Method and components for the detection of yeasts and/or molds in a sample
First Claim
1. A composition for use in a medium for detecting yeasts and molds in a test sample comprising:
- a) a substrate for an aminopeptidase, wherein a signal moiety is linked to the substrate and said moiety is capable of providing a detectable signal when cleaved by said aminopeptidase in yeasts or molds;
b) an antibiotic capable of inhibiting the growth of bacteria in said sample; and
c) an inhibitor of aminopeptidase endogenous to the test sample in an amount effective to suppress endogenous aminopeptidase activity in said sample suspected of containing yeasts or molds.

Abstract
A composition and method for detecting the presence or amount of yeasts and molds in a test sample is presented. The composition contains a substrate and an inhibitor for an aminopeptidase. The substrate has a signal moiety capable of providing a detectable signal when cleaved by an aminopeptidase in yeasts or molds. The aminopeptidase inhibitor serves to reduce the endogenous aminopeptidase activity in the test sample. The method to detect yeasts or molds in a sample includes inoculating a test sample with the disclosed composition, incubating the sample and observing any detectable signal that indicates the presence of yeasts or molds.
