TDP (μM) under ${\mathrm{NO}}_3^{-}$ starvation and optimal ${\mathrm{NO}}_3^{-}$ conditions. (A) TDP consumption (μM) under ${\mathrm{NO}}_3^{-}$ starvation and ${\mathrm{NO}}_3^{-}$ optimal conditions. (B) TDP consumption in the re-inoculated conditions in [Low ${\mathrm{P}\mathrm{O}}_4^{3-}$–Low Fe] (under ${\mathrm{NO}}_3^{-}$ starvation and ${\mathrm{NO}}_3^{-}$ optimal conditions). ${\mathrm{P}\mathrm{O}}_4^{3-}$ is represented as Pi. Values are the mean, and the error bar is the spanning range between the duplicate measurements. In (A), letters indicate significant differences (p < 0.05) by t student test.
