Extract

There is increasing evidence that the specific growth rates of phytoplankton are hyperbolically related to the intracellular concentrations of rate-determining nutrients by expressions of the Michaelis-Menten type used in the study of enzyme reaction kinetics (see, for example, Caperon, 1968; Droop, 1968; Davies, 1970; Paasche, 1973). This has led us to inquire whether there might also be relationships, analogous to those which describe the effect of inhibitors upon the rates of enzyme reactions (Dixon & Webb, 1958) which can be applied to the growth of phytoplankton in the presence of sublethal levels of toxic substances.
