Nutrient experiment using Phaeodactylum tricornutum as an assay organism
The growth of Phaeodactylum tricornutum, cultured at 7,000 lux and 25º C, in twelve-day experiments using enriched water collected at the surface and 50.0 m depth from coastal waters offshore of Ubatuba area, was carried out. Different water enrichements were made by the aseptic addition of several nutrients, at each depth, according to Smayda (1964). The nitrogen out measured in terms of Carbon-14 assimilation and cloropyll concentration, was found to be a primary limiting factor for marine phytoplankton production.
