Dissolved organic phosphorus bond-class utilization by Synechococcus [PDF]

FEMS Microbiology Ecology
Abstract Dissolved organic phosphorus (DOP) contains compounds with phosphoester, phosphoanhydride, and phosphorus–carbon bonds. While DOP holds significant nutritional value for marine microorganisms, the bioavailability of each bond-class to the widespread cyanobacterium Synechococcus remains largely unknown.

Atmospheric deposition and river runoff stimulate the utilization of dissolved organic phosphorus in coastal seas [PDF]

Nature Communications
In coastal seas, the role of atmospheric deposition and river runoff in dissolved organic phosphorus (DOP) utilization is not well understood. Here, we address this knowledge gap by combining microcosm experiments with a global approach considering the ...

Depth-dependent effects of crop rotation and monoculture on dissolved organic matter quantity and quality [PDF]

Frontiers in Plant Science
IntroductionSoil dissolved organic matter (DOM) regulates nutrient cycling and carbon sequestration, yet how cropping systems (rotation vs. monoculture) shape the vertical distribution and molecular traits of DOM remains unclear.MethodsWe leveraged a ...

Transitions in Dissolved Organic Phosphorus and Dissolved Organic Carbon Across a Freshwater Estuary Gradient

Journal of Geophysical Research: Biogeosciences, 2023
AbstractDespite the significant role that dissolved organic phosphorus (DOP) plays in ecosystem productivity, efforts to characterize inputs of phosphorus (P) into lakes have largely ignored P fractions complexed to dissolved organic matter (DOM). To address this gap, we characterized DOP and DOM along a transect of a Lake Erie tributary (Kettle Creek)

Deep-water inflow event increases sedimentary phosphorus release on a multi-year scale [PDF]

Biogeosciences, 2021
Phosphorus fertilisation (eutrophication) is expanding oxygen depletion in coastal systems worldwide. Under low-oxygen bottom water conditions, phosphorus release from the sediment is elevated, which further stimulates primary production.

Dissolved organic phosphorus uptake by marine phytoplankton is enhanced by the presence of dissolved organic nitrogen [PDF]

Journal of Experimental Marine Biology and Ecology, 2020
Abstract Organic nutrients can constitute the major fractions (up to 70%) of aquatic nitrogen (N) and phosphorus (P), but their cycling is poorly understood relative to the inorganic pools. Some phytoplankton species access P from the dissolved organic phosphorus (DOP) pool through expression of alkaline phosphatase (AP), which hydrolyses ...

Evidence for the leaching of dissolved organic phosphorus to depth

Science of The Total Environment, 2021
Phosphorus (P) can leach from topsoil in inorganic and organic forms. While some evidence has shown inorganic P (orthophosphate) can leach to depth in some soils, less is known of dissolved organic P (DOP). This is not helped by a paucity of DOP data for groundwater.

Nutrient removal in a slow-flowing constructed wetland treating aquaculture effluent

Aquaculture Environment Interactions, 2021
Danish model trout farms (MTFs) use stream-like constructed wetlands for effluent polishing, and the industry is keen to improve wetland removal efficiency.

New insights on resource stoichiometry: assessing availability of carbon, nitrogen, and phosphorus to bacterioplankton [PDF]

Biogeosciences, 2017
Boreal lake and river ecosystems receive large quantities of organic nutrients and carbon (C) from their catchments. How bacterioplankton respond to these inputs is not well understood, in part because we base our understanding and predictions on total ...
