From: Modifying the thickness, pore size, and composition of diatom frustule in Craspedostauros sp. with Al3+ ions

Figure 5

(a) Cell density measurements of C. sp. at different Al3+ concentrations as a function of cultivation time and Atomic absorption spectroscopy of decreasing silicon concentration in the different culture media as a function of cultivation time. Error bars indicate standard deviations for three culture replicates. On day 4th p ≤ 0.05. (b) Thermogravimetric analysis (TGA) in air, of C. sp. frustule material grown at different Al3+ concentrations.
