Utilization of dissolved organic phosphorus by different groups of phytoplankton taxa

Effects of phosphorus deficiency and adenosine 5′-triphosphate (ATP) on growth and cell cycle of the dinoflagellate Prorocentrum donghaiense

“…It would be expected that hydrolysis and subsequent transport of the DOP-derived phosphate (or transport of DOP followed by intracellular hydrolysis) would cost energy, and hence would only partially restore growth of a phytoplankton population experiencing DIP deficiency. Therefore, DOP-based growth would be slower than DIP-based growth (Zhao-hui Wang et al, 2011). Our results showed that it was not the case in Prorocentrum donghaiense grown with ATP as the sole source of phosphorus.…”

Elevated CO 2 and Phosphate Limitation Favor Micromonas pusilla through Stimulated Growth and Reduced Viral Impact

“…However, to what extent the presence of organic phosphorus compounds, which can be up to 5 times as high as the soluble reactive (inorganic) phosphorus concentration in the open ocean (70), can counteract this effect is still unknown. Certain phytoplankton groups have been shown to be able to utilize different compounds, such as phosphomonoesters and nucleotides (71). The presence of alkaline phosphatase in M. pusilla suggests that it is able to assimilate certain organic phosphorus compounds.…”

Biomass production and nutrient removal by Chlorella sp. as affected by sludge liquor concentration

“…A substantial part can be adsorbed to the cell wall as mentioned in section 3.2 but algae can also utilize a subset of dissolved organic P (DOP) compounds by hydrolyzing them into dissolved inorganic phosphorus (DIP) with the alkaline enzyme phosphatase (APase) at P limitation (Cembella et al, 1984b;Wang et al, 2011). It is also possible that bacteria are breaking down DOP into DIP (Zhao et al, 2012), and the lowering in pH when diluting with effluent water may have released some metal complexes.…”
