On the other hand, knotweed plants grown on a high-phosphorus substrate (compost) exhibited a high phosphorus content but low contents of resveratrol and/or resveratrol derivatives.
The presence of melilot increased the concentration of resveratrol and/or resveratrol derivatives (Figs. 3b and 4b), but did not increase the concentration of phosphorus in knotweed grown on low-phosphorus substrates (Fig. 7).
This is in good agreement with the results of Longnecker and colleagues (2010), who also found higher proportions of active Cytophaga-Flavobacteria using a phosphorus containing substrate as marker compared with other substrates, such as leucine and thymidine.
After 10-day cultivation, the biomass, nitrogen, phosphorus, and organic substrate concentrations were analyzed, and content or production of DHA and TFA were determined.
(C) Pentavalent arsenicals are substrates (showing Km) or inhibitors (showing Ki) of many enzymes, as shown in Table S3 (Supporting Information), probably as a result of their mimicking a tetrahedral phosphorus atom in substrate or product analogues.
ZnO nanorod arrays were prepared on either fluorine-doped tin oxide (FTO) glass substrates or a Si 001) wafer substrates (phosphorus doped, 0.3~0.5 Ωcm).
Such Mannich-type N-phosphonomethylation is a common approach for phosphorus acid derived substrates and leads to multifunctional (phosphonic/amino/carboxylic) compounds of diverse relevance.
Ordering of the C-terminus upon the active site induces close juxtaposition of the incoming nucleophile attacker water oxygen and the α-phosphorus of the substrate, decreasing their distance below the van der Waals limit.
As shown in the inset, the current is injected into the wires from a 2-μm radius metallic tip on the external sidewall p-doped layer and collected through the n-core wire, the AlN/SiN x interface and the 275-μm-thick Si substrate (phosphorus-doped with a 10−2 Ω cm resistivity).
The C/P ratio was calculated by dividing the percentage of carbon in the substrates by the percentage of phosphorus in the same substrates.
Phosphate glass has a substrate of phosphorus pentoxide (P2O5), rather than the silica (SiO2) of conventional silicate glasses.
