Oligotrophic bacteria enhance algal growth under iron-deficient conditions
Open accessAbstract
A Halomonas sp., a marine halophilic and oligotrophic bacterium, was grown on exudates of Dunaliella bardawil. The bacteria increased the solubility of Fe, thereby enhancing its availability to the algae. As a result, the algal growth rate increased. Because of these syntrophic relations, growth of the marine alga D. bardawil was facilitated at Fe levels that would otherwise induce Fe deficiency and inhibit algal growth.

Cultivation of Dunaliella bardawil with Halomonas sp. under iron deficiency increased Fe solubility, enhancing its availability to algae and significantly improving algal growth rate.
“The cultivation of Dunaliella bardawil with Halomonas sp. isolated from algae cultures highlighted the siderophores’ key role in microalgal growth under iron deficiency. The bacteria increased Fe solubility, in this way enhancing its availability to the algae, which in turn significantly improved the algal growth rate [56].”

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.
