throughout a polymer system or on the surface of a solid support member.
