Filtration and Buoyant Density Characterization of Algal Alkaline Phosphatase

Many planktonic algae and bacteria respond to acute orthophosphate limiting conditions by synthesizing alkaline phosphatase (APase). This class of enzymes permits biota to hydrolyze dissolved phosphomonoester substrates present in the water column, thereby providing an additional source of orthophosphate for biotic assimilation (Berman, 1970; Heath and Cooke, 1975; Francko and Heath, 1979; Pettersson, 1980; Wetzel, 1981; Heath, 1986; Francko, 1986a). As such, APase plays a central role in the overall process of phosphorus recycling and orthophosphate regeneration in epilimnetic waters (reviewed by Franko, 1986a).
