Equations based on the kinetic model for estimating heterotrophic potential are derived which permit a linear kinetic analysis of the utilization of algal extracellular products by bacteria. Laboratory studies with a specific algal‐bacterial system suggest that the analysis will show changes in heterotrophic population size and in concentrations of extracellular products. Deviations from linear predictions of the model may also reveal aspects of the degree of specificity of algal‐bacterial interactions mediated by extracellular products. Application of the mixed substrate model may permit the detection and qualitative evaluation of the ecological significance of a phycosphere effect generated by algal blooms.
