Fluorimetry is widely used by the dairy industry to verify whether pasteurization has been successful. This is done using a reagent which is hydrolysed to a fluorophore and phosphoric acid by alkaline phosphatase in milk. If pasteurization has been successful then alkaline phosphatase will be entirely denatured and the sample will not fluoresce. This works because pathogens in … WebDec 18, 2024 · Fluorimetry is one of the widely used tools in detecting and analyzing different phytoplankton species by measuring the fluorescence signals emitted from the photopigments [ 5 ].
