Claims 1 and 14 are illustrative of the subject matter on appeal and read as follows:
1. A method for detecting the presence or measuring the concentration of
bacteria in a food product, comprising the steps of:
providing a bacterial growth medium formulated for food testing, which comprises a
first enzyme substrate for a phosphatase, a second enzyme substrate for a glycosidase,
and a third enzyme substrate for a peptidase, wherein said first, second and third enzyme
substrates cause or produce an identical type of detectable signal when hydrolyzed by
their respective enzymes;
inoculating said medium with said food product and incubating said medium under
conditions suitable for bacterial growth for a period of time; and,
detecting or measuring the identical type of detectable signal as an indication of the
presence or the concentration of bacteria in said food product.
14. A method for detecting the presence or measuring the concentration of
bacteria in a food product, comprising the steps of:
providing a bacterial growth medium formulated for food testing, which comprises a
first enzyme substrate for a glycosidase and a second enzyme substrate for a peptidase,
wherein said first and second enzyme substrates cause or produce an identical type of
detectable signal when hydrolysed by their respective enzymes;
inoculating said medium with said food product and incubating said medium under
conditions suitable for bacterial growth for a period of time; and,
detecting or measuring the identical type of detectable signal as an indication of the
