ABSTRACT:
The invention provides a method for the rapid detection of biotoxic contaants in a test material comprising combining a sample of the test material with activated spores essentially devoid of detectable enzymatic activity, which activity becomes manifest and increases measurably following germination of the spores and with at least one germinant capable of triggering germination of the spores and a substrate which is catalytically convertible to a product by the enzymatic activity, incubating the mixture for a period of less than one hour to accelarate germination of the spores, increase of the enzyme activity, and a catalytic conversion of the substrate, and detecting the formation of the product of the catalytic conversion of the substrate and the enzyme, the level of the product being maximal in the absence of any biotoxic contaminants, and decreasing in direct proportion to the toxicity of contaminants in the test sample.
