The uptake kinetics of dissolved inorganic phosphate (/sup 31/P/sub 1/) by lake water microorganisms and a green alga (Selenastrum capricornutum) were determined as a function of uptake rates of radiophosphate (/sup 32/P/sub 1/) at added /sup 31/P/sub 1/ levels greater than or equal to 0. The data did not follow a simple Michaelis-Menten equation.
