Figure 3. Cellular concentration of (a-c) total phosphorus (TP) and (d-f) inorganic polyphosphate (Poly-P) in treatments A-H of the (a, d) nutrient-enriched (+NP), (b, e) phosphorus-limited (-P), and (c, f) nitrogen-limited (-N) toxicity tests for Microcystis aeruginosa PCC 7806 (WT, black bar) and its MC-lacking mutant (MT, white bar).

Figure 3

All values were normalized to levels (100% as represented by the dashed lines) detected in the WT strain at the lowest respective Cd concentration (Treatment A). Cd concentration in treatments A-H ([Cd]T, 1.00×10-8—9.95×10-6 M; [Cd2+]F, 1.00×10-13—1.21×10-8 M) is listed in Table B of S1 File. Data are mean ± standard error (n = 2)
