Importance of dissolved organic nitrogen and phosphorus to biological nutrient cycling

Deep Sea Research Part A. Oceanographic Research Papers, 1985
Abstract Dissolved organic nitrogen (DON) and dissolved organic phosphorus (DOP) are large and important fractions of oceanic nutrient pools, especially in euphotic zones. Their inclusion with nitrate (NO3) and phosphate (PO4) to form total dissolved nitrogen and total dissolved phosphate improves the Redfield argument linking organism N:P values ...

Processes Influencing Dissolved Organic Nitrogen, Phosphorus and Sulphur in Soils

Chemistry and Ecology, 1993
Abstract The influence of different plant and soil processes on the concentrations of soluble organic forms of carbon, nitrogen, phosphorus and sulphur in soil and drainage waters is reviewed. Current knowledge about soluble organic matter is restricted mainly to dissolved organic carbon.

DISSOLVED ORGANIC PHOSPHORUS EXCRETION BY MARINE PHYTOPLANKTON1,2

Journal of Phycology, 1970
SUMMARYThe amounts of extracellular dissolved organic phosphorus (DOP) produced by 8 species of marine planktonic algae under various conditions of light, salinity, and nutrition were compared. Large amounts, more than 20% of the total P in the system, were excreted by Cyclotella cryptica, Thalassiosira fluviatilis, Dunaliella tertiolecta, and ...

Birnessite-Mediated Phosphorus Transformation and Speciation in Dissolved and Soil Organic Matter

Environmental Science & Technology
Phosphorus (P) speciation in natural environments is shaped by mineral interactions. Manganese oxy(hydr)oxides (MnOx) are powerful oxidants in nature and may promote the oxidative transformation of organic P compounds; yet little is known about the role of MnOx in the molecular transformation and speciation of P from natural organic matter.

Phosphorus Enhances Uptake of Dissolved Organic Matter in Boreal Streams

Ecosystems, 2017
Retention of carbon (C), either by physical mechanisms or microbial uptake, is a key driver of the transformation and storage of C and nutrients within ecosystems. Both the molecular composition and nutrient content of organic matter influence the rate at which it is retained in streams, but the relative influence of these characteristics remains ...

Removal mechanisms and metabolic responses of Chlorella pyrenoidosa to dissolved organic phosphorus

Bioresource Technology
Microalgae-based biotechnology holds significant potential for addressing dual challenges of phosphorus removal and recovery from wastewater; however, the removal mechanism and metabolic adaptation of microalgae to dissolved organic phosphorus (DOP) are still unclear.

Mineralization of dissolved organic phosphorus from a shallow eutrophic lake

Hydrobiologia, 1991
Release of soluble reactive phosphorus (SRP) from dissolved organic phosphorus (DOP), concentrated by reverse osmosis of water samples from Lough Neagh Northern Ireland, was measured in the presence of enzymes and cultures of lake water bacteria in a basal liquid medium adjusted to the pH of lake water (7.6).
