Utilization of HCO 3 − at high pH by the brown macroalga Laminaria saccharina
Open accessAbstract
The brown macroalga Laminaria saccharina exhibits a type of HCO3 − utilization that could be almost completely inhibited either by proton buffers or by acetazolamide, an inhibitor of extracellularly operating carbonic anhydrase. This means of HCO3 − utilization featured properties similar to direct HCO3 − uptake in that photosynthetic rates were proportional to the HCO3 − concentration of the seawater over a wide pH range (pH 7.0−9.5). Despite this, it must be characterized as carbonic anhydrase-catalysed external HCO3 − dehydration and not as direct HCO3 − uptake. A mechanism is suggested involving a CO2-concentrating capability located at the cell membrane. This mechanism, which might be common in brown algae, is suggested to have an adaptational advantage in colder regions of the sea (as compared with the direct HCO3 − uptake of green macroalgae). This means of HCO3 − utilization is inhibited even by fairly low concentrations of buffer, with consequences for the interpretation of earlier experimental studies on L. saccharina (and possibly other brown algae). These consequences relate both to ecology (e.g. determination of inorganic C affinity) and physiology (e.g. assessing mechanisms for inorganic C uptake).

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.
