An Experimental Insight into Extracellular Phosphatases - Differential Induction of Cell-Specific Activity in Green Algae Cultured under Various Phosphorus Conditions.

Extracellular phosphatase activity (PA) has been used as an overall indicator of P depletion in lake phytoplankton. However, detailed insights into the mechanisms of PA regulation are still limited, especially in the case of acid phosphatases. The novel substrate ELF97 phosphate allows for tagging PA on single cells in an epifluorescence microscope.
