Although it is established that labile fractions of dissolved organic nitrogen (DON), such as dissolved free amino acids (DFAA), can be utilized by microalgae, few studies have considered their quantitative importance for microphytobenthos (MPB). Mixed MPB communities, from 1 and 20 m water depth and treated in 2 ways (semi-natural and isolated), and axenic diatom cultures (Cylindrotheca fusiformis) were examined for the uptake of DFAA. Uptake was measured using naturally low concentrations (<1… CONTINUE READING
