  7. Fluorescein diacetate hydrolysis - Wikipedia

    en.wikipedia.org/wiki/Fluorescein_diacetate...

    FDA hydrolysis is often used to measure activity in soil and compost samples; however, it may not give an accurate reading if microbes with lower activity phases, such as esterases, cleave the fluorescein first. It is also used in combination with propidium iodide (PI) to determine viability in eukaryotic cells. Living cells will actively ...
