method for detecting a food spoilage microbe and kit for detecting food spoilage microorganisms

摘要

a method for detecting a food spoilage microbe in a food sample, which comprises placing a food sample in contact with a peptide substrate comprising a fluorescent agent having an emission wavelength of 650 to 900 nm, an agent non-fluorescent which has an absorption wavelength of 650 to 900 nm, to suppress said emission of said first fluorescent agent, and a cleavage site located between said fluorescent agent and said non-fluorescent agent, b) monitor fluorescence of the sample containing the peptide substrate in step a), in which an increase in fluorescence is indicative of the presence of food spoilage microbes.
