Ammonium Uptake by Micronesian Species of Gracilaria (Rhodophyta)

摘要

Research was carried out to examine the kinetics of ammonium uptake by thalli of several Gracilaria species from Micronesia to evaluate their relative potential for removing ammonium from mariculture systems. It was found that ammonium uptake was dependent upon substrate concentration, and that the uptake kinetics were consistent with a diffusive ammonium uptake process, as shown for ammonium depletion curves of ammonium concentration versus time for each species.
