Lack-of P-limitation of phytoplankton and heterotrophic prokaryotes in surface waters of three anticyclonic eddies in the stratified Mediterranean Sea (2011, background): “…surface waters during the stratified period, specific PO4 affinities are close to their respective theoretical maxima which are predicted from the assumption that molecular diffusion to the cell surface is the rate-limiting step (Moutin et al., 2002; Tanaka et al., 2003, 2004; Flaten et al., 2005).”
Population Dynamics of Harmful Cyanobacteria (2005, background): “In particular, small picocyanobacteria like Synechococcus and Synechocystis are very efficient competitors for phosphorus ( Moutin et al., 2002; J. Passarge, unpublished results).”
P-limited bacteria but N and P co-limited phytoplankton in the Eastern Mediterranean—a microcosm experiment (2005, background): “Moutin et al. (2002) and Tanaka et al. (2003) have shown that Synechococcus has PO4 uptake kinetics (affinity, maximum uptake rate) superior to those of bacteria and eukaryotic algae, which allows it to outcompete other species when PO4 becomes available.”
Bacterial response to dust pulses in the western Mediterranean: Implications for carbon cycling in the oligotrophic ocean (2008, methodology): “…SRP inputs (particularly those associated to the above mentioned Saharan event) were substantial compared to in situ concentration during the stratification period which, despite not being measurable with the method used in this study, has been reported to be below 3 nmol L 1 [Moutin et al., 2002].”
Phytoplankton taxon-specific orthophosphate (Pi) and ATP utilization in the western subtropical North Atlantic (2009, background): “This is likely due to induction of various P-acquisition and P-metabolism pathways, which differ between phytoplankton species, as well as differences in the point where diffusion limitation increases in importance, which is related to cell size (Moutin et al. 2002, Lovdal et al. 2007).”
Ecotypic variation in phosphorus-acquisition mechanisms within marine picocyanobacteria (2005, background): “On the other hand, it has recently been reported that Synechococcus predominate in the Mediterranean Sea, possibly due to their high affinity for inorganic P (Pi) and significantly higher maximum uptake rates relative to other plankton (Moutin et al. 2002).”
Dynamics of Dissolved Organic Phosphorus (2015, methodology): “Moutin et al. (2002) used the Hudson et al. (2000) method to estimate bioavailable Pi turnover time and as an estimate of the pool size along a W to E transect in the central Mediterranean Sea.”
Oligotrophication and emergence of picocyanobacteria and a toxic dinoflagellate in Thau lagoon, southern France (2009, background): “Recent evidence from natural populations of Synechococcus from the 8 Mediterranean (Moutin et al., 2002; Tanaka et al., 2003) indicate Ks values for SRP uptake lie 9 between 0.02 and 0.05 µM.”
Picophytoplankton in Freshwater Ecosystems: The Importance of Small-Sized Phototrophs (2008, background): “We know that Synechococcus spp. have a high affinity for orthophosphate (Moutin et al., 2002) and a maximum cell specific P-uptake rate that is competitively superior to algae and other bacteria under a pulsed supply (Vadstein, 2000).”
Phosphate availability controls Trichodesmium spp. biomass in the SW Pacific Ocean (2005, methodology): “…Michaelis-Menten parameters obtained following the Marquardt-Levenberg minimization: Ks = 630 nM and Vmax sp. = 0.31 h–1 Mar Ecol Prog Ser 297: 15–21, 2005 tude of the calculated concentrations and allowed us to reach a sub-nanomolar detection limit (Moutin et al. 2002, Van Den Broeck et al. 2004).”
