Thalassia testudinum phosphate uptake kinetics at low in situ concentrations using a 33 P radioisotope technique
Thalassia testudinum phosphate uptake situ concentrations
2014/4/23
A new 33
P-tracer technique was used to define low-level phosphate (Pi) uptake kinetics for a dominant tropical
seagrass, Thalassia testudinum. We established seagrass Pi uptake kinetics at hi...
Heterogeneous oxidation of saturated organic aerosols by hydroxyl radicals: uptake kinetics, condensed-phase products, and particle size change
Heterogeneous oxidation saturated organic aerosols hydroxyl radicals uptake kinetics
2008/12/17
The kinetics and reaction mechanism for the heterogeneous oxidation of saturated organic aerosols by gas-phase OH radicals were investigated under NOx-free conditions. The reaction of 150 nm diameter ...
Optimization-based model of multinutrient uptake kinetics
Optimization-based model multinutrient uptake kinetics
2014/4/22
We present a new, optimization-based model for uptake kinetics of multiple nutrients, which has the same number of parameters (two for each nutrient) as the Michaelis-Menten model. We fit this model a...
We measured short-term uptake rates of copper using the gamma-emitting radioisotope 67Cu in seven algal species in natural and artificial seawater. Cellular net uptake of Cu was typically rapid over p...
Effect of iron deficiency on diatom cell size and silicic acid uptake kinetics
iron deficiency diatom cell size silicic acid uptake kinetics
2014/5/19
We studied the silicic acid uptake kinetics of the pennate diatom Cylindrotheca fusiformis grown under a wide range of iron concentrations (from Fe-limiting to Fe-sufficient conditions) to assess the ...
