Abstract

Portions of a phosphorus-deficient culture of Phaeodactylum tricornutum Bohlin were dispensed into fresh media containing phosphate concentrations from 8 to 80 µM. The instantaneous initial phosphate uptake rates were 12 to 24 x 10-17 mole/cell·min. The concentrations of phosphorus in the cells extended from a high of 66 x 10-15 mole/cell after 12 hours' exposure to phosphate-rich (32 and 80 µM) media to a low of 2 x 10-15 mole/cell when PO4 depletion of the medium limited further growth. In another experiment Phaeodactylum was prepared with varying intracellular P concentrations in media with very low PO4 concentrations. Radioactive phosphate was then added, the time course of P32 distribution was followed, and the rate of phosphate uptake was calculated. The initial rates ranged from 10-17 to 3 x 10-17 mole/cell·min. These were about one order of magnitude less than the uptake rates during the first two hours of the first experiment, even though the PO4 concentrations were two to four orders of magnitude lower. Radioisotope analysis showed that Phaeodactylum decreased the phosphate in the medium to as little as 7.2 x 10-10 M, a concentration much below the limit of sensitivity of the chemical analytical method.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
