Abstract
A composition for use in a medium for detecting yeasts and molds in a test sample, the composition comprises a substrate for an aminopeptidase; and a signal moiety linked to the substrate, the signal moiety capable of providing a detectable signal when cleaved by aminopeptidase in yeasts or molds. Optionally, an aminopeptidase inhibitor is added to the composition, to reduce endogenous enzymatic activity in samples. A method for use of the composition to detect the presence or amount of yeasts and/or molds in a test sample comprises inoculating a medium comprising the composition of claim 1 with said test sample; incubating the inoculated medium under conditions suitable for the growth of yeasts or molds; and, observing any detectable signal, whereby the presence of a detectable signal indicates the presence of yeasts or molds in the test sample.
