Uptake of Spartina-derived humic nitrogen by estuarine phytoplankton in nonaxenic and axenic culture
Humic substances are a collection of colored organic acids characterized by high molecular weight and low nitrogen (N) content that are thought to be biologically recalcitrant. We examined a suite of nonaxenic estuarine phytoplankton isolates to determine their ability to take up 15N-labeled humic substances formed in the laboratory and supplied as the sole N source. All 17 estuarine and coasta...
متن کاملAccelerated uptake by phytoplankton of iron bound to humic acids
Most of the dissolved iron (Fe) in seawater is complexed by organic ligands. One key issue in understanding Fe limitation in the sea is the bioavailability of different forms of Fe to marine phytoplankton. We measured Fe uptake by the coastal diatom Thalassiosira pseudonana and the cyanobacterium Synechococcus sp., using model ligands desferrioxamine B (DFB) and ferrichrome (FC), humic acids (H...
متن کاملNitrogen uptake by the shoots of smooth cordgrass Spartina alterniflora
The smooth cordgrass Spartina alterniflora is the foundation species in intertidal salt marshes of the North American Atlantic coast. Depending on its elevation within the marsh, S. alterniflora may be submerged for several hours per day. Previous ecosystem-level studies have demonstrated that S. alterniflora marshes are a net sink for nitrogen (N), and that removal of N from flooding tidal wat...
متن کاملAXENIC CULTURE AND CRYOPRESERVATION OF GIARDIA LAMBLIA ISOLATED IN IRAN
Giardia lamblia cysts were isolated from fecal samples of 55 symptomatic and asymptomatic patients with giardiasis. The cysts were harvested and purified using the sucrose gradient method. IS The excystation of G. lamblia was obtained by treating them with HCI (0.01N)', then they were transferred on to modified TYI-S-33 medium. Out of 55 stool samples 17 cases were excysted with a rate of ...
